LE CENTRE DE FRANCISCO CONTINUE DE S'ENFONCER DANS LES TERRES, EN
DIRECTION DES HAUTS PLATEAUX. LE SYSTEME S'AFFAIBLIT RAPIDEMENT SUR
TERRE MAIS RESTE UNE MENACE DE FORTE PLUIE POUR CERTAINES PARTIES DE
LA REGION EST ET CENTRALE DE MADAGASCAR AU COURS DES PROCHAINS JOURS.

UNE ACTIVITE PLUVIO-ORAGEUSE IRREGULIERE VA SE MAINTENIR SUR LA
PARTIE ORIENTALE DE MADAGASCAR, CELLE-CI A GAGNE L'INTERIEUR DES
TERRES EN COURS DE JOURNEE ET DEVRAIT SE MAINTENIR EN JOURNA E DE
DEMAIN. DES CUMULS PLUVIEUX CONSEQUENTS SONT A ATTENDRE, EN
PARTICULIER AU VOISINAGE DU 20EME PARALLELE SUD, MAIS EGALEMENT PLUS
AU SUD SUR LA PARTIE COTIERE (JUSQU'A FARAFANGANA), PLUS AU NORD DANS
LA REGION DE TAMATAVE AINSI QUE SUR LA CHAINE MONTAGNEUSE INTERIEURE.
AU COURS DES PROCHAINS JOURS, DES CUMULS ADDITIONELS DE L'ORDRE DE
100 A 150 MM EN 24H SONT PROBABLES SUR CES REGIONS AVEC DES VALEURS
LOCALEMENT PLUS IMPORTANTES AU NIVEAU DE LA CHAINE MONTAGNEUSE.

EN FIN DE WEEK-END, UN MINIMUM DEPRESSIONNAIRE RESIDUEL POURRAIT
RESSORTIR EN MER SUR LE CANAL DU MOZAMBIQUE A UN STADE TRES AFFAIBLI.
AUCUNE REINTENSIFICATION N'EST TOUTEFOIS ENVISAGEE, L'ENVIRONNEMENT
ETANT DEFAVORABLE, AVEC NOTAMMENT UN FORT CISAILLEMENT DE NORD-OUEST.

2.C ADDITIONAL INFORMATION:
THE CENTRE OF FRANCISCO GOES ON TRACKING OVERLAND TOWARD THE
HIGHLANDS. FRANCISCO IS WEAKENING AND FILL RAPIDLY BUT WILL REMAIN A
FLOOD THREAT FOR SOME PARTS OF EASTERN AND CENTRAL MADAGASCAR OVER
THE NEXT FEW DAYS.

RAIN AND THUNDERSTORM ACTIVITY WILL CONTINUE OVER THE EASTERN PART OF
MADAGASCAR, IT HAS SPREADED MORE INLAND TODAY. IT MAY MAINTAIN AN
IMPORTANT ACTIVITY TOMORROW. QUITE SIGNIFICANT RAINFALL AMOUNTS ARE
EXPECTED, IN PARTICULAR NEAR LATITUDE 20 DEGREES SOUTH BUT ALSO
LOCALLY SOUTHWARD ALONG THE COAST (DOWN TO FARAFANGANA AREA),
NORTHWARDS UP TO TAMATAVE AND ALSO IN THE MOUNTAIN RANGE TO THE WEST.
ADDITIONAL RAINFALL AMOUNTS MAY LIKELY REACHING 100 TO 150 MM IN 24H,
LOCALLY MORE PARTICULARLY OVER MOUNTAINOUS AREAS.

BY THE END OF THE WEEK-END THE RESIDUAL WEAKENED LOW CIRCULATION
COULD COME BACK OVER SEA IN THE MOZAMBIQUE CHANNEL. HOWEVER,
ENVIRONMENTAL CONDITIONS ARE VERY UNFAVORABLE FOR A
RE-INTENSIFICATION (WITH STRONG NORTHWESTERLY SHEAR IN PARTICULAR).

THIS IS THE LAST WARNING ABOUT THIS SYSTEM.=

L'ACTIVITE CONVECTIVE QUI A ETE TRES FLUCTUANTE DEPUIS HIER A REPRIS
EN COURS DE NUIT AVEC LE CYCLE DIURNE. LES ORBITES MICRO-ONDES
ACQUISES EN FIN DE NUIT (GPM EN PARTICULIER) MONTRENT UN VORTEX DE
TRES PETITE TAILLE MAIS A LA VORTICITE EXTREMEMENT AFFIRMEE, AVEC
PRESENCE D'UN SIMILI OEIL DE BASSES COUCHES. AU VU DE CETTE STRUCTURE
MICRO-ONDE ET MALGRE UNE CONFIGURATION NUAGEUSE PEU IMPRESSIONNANTE
SUR L'IMAGERIE CLASSIQUE, IL EST PLUS QUE PROBABLE QUE DES VENTS DE
LA FORCE DU COUP DE VENT SONT PRESENTS AU VOISINAGE DU RAYON DES
VENTS MAXIMAUX (ATTEIGNANT VRAISEMBLABLEMENT ENCORE TEMPORAIREMENT 40
KT DANS LE SECTEUR SUD-EST A EST DE LA CIRCULATION DEPRESSIONNAIRE).

LE CENTRE DE FRANCISCO EST CEPENDANT SUR LE POINT D'ATTERRIR SUR LA
COTE EST MALGACHE AU VOISINAGE DE LA LOCALITE DE MAHANORO ET LE
SYSTEME VA DONC RAPIDEMENT SE COMBLER ET LES VENTS S'AFFAIBLIR.

UNE ACTIVITA PLUVIO-ORAGEUSE IRREGULIERE VA SE MAINTENIR SUR LA
PARTIE ORIENTALE DE MADAGASCAR GAGNANT A L'INTERIEUR DES TERRES EN
FIN DE JOURNEE. DES CUMULS PLUVIEUX CONSEQUENTS SONT A ATTENDRE, EN
PARTICULIER AU VOISINAGE DU 20EME PARALLELE SUD, MAIS EGALEMENT PLUS
AU SUD SUR LA PARTIE COTIERE (JUSQU'A FARAFANGANA) ET LA CHAINE
MONTAGNEUSE INTERIEURE, ATTEIGNANT 100 A 150MM EN 24H, LOCALEMENT
DAVANTAGE AU VOISINAGE DE 20 DEGRES SUD.

