REMARKS:
260900Z POSITION NEAR 28.4S 77.6E.
26JAN20. TROPICAL CYCLONE (TC) 11S (ESAMI), LOCATED APPROXIMATELY
1190 NM EAST-SOUTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED
SOUTHEASTWARD AT 22 KNOTS (KTS) OVER THE PAST SIX HOURS. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) REVEALS A LOW LEVEL CIRCULATION
WITH CONVECTION BEING SHEARED TO THE NORTHEAST. A 260401Z GMI 36 GHZ
MICROWAVE IMAGE DEPICTS A WELL-DEFINED LOW LEVEL CIRCULATION CENTER
(LLCC) WITH CONVECTIVE BANDING WRAPPING IN FROM THE NORTH AND A
FORMATIVE MICROWAVE EYE FEATURE. THE MSI ALONG WITH EXTRAPOLATIONS OF
A PARTIAL 260342Z METOP-A ASCAT PASS AND THE AFOREMENTIONED MICROWAVE
IMAGE LEND GOOD CONFIDENCE IN THE INITIAL POSITION. THE 260342Z ASCAT
DEPICTED 35-40 KT WINDS PRESENT IN THE EASTERN QUADRANT OF THE LLCC,
PLACING GOOD CONFIDENCE IN THE INITIAL INTENSITY OF 40 KTS. TC 11S IS
IN AN OVERALL UNFAVORABLE ENVIRONMENT WITH HIGH (25-30 KT) VERTICAL
WIND SHEAR (VWS), UNFAVORABLE (25-26 CELSIUS) SEA SURFACE TEMPERATURE
(SST