EN FIN DE WEEK-END, UN MINIMUM DEPRESSIONNAIRE RESIDUEL POURRAIT
RESSORTIR EN MER SUR LE CANAL DU MOZAMBIQUE A UN STADE TRES AFFAIBLI.
AUCUNE REINTENSIFICATION N'EST TOUTEFOIS ENVISAGEE, L'ENVIRONNEMENT
ETANT DEFAVORABLE, AVEC NOTAMMENT UN FORT CISAILLEMENT DE NORD-OUEST.=

CONVECTIVE ACTIVITY HAS BEEN VERY FLUCTUATING SINCE YESTERDAY BUT HAS
BURST OVERNIGHT BOOSTED BY THE DIURNAL CYCLE. THE MICROWAVE DATA
ACQUIRED AT THE END OF THE NIGHT (GPM SWATH IN PARTICULAR) REVEALED
THE PRESENCE OF A TIGHT BUT PROMINENT AND VERY-WELL DEFINED LOW-LEVEL
VORTEX SURROUNDING AN EYE-LIKE FEATURE. CONSIDERING THE MICROWAVE
STRUCTURE AND DESPITE A CLOUD PATTERN WHICH LOOKS RATHER INNOCUOUS ON
THE CONVENTIONAL IMAGERY, IT IS HIGHLY LIKELY THAT GALE FORCE WINDS
ARE PRESENT IN THE VICINITY OF THE RADIUS OF MAXIMUM WINDS (LIKELY
STILL TEMPORARILY REACHING 40KT IN THE EASTERN TO SOUTHEASTERN
PORTION OF THE CLOCKWISE CIRCULATION).

THE CENTRE OF THE MIDGET STORM IS ABOUT TO MAKE LANDFALL ON THE
EASTERN SEABOARD OF MADAGASCAR NEAR THE CITY OF MAHANORO. FRANCISCO
WILL THEREAFTER WEAKEN AND FILL RAPIDLY.

RAIN AND THUNDERSTORM ACTIVITY WILL CONTINUE OVER THE EASTERN PART OF
MADAGASCAR SPREADING MORE INLAND BY THE END OF THE DAY. QUITE
SIGNIFICANT RAINFALL AMOUNTS ARE EXPECTED, IN PARTICULAR NEAR
LATITUDE 20 DEGREES SOUTH BUT ALSO LOCALLY SOUTHWARD ALONG THE COAST
(DOWN TO FARAFANGANA AREA) AND IN THE MOUNTAIN RANGE TO THE WEST MAY
LIKELY REACHING 100 TO 150 MM IN 24H, LOCALLY MORE NEAR 20 DEGREES
SOUTH.

BY THE END OF THE WEEK-END THE RESIDUAL WEAKENED LOW CIRCULATION
COULD COME BACK OVER SEA IN THE MOZAMBIQUE CHANNEL. HOWEVER,
ENVIRONMENTAL CONDITIONS ARE VERY UNFAVORABLE FOR A
RE-INTENSIFICATION (WITH STRONG NORTHWESTERLY SHEAR IN PARTICULAR).=

UNE FORTE POUSSEE CONVECTIVE S'EST PRODUITE EN COURS DE NUIT DERNIERE
SUR L'ENSEMBLE DE LA CIRCULATION. L'ACTIVITE CONVECTIVE S'EST ENSUITE
BIEN MAINTENUE EN JOURNEE SUR LE QUADRANT SUD-OUEST EN PROFITANT DE
LA BONNE DIVERGENCE D'ALTITUDE COTE POLAIRE AINSI QUE D'UNE
AUGMENTATION DE LA CONVERGENCE DE SURFACE. LES PASSES ASCAT-A ET
ASCAT-C DE LA MATINEE MONTRENT UNE CIRCULATION DE SURFACE BIEN DA
FINIE AVEC DES VENTS ATTEIGNANTS 30KT SUR LE DEMI-CERCLE OUEST.

AVEC LE DECALAGE VERS L'EST DE LA CELLULE DE HAUTS GEOPOTENTIELS
SUBTROPICAUX, LE FLUX DIRECTEUR DE BASSE ET MOYENNE TROPO BASCULE AU
NORD-EST. AINSI, FRANCISCO DEVRAIT LONGER LA COTE MALGACHE VERS LE
SUD DEMAIN VENDREDI AVANT D'ATTERRIR EN JOURNEE OU SOIREE DE SAMEDI.
LES MODELES DISPONIBLES SONT PLUTOT EN BON ACCORD SUR CE SCENARIO.

LA BAISSE DE CISAILLEMENT ENVIRONNEMENTAL QUI A PERMIS LE REGAIN
D'ORGANISATION RESTE D'ACTUALITE AU COURS DES PROCHAINS JOURS. L'AIR
SEC DE MOYENNE TROPOSPHERE RESTE CEPENDANT PRESENT A L'EST. LA
PROXIMITE DES COTES MALGACHES DEVRAIT GENER LA CONVERGENCE DE BASSES
COUCHES. MALGRE CELA, FRANCISCO DEVRAIT PEU OU PROU MAINTENIR SON
INTENSITE ACTUELLE JUSQU'A SON ATTERRISSAGE.

AVEC LE RAPPROCHEMENT PUIS L'ATTERRISSAGE DE FRANCISCO, LES REGIONS
COTIERES SITUEES DE TAMATAVE A FARAFANGANA VONT ETRE AFFECTEES PAR
UNE ACTIVITA PLUVIO-ORAGEUSE INTENSE ET DURABLE. LES CUMULS PREVUS
SUR LES 5 PROCHAINS JOURS ATTEIGNENT 250MM, ET DEPASSENT 300MM
LOCALEMENT. LES REGIONS INTERIEURES, ET NOTAMMENT TANANARIVE,
DEVRAIENT ETRE CONCERNEES DANS UNE MOINDRE MESURE AVEC DES CUMULS PRA
VUS VERS 100MM SUR L'A PISODE.

EN DEBUT DE SEMAINE PROCHAINE, CERTAINS MEMBRES DE LA PREVISION
D'ENSEMBLE PROPOSE UNE RESSORTIE EN MER SUR LE CANAL DU MOZAMBIQUE A
UN STADE TRES AFFAIBLI. L'ENVIRONNEMENT EST CEPENDANT TRES
DEFAVORABLE A UNE REINTENSIFICATION AVEC NOTAMMENT UN FORT
CISAILLEMENT DE NORD-OUEST.

SI INTENSIFICATION, UN BULLETIN SERA EMIS DEMAIN AVANT ATTERRISSAGE.=

A STRONG CONVECTIVE BURST TRIGGERED OVERNIGHT ON THE ENTIRE
CIRCULATION. CONVECTIVE ACTIVITY MAINTAINED QUITE WELL OVER THE
SOUTHWESTERN QUADRANT BENEFITING FROM A GOOD POLEWARD UPPER
DIVERGENCE AS WELL AS A BETTER SURFACE CONVERGENCE. THE ASCAT-A AND
ASCAT-C SWATHS SHOWED A WELL-DEFINED SURFACE CIRCULATION WITH WINDS
REACHING 30KT IN THE WESTERN SEMI-CIRCLE.

WITH THE EASTWARD SHIFT OF THE SUBTROPICAL HIGH CELL, THE LOW-MID
LEVEL STEERING FLOW IS BACKING NORTHEASTERLY. THUS, FRANCISCO SHOULD
TRACK SOUTHWARD ALONG THE MADAGASCAN COASTLINE TOMORROW FRIDAY,
BEFORE LANDING SATURDAY. THE AVAILABLE GUIDANCE IS IN RATHER GOOD
AGREEMENT OVER THIS SCENARIO.

THE ENVIRONMENTAL WIND SHEAR REMAINS LOW OVER THE WEEK-END. MID-LEVEL
DRY AIR IS STILL LOCATED IN THE EAST. THE VICINITY OF THE MADAGASCAN
COASTLINE SHOULD DISTURB THE LOW-LEVEL ORGANISATION. HOWEVER,
FRANCISCO IS EXPECTED TO GLOBALLY MAINTAIN ITS CURRENT INTENSITY
UNTIL ITS LANDFALL.

TONIGHT, WITH FRANCISCO COMING CLOSER BEFORE LANDING ON MADAGASCAR,
THE COASTAL REGIONS LOCATED FROM TAMATAVE TO FARAFANGANA SHOULD BE
AFFECTED BY A STRONG AND DURABLE THUNDERSTORM ACTIVITY. THE
ACCUMULATED RAINFALL OVER THE NEXT 5 DAYS COULD REACH 250MM AND
EXCEED 300MM LOCALLY. TO A LESSER EXTENT, THE MOUNTAINOUS REGIONS
INLAND, INCLUDING TANANARIVE, SHOULD ALSO BE AFFECTED WITH
ACCUMULATED RAINFALL REACHING 100MM OVER THE EPISODE.

IN THE BEGINNING OF NEXT WEEK, SOME MEMBERS OF THE ENSEMBLE
PREDICTION SUGGEST THAT A VERY WEAKENED RESIDUAL CIRCULATION COULD
COME BACK OVER SEA IN THE MOZAMBIQUE CHANNEL. HOWEVER, ENVIRONMENTAL
CONDITIONS ARE VERY UNFAVORABLE FOR A RE-INTENSIFICATION WITH AN

2.C COMMENTAIRES:
AU COURS DES DERNIERES 6 H, LA CONVECTION A TOTALEMENT DESERTE LA
CIRCULATION PRINCIPALE. ELLE N'EST PLUS PRESENTE QUE DANS LE SILLAGE
DU SYSTEME, LOIN DANS LE QUADRANT SUD-EST. LE VORTEX DE NUAGES DE
BASSES COUCHES RESTE ENCORE BIEN SYMMETRIQUE.

FRANCISCO A FINI PAR BUTER DANS LES HAUTES PRESSIONS SUBTROPICALES AU
SUD ET SE DEPLACE DESORMAIS VERS L'OUEST. AU COURS DES PROCHAINS
JOURS, IL DEVRAIT CONTINUER A DERIVER L'OUEST-SUD-OUEST PRIS DANS LE
FLUX DIRECTEUR DE BASSES COUCHES SUR LA FACE NORD DE LA CELLULE DES
HAUTES PRESSIONS SUBTROPICALES. UNE REMONTEE VERS LE NORD-OUEST EST
ENVISAGEE EN DEBUT DE SEMAINE PROCHAINE, MAIS AVEC UNE FORTE
DISPERSION DES MODELES.

L'AIR SEC DE MOYENNE TROPOSPHERE EMPECHE DESORMAIS LA CONVECTION DE
SE DECLENCHER SUR LE COEUR DE LA CIRCULATION. A PARTIR DE DEMAIN
SAMEDI, LES CONDITIONS VONT DEVENIR ENCORE PLUS DEFAVORABLES AVEC LE
RENFORCEMENT DU CISAILLEMENT DE SECTEUR NORD. LE SYSTEME VA DONC
EVOLUER EN DEPRESSION RESIDUELLE AVEC DU GRAND FRAIS PRESENT
UNIQUEMENT DANS LE DEMI-CERCLE SUD PAR EFFET DE GRADIENT.

EN SUIVANT CETTE PREVISION, FRANCISCO SE RAPPROCHE DES MASCAREIGNES
MAIS DU FAIT DE SON ETAT TRES AFFAIBLI, IL NE PRESENTE PAS DE RISQUE
NOTABLE.

CECI EST LE DERNIER BULLETIN EMIS PAR LE CMRS DE LA REUNION SUR CE
SYSTEME, SAUF REINTENSIFICATION.=

2.C ADDITIONAL INFORMATION:
OVER THE LAST 6H, CONVECTION TOTALLY DISAPPEARED OVER THE MAIN
CIRCULATION. IT IS ONLY LOCATED WITHIN THE WAKE OF THE SYSTEM, FAR
WITHIN THE SOUTHEASTERN QUADRANT. THE LOW-LEVEL CLOUDS VORTEX REMAINS
WELL DEFINED.

FRANCISCO FINALLY BUMPED INTO THE SUBTROPICAL HIGH PRESSURE BELT IN
THE SOUTH AND IS NOW TRACKING WESTWARD. OVER THE NEXT DAYS, IT SHOULD
KEEP ON DRIFTING WEST-SOUTH-WESTWARD STEERED BY THE LOW-LEVEL TRADE
WINDS ON THE NORTHERN SIDE OF THE SUBTROPICAL HIGH. A NORTHWESTERLY
TURN IS FORECAST FOR THE BEGINNING OF NEXT WEEK, BUT WITH A LARGE
SPREAD OF THE AVAILABLE GUIDANCE.

MID-LEVEL DRY AIR CURRENTLY PREVENTS ANY CONVECTION OVER THE
CIRCULATION CORE. FROM TOMORROW SATURDAY, CONDITIONS BECOME EVEN MORE
UNFAVORABLE WITH THE STRENGTHENING OF THE NORTHERLY VERTICAL
WINDSHEAR. THE SYSTEM WILL THEREFORE BECOME A RESIDUAL LOW WITH NEAR
GALE FROCE WINDS ONLY PRESENT FAR TO THE SOUTH BY GRADIENT EFFECT.

ON THIS TRACK, FRANCISCO COMES CLOSER TO THE MASCARENES BUT BECAUSE
OF ITS VERY WEAKENED STATE, IT DOES NOT POSE ANY SIGNIFICANT THREAT.

THIS IS THE LAST BULLETIN ISSUED BY RSMC LA REUNION CONCERNING THIS
SYSTEM, EXCEPT REINTENSIFICATION.=

2.C COMMENTAIRES:
LA CIRCULATION SEMBLE MIEUX DEFINIE APRES AVOIR BENEFICIE D'UNE
REPRISE TEMPORAIRE DE LA CONVECTION PLUS PROCHE DU CENTRE EN FIN DE
NUIT. CEPENDANT LES VENTS FORTS ET L'ACTIVITA CONVECTIVE RESTENT
CONCENTRES DANS LE DEMI-CERCLE SUD, L'AIR SEC DE MOYENNE TROPO
RESTANT TRES PRESENT SUR LA PARTIE NORD DE LA CIRCULATION. LA PASSE
ASCAT DU MATIN MONTRE LA PRESENCE DE GRAND FRAIS DANS LE GRADIENT DE
PRESSION, ATTEIGNANT TRES LOCALEMENT LE COUP DE VENT.

FRANCISCO POURSUIT SON RECOURBEMENT VERS LE SUD-OUEST ET DEVRAIT PAR
LA SUITE ORIENTER SA TRAJECTOIRE VERS L'OUEST-SUD-OUEST PRIS DANS LE
FLUX DIRECTEUR DE BASSES COUCHES SUR LA FACE NORD DE LA CELLULE DES
HAUTES PRESSIONS SUBTROPICALES.

AUJOURD'HUI, UNE BAISSE RELATIVE DU CISAILLEMENT POURRAIT PERMETTRE
UNE REPRISE TEMPORAIRE DE LA CONVECTION PLUS PROCHE DU CENTRE, AVANT
QUE LA CONTRAINTE NE SE RENFORCE DE NOUVEAU CE SOIR. CEPENDANT L'AIR
SEC DE MOYENNE TROPOSPHERE DEVRAIT ENCORE SERIEUSEMENT PERTURBER CES
EVENTUELLES POUSSES CONVECTIVES. A PARTIR DE SAMEDI, LES CONDITIONS
VONT DEVENIR TRA S DEFAVORABLES AVEC UN FORT CISAILLEMENT DE SECTEUR
NORD ET LA PRESENCE D'AIR SEC EN MOYENNE TROPOSPHERE. LE SYSTEME VA
DONC EVOLUER EN DEPRESSION RESIDUELLE AVEC DU GRAND FRAIS PRESENT
UNIQUEMENT DANS LE DEMI-CERCLE SUD PAR EFFET DE GRADIENT.

EN SUIVANT CETTE PREVISION, FRANCISCO SE RAPPROCHE DES MASCAREIGNES
MAIS DU FAIT DE SON AFFAIBLISSEMENT, IL NE PRESENTE PAS DE RISQUE
NOTABLE.

TROPICAL CYCLONE FORECAST WARNING (SOUTH-WEST INDIAN OCEAN)

0.A WARNING NUMBER: 12/8/20192020
1.A TROPICAL DISTURBANCE 8 (FRANCISCO)

2.A POSITION 2020/02/07 AT 0600 UTC:
WITHIN 20 NM RADIUS OF POINT 20.6 S / 70.7 E
(TWENTY DECIMAL SIX DEGREES SOUTH AND
SEVENTY DECIMAL SEVEN DEGREES EAST)
MOVEMENT: SOUTH-WEST 6 KT

3.A DVORAK ANALYSIS: NIL

120H: 2020/02/12 06 UTC: 18.9 S / 53.4 E, VENT MAX= 020 KT, REMNANT

2.C ADDITIONAL INFORMATION:
THE CIRCULATION SEEMS TO BE BETTER DEFINED AFTER BENEFITING FROM THE
TEMPORARY CONVECTIVE BURST THAT OCCURRED QUITE CLOSE TO THE CENTER
JUST BEFORE SUNRISE. HOWEVER, STRONG WINDS AND CONVECTION REMAIN
CONCENTRATED WITHIN THE SOUTHERN SEMI-CIRCLE WITH MID-LEVEL DRY AIR
OCCUPYING THE NORTHERN PART OF THE CIRCULATION. THIS MORNING ASCAT
SWATH SHOWS NEAR GALE FORCE IN THE PRESSURE GRADIENT, REACHING GALE
FORCE ONLY VERY LOCALLY.

FRANCISCO'S TRACK CONTINUES TO BEND SOUTHWESTWARD AND SHOULD
EVENTUALLY TRACK WESTSOUTHWESTWARD STEERED BY THE LOW LEVEL FLOW ON
THE NORTHERN SIDE OF THE SUBTROPICAL HIGH PRESSURE CELL.

TODAY, A RELATIVE WEAKENING IN VERTICAL SHEAR MAY ALLOW RESUMPTION OF
CONVECTION CLOSER TO THE CENTER, BEFORE THE CONSTRAINT STRENGTHENS
AGAIN THIS EVENING. HOWEVER, DRY AIR SHOULD SERIOUSLY DISTURB THOSE
EVENTUAL CONVECTIVE BURSTS. FROM SATURDAY, THE CONDITIONS BECOME VERY
UNFAVORABLE WITH STRONG NORTHERLY VERTICAL WINDSHEAR AND THE PRESENCE
OF DRY AIR IN MID-TROPOSPHERE. THE SYSTEM WILL THEREFORE BECOME A
RESIDUAL LOW WITH NEAR GALE FROCE WINDS ONLY PRESENT FAR TO THE SOUTH
BY GRADIENT EFFECT.

ON THIS TRACK, FRANCISCO COMES CLOSER TO THE MASCARENES BUT BECAUSE
OF ITS WEAKENING, IT DOES NOT POSE ANY SIGNIFICANT THREAT.=

DU CISAILLEMENT VERTICAL DE VENT DE NORD-OUEST LA CONVECTION PROFONDE
EST REJETEE LOIN DANS LE QUADRANT EST BIEN QUE LA CELLULE CONVECTIVE
QUI S'EST DEVELOPPEE HIER SOIR DANS LE QUADRANT SUD S'EST MAINTENUE.

FRANCISCO POURSUIT SON RECOURBEMENT VERS LE SUD-EST ET DEVRAIT PAR LA
SUITE ORIENTER SA TRAJECTOIRE VERS L'EST-SUD-EST PRIS DANS LE FLUX
DIRECTEUR DE BASSES COUCHES SUR LA FACE NORD DE LA CELLULE DES HAUTES
PRESSIONS SUBTROPICALES.

AUJOURD'HUI, UNE BAISSE RELATIVE DU CISAILLEMENT POURRAIT PERMETTRE
UNE REPRISE DE LA CONVECTION PLUS PROCHE DU CENTRE AVANT QUE CELUI-CI
SE RENFORCE DE NOUVEAU CE SOIR. A PARTIR DE SAMEDI, LES CONDITIONS
VONT DEVENIR TRA S DEFAVORABLE AVEC UN FORT CISAILLEMENT ET LA
PRESENCE D'AIR SEC EN MOYENNE TROPOSPHERE. LE SYSTEME VA DONC EVOLUER
EN DEPRESSION RESIDUELLE AVEC DES VENTS FORTS FAIBLISSANT

2.C ADDITIONAL INFORMATION:
THE CIRCULATION REMAINS WIDE WITH A ILL DEFINED CENTER. UNDER THE

REJECTED FAR AWAY IN THE EASTERN QUADRANT, BUT THE CONVECTIVE CELL
THAT DEVELOPED YESTERDAY IN THE SOUTH QUADRANT HAS REMAINED.

FRANCISCO CONTINUES BENDING SOUTHEAST AND SHOULD THEREFORE ORIENTATE
ITS TRACK EASTSOUTHEASTWARD STEERED BY THE LOW LEVEL FLOW ON THE
NORTHERN SIDE OF THE SUBTROPICAL HIGH PRESSURE CELL.

TODAY, A RELATIVE WEAKENING IN VERTICAL SHEAR MAY ALLOW RESUMPTION OF
CONVECTION CLOSER TO THE CENTER BEFORE ITS STRENGTHENING THIS
EVENING. FROM SATURDAY, THE CONDITIONS WILL BECOME VERY UNFAVORABLE
WITH STRONG VERTICAL WINDSHEAR AND THE PRESENCE OF DRY AIR IN
MID-TROPOSPHERE. THE SYSTEM WILL THEREFORE EVOLVE IN RESIDUAL
DEPRESSION WITH STRONG WINDS WEAKENING GRADUALLY ONLY PRESENT FAR TO

AU COURS DES DERNIERES 6 HEURES, AUCUNE DONNEE NE PERMET DE JUGER DE
LA CONSOLIDATION DE LA CIRCULATION DE FRANCISCO, QUI RESTE DONC ZONE
PERTURBEE. LES IMAGES INFRAROUGE MONTRENT UNE CONFIGURATION CISAILLEE
DE LA CONVECTION DE FRANCISCO QUI SE CONCENTRE DANS LE DEMI-CERCLE
EST. LES VENTS MAXIMAUX RESTENT ESTIMES A 35KT, EN L'ABSENCE DE
NOUVELLES DONNEES DIFFUSIOMETRES.

LA PREVISION EVOLUE AVEC UN LEGER DECALAGE DE LA TRAJECTOIRE VERS LE
SUD SUITE AUX DERNIERES ESTIMATIONS DU CENTRE A 12UTC. FRANSCISCO A
DONC BIEN ENTAMER SON RECOURBEMENT VERS LE SUD. PAR LA SUITE, LA
TRAJECTOIRE VA S'ORIENTER VERS L'EST-SUD-EST, PRIS DANS LE FLUX
DIRECTEUR DE BASSES COUCHES.

LE CISAILLEMENT VERTICAL DE VENT DE NORD-OUEST IMPACTE
SIGNIFICATIVEMENT LA CONVECTION ET CES CONDITIONS DEFAVORABLES VONT
SE MAINTENIR DURABLEMENT (CISAILLEMENT ET PRESENCE D'AIR SEC EN
MOYENNE TROPOSPHERE). LE SYSTEME VA DONC EVOLUER EN DEPRESSION
RESIDUELLE AVEC DES VENTS FORTS FAIBLISSANT GRADUELLEMENT UNIQUEMENT

2.C ADDITIONAL INFORMATION:
FT=2.0 CI=2.5

DURING THE LAST 6 HOURS, THERE IS NO DATA TO ASSESS THE CONSOLIDATION
OF LOW-LEVEL CLOCKWISE CIRCULATION OF FRANCISCO, WHICH THEREFORE
REMAINS A AREA OF DISTURBED WEATHER. THE INFRARED IMAGES SHOW A
SHEARED CLOUD PATTERN WITH CONVECTION CONCENTRATED IN THE EASTERN
SEMICIRCLE. THE MAXIMUM WINDS REMAIN ESTIMATED AT 35KT, IN THE
ABSENCE OF NEW SCATTEROMETER DATA.

THE FORECAST EVOLVES WITH A SLIGHT SOUTHWARD SHIFT OF THE TRACK
FOLLOWING THE LAST ESTIMATES FROM THE CENTRE AT 12UTC. FRANSCISCO HAS
THUS STARTED ITS SOUTHWARD CURVATURE. THEREAFTER, THE TRACK WILL BE
ORIENTED EAST-SOUTHEAST, WITHIN THE LOW LEVELS STEERING FLOW.

THE NORTH-WESTERLY VERTICAL WINDSHEAR STRONGLY IMPEDES THE CLOUD
PATTERN AND THIS UNFAVORABLE ENVIRONMENTAL CONDITIONS WILL CONTINUE
FOR A LONG TIME (STEADY SHEAR AND MID-LEVELS DRY AIR INTRUSION). THIS
LEADS TO THE FILLING UP OF THE LOW, ASSOCIATED WITH SLOWLY FADING
STRONG WINDS IN THE SOUTHERN SECTOR DUE TO THE GRADIENT EFFECT.

BY FOLLOWING THIS TRACK FORECAST, FRANCISCO IS CLOSE TO THE
MASCAREIGNES BUT BECAUSE OF ITS WEAKENING, IT DOES NOT PRESENT ANY
NOTABLE RISK.=

DANS LA CONTINUITE DES PRECEDENTES DONNEES ASCAT ET MICRO-ONDE, LES
DERNIERES DONNEES MONTRENT ENCORE UNE CIRCULATION DE BASSES COUCHES
TRES ALLONGEE QUI REND DIFFICILE LA LOCALISATION PRECISE D'UN CENTRE.
L'IMAGERIE MICRO-ONDE SSMI DE 0140UTC MONTRE QUE LE CENTRE TEND A SE
CONCENTRER DE NOUVEAU MAIS FRANCISCO RESTE ENCORE CLASSE EN ZONE
PERTURBEE AVEC DES VENTS ATTEIGNANT ENCORE LE COUP DE VENT DANS LE
DEMI-CERCLE SUD. LA CONVECTION RESTE TRES ACTIVE DANS LE QUADRANT
SUD-EST MAIS AUSSI AU NORD DU SYSTEME DANS LA ZONE DE CONVERGENCE DU
FLUX.

LA PREVISION DE TRAJECTOIRE EVOLUE PEU : BIEN QUE LA LOCALISATION
PRECISE SOIT DIFFICILE A ESTIMER, LE SYSTEME ENTAME UN RECOURBEMENT
VERS LE SUD. PAR LA SUITE, LA TRAJECTOIRE VA S'ORIENTER VERS
L'EST-SUD-EST, PRIS DANS LE FLUX DIRECTEUR DE BASSES COUCHES.

LE CISAILLEMENT VERTICAL DE VENT DE NORD-OUEST EST TOUJOURS BIEN
PRESENT ET IMPACTE SIGNIFICATIVEMENT LA CONVECTION. LES CONDITIONS
S'ANNONCENT MAINTENANT DURABLEMENT DEFAVORABLES (CISAILLEMENT ET
PRESENCE D'AIR SEC EN MOYENNE TROPOSPHERE) POUR LE SYSTEME QUI
DEVRAIT EVOLUER EN DEPRESSION RESIDUELLE AVEC DES VENTS FORTS
FAIBLISSANT GRADUELLEMENT UNIQUEMENT PRESENTS LOIN AU SUD PAR EFFET

IN THE CONTINUITY OF THE PREVIOUS ASCAT AND MICROWAVE DATA, THE
LATEST DATA STILL SHOW A VERY ELONGATED CLOCKWISE CIRCULATION WHERE
IT IS HARD TO FIND A CIRCULATION CENTER PRECISELY. THE 0140UTC SSMI
MICROWAVE IMAGERY SHOWS THAT THE CENTRE TENDS TO CONCENTRATE AGAIN
BUT FRANCISCO IS STILL CLASSED AS AN AREA OF DISTURBED WEATHER WITH
GALE FORCE WINDS HOWEVER PRESENT OVER THE SOUTHERN SEMI-CIRCLE. THE
CONVECTION REMAINS STRONG IN THE SOUTH-EAST QUADRANT BUT ALSO TO THE
NORTH OF THE SYSTEM IN THE CONVERGENCE OF THE FLOW.

THE TRACK FORECAST DOES NOT CHANGE : ALTHOUGH THE PRECISE LOCATION IS
DIFFICULT TO ESTIMATE, THE SYSTEM BEGINS TO BEND SOUTHWARDS.
THEREAFTER, THE TRACK WILL BE ORIENTED EAST-SOUTHEAST, WITHIN THE LOW
LEVELS STEERING FLOW.

THE NORTH-WESTERLY VERTICAL WINDSHEAR IS STILL PRESENT AND STRONGLY
IMPEDES THE CLOUD PATTERN. UNFAVORABLE ENVIRONMENTAL CONDITIONS ARE
NOW EXPECTED (STEADY SHEAR AND MID-LEVELS DRY AIR INTRUSION) LEADING
TO THE FILLING UP OF THE LOW, ASSOCIATED WITH SLOWLY FADING STRONG
WINDS IN THE SOUTHERN SECTOR DUE TO THE GRADIENT EFFECT.

BY FOLLOWING THIS TRACK FORECAST, FRANCISCO IS CLOSE TO THE
MASCAREIGNES BUT BECAUSE OF ITS WEAKENING, IT DOES NOT PRESENT ANY
NOTABLE RISK.=

LES DONNEES COMPLETES DE LA FAUCHEE ASCAT-B D'HIER SOIR ONT MONTRE
UNE CIRCULATION DE BASSES COUCHES TRES ALLONGEE PERMETTANT A PEINE DE
POSITIONNER UN CENTRE. L'IMAGERIE MICRO-ONDE SSMI DE 2252Z MONTRE UN
CENTRE TOUJOURS MAL DEFINI DE PLUS EN PLUS ELOIGNE DE LA CONVECTION
PROFONDE DANS LE QUADRANT SUD-EST. DANS CE CONTEXTE, FRANCISCO A ETE
CLASSIFIE EN ZONE PERTURBEE (PAS DE CENTRE DE SURFACE BIEN DEFINI)
AVEC DES VENTS ATTEIGNANT ENCORE LE COUP DE VENT DANS LE DEMI-CERCLE
SUD.

LE CISAILLEMENT VERTICAL DE VENT DE NORD-OUEST CONTINUE D'AUGMENTER
(25-30 KT A 21Z SELON LE CIMSS) ET IMPACTE SIGNIFICATIVEMENT LA

DEPRESSION RESIDUELLE AVEC DES VENTS FORTS FAIBLISSANT GRADUELLEMENT
UNIQUEMENT PRESENTS LOIN AU SUD PAR EFFET DE GRADIENT.

SANS FIX MICRO-ONDE FIABLE, LA POSITION EST TRES INCERTAINE EN RAISON

COMPLETE ASCAT-B DATA OF LAST NIGHT SHOW A VERY ELONGATED SURFACE
CIRCULATION WHERE IT IS HARD TO FIND A CIRCULATION CENTER. SSMI MW
IMAGERY AT 2252Z STILL SHOW AN ILL-DEFINED CENTER INCREASINGLY
DISTANT TO THE DEEP CONVECTION LOCATED OVER THE SOUTH-EASTERN
QUADRANT. BASED ON THAT, FRANCISCO IS NOW CLASSIFIED AS AN AREA OF
DISTURBED WEATHER (LACK OF A DEFINED SURFACE CENTER) WITH GALE FORCE
WINDS HOWEVER PRESENT OVER THE SOUTHERN SEMI-CIRCLE.

THE NORTH-WESTERLY VERTICAL WINDSHEAR HAS INCREASED AGAIN (25-30 KT
AT 21Z BASED ON CIMSS DATA) AND STRONGLY IMPEDES THE CLOUD PATTERN.
UNFAVORABLE ENVIRONMENTAL CONDITIONS ARE NOW EXPECTED (STEADY SHEAR
AND MID-LEVELS DRY AIR INTRUSION) LEADING TO THE FILLING UP OF THE
LOW, ASSOCIATED WITH SLOWLY FADING STRONG WINDS IN THE SOUTHERN
SECTOR DUE TO THE GRADIENT EFFECT.

WITH NO RELIABLE MW FIX, THE CENTER POSITION IS HIGHLY UNCERTAIN DUE
TO THE LACK OF WELL DEFINED SURFACE CIRCULATION CENTER. AS THE SYSTEM
IS EXPECTED TO WEAKEN TODAY, THE TRACK SHOULD TURN GENERALLY
WESTWARDS WITHIN THE LOW LEVELS STEERING FLOW.=

MW DATA OF THIS EVENING ALONG WITH ASCAT DATA REVEAL THAT FRANCISCO
HAS AN ILL-DEFINED CENTER WITHIN A STILL VERY ELONGATED CIRCULATION.
THE SATELLITE CLOUD PATTERN IS A SHEAR PATTERN WITH THE CENTER
LOCATED JUST OFF THE MAIN CONVECTION THAT IS UNDERGOING STRONG
FLUCTUATIONS IN THE SOUTH-EASTERN QUADRANT. THE FINAL INTENSITY IS
BASED ON THE HIGHER RELIABLE WINDS SHOWN BY THE ASCAT PASS.

THE NORTH-WESTERLY VERTICAL WINDSHEAR HAS INCREASED (24 KT AT 12Z
BASED ON CIMSS DATA) AND NOW STRONGLY IMPEDES THE CLOUD PATTERN AS
THE SYSTEM HAS SLOW DOWN SINCE THIS AFTERNOON. UNFAVORABLE
ENVIRONMENTAL CONDITIONS ARE NOW EXPECTED (STEADY SHEAR AND
MID-LEVELS DRY AIR INTRUSION) LEADING TO THE FILLING UP OF THE LOW,
ASSOCIATED WITH STRONG WINDS IN THE SOUTHERN SECTOR DUE TO THE
GRADIENT EFFECT.

MW FIX HAS SHOWN THAT THE SYSTEM HAS BEND EASTWARDS MORE THAN,
EXPECTED OVER THE SOUTHERN EDGE OF A LOW TO MID-LEVEL EQUATORIAL
RIDGE . AS THE SYSTEM IS EXPECTED TO WEAKEN, THE TRACK SHOULD TURN
GENERALLY WESTWARDS WITHIN THE LOW LEVELS STEERING FLOW.=

2.C COMMENTAIRES:
FT=CI=3.0

AU COURS DES DERNIERES 6H, LA CONFIGURATION NUAGEUSE A EVOLUE VERS UN
CDO AVEC DES SOMMETS TRES FROIDS. LES SIGNES DE CISAILLEMENT VERTICAL
DE VENT DE NORD-OUEST (ANALYSE A 19KT A 06Z PAR LE CIMSS) SONT DE
PLUS EN PLUS PRA SENT AVEC UNE CIRCULATION PARTIELLEMENT EXPOSA E
DANS LE QUADRANT OUEST. L'ESTIMATION D'INTENSITE EST EN ACCORD AVEC
L'ADT DU CIMSS.

UNE COURTE FENETRE DE CONDITIONS ENVIRONNEMENTALES ASSEZ FAVORABLES A
L'INTENSIFICATION EXISTE ENCORE EN CETTE FIN DE JOURNA E. LE
CISAILLEMENT VERTICAL DE VENT DE MODA RA NORD-OUEST RESTE COMPENSA
PAR UNE EXCELLENTE DIVERGENCE D'ALTITUDE CA TA POLAIRE EN ENTRA E
CHAUDE DU JET SUBTROPICALE. A PARTIR DE CETTE NUIT, LE SYSTEME SE
DECALE EN BORDURE DU JET ET VA SUBIR UNE HAUSSE DU CISAILLEMENT DE
NORD-OUEST ET UNE INTRUSION D'AIR SEC DE MOYENNE TROPOSPHERE. A
PARTIR DE DEMAIN ET AU DELA, LES CONDITIONS S'ANNONCENT DURABLEMENT
DEFAVORABLES POUR LE SYSTEME QUI DEVRAIT ALORS EVOLUER EN DEPRESSION
RESIDUELLE AVEC DES VENTS FORTS UNIQUEMENT PRESENTS LOIN AU SUD PAR
EFFET DE GRADIENT.

LA TRAJECTOIRE VERS LE SUD-EST EST PILOTEE PAR UNE DORSALE PROCHE
EQUATORIALE PRESENTE AU NORD-EST DU SYSTEME AVEC PRESENCE D'UNE
FAIBLESSE DE LA DORSALE SUBTROPICALE DANS LE SECTEUR SUD DU SYSTEME.
APRES LA PHASE D'AFFAIBLISSEMENT ATTENDUE CETTE NUIT ET DEMAIN, UN
REDRESSEMENT DE LA TRAJECTOIRE VERS LE SUD-OUEST DANS LE FLUX
DIRECTEUR DE BASSES COUCHES EST ENVISAGE. SI LA TRAJECTOIRE ACTUELLE
EST BASEE SUR UN CONSENSUS DES MODELES DISPONIBLES, ON NOTE UNE FORTE
DISPERSION DES GUIDANCES DES LA FIN DE JOURNEE EN LIEN AVEC LA PHASE
D'AFFAIBLISSEMENT.=

2.C ADDITIONAL INFORMATION:
FT=CI=3.0

OVER THE LAST 6 HOURS, THE CLOUD PATTERN HAS EVOLVED TOWARDS A CDO
WITH VERY COLD TOPS. THE SIGNS OF NORTHWESTERLY VERTICAL WIND SHEAR
(ANALYSIS AT 19KT AT 06Z BY CIMSS) ARE INCREASINGLY PRESENT WITH A
PARTIALLY EXPOSED CIRCULATION WITHIN THE WESTERN QUADRANT. THE
ESTIMATE OF INTENSITY IS IN AGREEMENT WITH THE ADT OF CIMSS.

A SHORT WINDOW OF ENVIRONMENTAL CONDITIONS ENOUGH FAVORABLE TO THE
INTENSIFICATION STILL AT THE END OF THE DAY WITH THE NORTHWESTERLY
VERTICAL WINDSHEAR COMPENSATED BY AN EXCELLENT POLARWARD UPPER LEVEL
DIVERGENCE IN WARM SUBTROPICAL JET ENTRANCE. FROM TONIGHT, THE SYSTEM
IS EXPECTED TO SHIFT IN THE VICINITY OF THE SUBTROPICAL JET AND WILL
EXPERIENCE AN INCREASED NORTHWESTERLY SHEAR AND AN INTRUSION OF MID
TROPOSPHERE DRY AIR. FROM TOMORROW AND BEYOND, UNFAVORABLE
ENVIRONMENTAL CONDITIONS ARE EXPECTED LEADING TO THE FILLING UP OF
THE LOW, ASSOCIATED WITH STRONG WINDS IN THE SOUTHERN SECTOR DUE TO
THE GRADIENT EFFECT.

THE CURRENT MOTION IS DRIVEN BY NEAR EQUATORIAL RIDGE LOCATED TO THE
NORTH-EAST AS THE SYSTEM IS LOCATED NORTH OF A WEAKNESS OF THE
SUBTROPICAL RIDGE. AS THE SYSTEM IS EXPECTED TO WEAKEN, THE TRACK
SHOULD TURN WESTWARDS OR SOUTHWESTWARDS WITHIN THE LOW LEVELS
STEERING FLOW. IF THE CURRENT TRACK IS BASED ON A CONSENSUS AVAILABLE
NUMERICAL GUIDANCE, IT SHOULD BE MENTIONED THAT THERE IS A
SIGNIFICANT SPREAD AMONG THE GUIDANCE FROM THE END OF THE DAY IN
RELATION WITH THE WEAKENING PHASE.=

CONTINUE TO TRACK SOUTHEAST TO SOUTH THROUGH TAU 36 UNTIL IT BEGINS
A WEST-SOUTHWESTWARD TRACK DUE TO INTERACTION WITH A BUILDING RIDGE
TO THE SOUTH. DURING THIS TIME, INCREASING VWS (35-40 KTS) FROM TAU
36 TO 96 WILL HINDER DEVELOPMENT AND WILL CAUSE THE SYSTEM TO WEAKEN
STEADILY. NUMERICAL MODELS ARE IN POOR AGREEMENT WITH A LARGE DEGREE
OF SPREAD AFTER TAU 24 (370 NM SPREAD AT TAU 72) LENDING LOW
CONFIDENCE TO THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 050600Z IS 15 FEET. NEXT WARNINGS AT 052100Z AND 060900Z.//

FT=CI=3.0

OVER THE LAST 6 HOURS, THE CLOUD PATTERN WAS IMPROVED. ALSO, THE
SYSTEM HAS BEEN NAMED AT 0300Z BY THE MAURITIUS METEOROLOGICAL
SERVICES. SINCE CONVECTION HAS REMAINED STRONG WITH THE FORMATION OF
A CURVED BAND. FOR ALL THAT, SIGNS OF VERTICAL NORTHWEST WIND SHEAR
APPEAR (ANALYSIS AT 18KT AT 00Z BY CIMSS) WITH CONVECTION SHIFTED IN
THE EASTERN HALF CIRCLE. THE INTENSITY ASSESSMENT IS IN GOOD
AGREEMENT WITH THIS MORNING PARTIAL ASCAT SWATH.

A SHORT WINDOW OF ENVIRONMENTAL CONDITIONS ENOUGH FAVORABLE TO THE
INTENSIFICATION EXISTING TODAY. NORTHWESTERLY VERTICAL WINDSHEAR
SHOULD BE COMPENSATED BY AN EXCELLENT POLARWARD UPPER LEVEL
DIVERGENCE IN WARM SUBTROPICAL JET ENTRANCE. FROM TONIGHT, THE SYSTEM
IS EXPECTED TO MOVE IN THE VICINITY OF THE SUBTROPICAL JET AND WILL
EXPERIENCE AN INCREASED NORTHWESTERLY SHEAR AND AN INTRUSION OF MID
TROPOSPHERE DRY AIR. FROM TOMORROW AND BEYOND, UNFAVORABLE
ENVIRONMENTAL CONDITIONS ARE EXPECTED LEADING TO THE FILLING UP OF
THE LOW, ASSOCIATED WITH STRONG WINDS IN THE SOUTHERN SECTOR DUE TO
THE GRADIENT EFFECT.

THE CURRENT MOTION IS DRIVEN BY NEAR EQUATORIAL RIDGE LOCATED TO THE
NORTH-EAST AS THE SYSTEM IS LOCATED NORTH OF A WEAKNESS OF THE
SUBTROPICAL RIDGE. AS THE SYSTEM IS EXPECTED TO WEAKEN, THE TRACK
SHOULD TURN WESTWARDS OR SOUTHWESTWARDS WITHIN THE LOW LEVELS
STEERING FLOW. IF THE CURRENT TRACK IS BASED ON A CONSENSUS AVAILABLE
NUMERICAL GUIDANCE, IT SHOULD BE MENTIONED THAT THERE IS A
SIGNIFICANT SPREAD AMONG THE GUIDANCE FROM THE END OF THE DAY IN
RELATION WITH THE WEAKENING PHASE.=

2.C ADDITIONAL INFORMATION:
FT=CI=3.0

OVER THE LAST 6 HOURS, THE CLOUD PATTERN WAS IMPROVED. ALSO, THE
SYSTEM HAS BEEN NAMED AT 0300Z BY THE MAURITIUS METEOROLOGICAL
SERVICES. SINCE CONVECTION HAS REMAINED STRONG WITH THE FORMATION OF
A CURVED BAND. FOR ALL THAT, SIGNS OF VERTICAL NORTHWEST WIND SHEAR
APPEAR (ANALYSIS AT 18KT AT 00Z BY CIMSS) WITH CONVECTION SHIFTED IN
THE EASTERN HALF CIRCLE. THE INTENSITY ASSESSMENT IS IN GOOD
AGREEMENT WITH THIS MORNING PARTIAL ASCAT SWATH.

A SHORT WINDOW OF ENVIRONMENTAL CONDITIONS ENOUGH FAVORABLE TO THE
INTENSIFICATION EXISTING TODAY. NORTHWESTERLY VERTICAL WINDSHEAR
SHOULD BE COMPENSATED BY AN EXCELLENT POLARWARD UPPER LEVEL
DIVERGENCE IN WARM SUBTROPICAL JET ENTRANCE. FROM TONIGHT, THE SYSTEM
IS EXPECTED TO MOVE IN THE VICINITY OF THE SUBTROPICAL JET AND WILL
EXPERIENCE AN INCREASED NORTHWESTERLY SHEAR AND AN INTRUSION OF MID
TROPOSPHERE DRY AIR. FROM TOMORROW AND BEYOND, UNFAVORABLE
ENVIRONMENTAL CONDITIONS ARE EXPECTED LEADING TO THE FILLING UP OF
THE LOW, ASSOCIATED WITH STRONG WINDS IN THE SOUTHERN SECTOR DUE TO
THE GRADIENT EFFECT.

THE CURRENT MOTION IS DRIVEN BY NEAR EQUATORIAL RIDGE LOCATED TO THE
NORTH-EAST AS THE SYSTEM IS LOCATED NORTH OF A WEAKNESS OF THE
SUBTROPICAL RIDGE. AS THE SYSTEM IS EXPECTED TO WEAKEN, THE TRACK
SHOULD TURN WESTWARDS OR SOUTHWESTWARDS WITHIN THE LOW LEVELS
STEERING FLOW. IF THE CURRENT TRACK IS BASED ON A CONSENSUS AVAILABLE
NUMERICAL GUIDANCE, IT SHOULD BE MENTIONED THAT THERE IS A
SIGNIFICANT SPREAD AMONG THE GUIDANCE FROM THE END OF THE DAY IN
RELATION WITH THE WEAKENING PHASE.=

REMARKS:
042100Z POSITION NEAR 16.2S 66.8E.
04FEB20. TROPICAL CYCLONE (TC) 13S (THIRTEEN), LOCATED
APPROXIMATELY 580 NM EAST-NORTHEAST OF PORT LOUIS, MAURITIUS, HAS
TRACKED SOUTHEASTWARD AT 14 KNOTS (KTS) OVER THE PAST SIX HOURS.
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS FLARING
CONVECTION OVERHEAD AND TO THE NORTH OF A LOW LEVEL CIRCULATION
CENTER (LLCC). A DIRECT 041740Z METOP-B ASCAT IMAGE DEPICTS A
CONSOLIDATED LLCC WITH A SWATH OF 35 KT WIND BARBS TO THE
NORTHEAST AND WRAPPING INTO THE LLCC FROM THE EAST. THIS IMAGE
PLACES HIGH CONFIDENCE IN THE INITIAL POSITION AND INTENSITY,
WHICH IS FURTHER SUPPORTED BY DVORAK CURRENT INTENSITY ESTIMATES
OF T2.0-2.5 (30-35 KTS) BY PGTW, KNES, AND FMEE. WIND RADII HAVE
BEEN UPDATED BASED ON THE AFOREMENTIONED ASCAT. LOCATED IN AN
OVERALL FAVORABLE ENVIRONMENT, THE SYSTEM IS EXPERIENCING ROBUST
DUAL CHANNEL OUTFLOW, LOW TO MODERATE (15-20 KT) VERTICAL WIND
SHEAR, AND WARM (29-30 CELSIUS) SEA SURFACE TEMPERATURES (SST).
THIS ENVIRONMENT WILL ALLOW FOR A BRIEF PERIOD OF INTENSIFICATION
TO A PEAK OF 45 KTS BEFORE INCREASING VERTICAL WIND SHEAR VALUES
BEGIN TO LIMIT DEVELOPMENT. TC 13S IS TRACKING ALONG THE SOUTHERN
PERIPHERY OF A NEAR EQUATORIAL RIDGE TO THE NORTH WHICH WILL ACT
AS THE PRIMARY STEERING FEATURE THROUGH TAU 48. AFTER THAT, A
SUBTROPICAL RIDGE (STR) BUILDING TO THE SOUTH AND EAST WILL TURN
TC 13S TO A GENERALLY SOUTHWESTWARD TRACK. CONCURRENTLY,
DECREASING DIVERGENCE ALOFT WILL CAUSE THE SYSTEM TO GRADUALLY
WEAKEN, WITH DISSIPATION OVER WATER EXPECTED BY TAU 96. THE
DYNAMIC MODEL GUIDANCE IS IN FAIR AGREEMENT THROUGH TAU 24.
HOWEVER, DUE TO VARIATIONS IN THE TIMING AND EXTENT OF THE
SOUTHWESTWARD TURN, MODEL SPREAD BEGINS TO INCREASE AFTER TAU 24.
SPECIFICALLY, THE MODEL SOLUTIONS DIVERGE DUE TO VARIATIONS IN THE
TIMING AND STRENGTH OF A PASSING TROUGH TO THE SOUTH. THE GFS
SOLUTION SHOWS A WEAKER TROUGH THAN THE ECMWF SOLUTION, CAUSING
IMPACTS TO THE STR STEERING TC 13S IN THE EXTENDED FORECAST. DUE
TO THESE DIFFERENCES, THERE IS LOW CONFIDENCE IN THE JTWC FORECAST
TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 041800Z IS 15 FEET. NEXT
WARNINGS AT 050900Z AND 052100Z.
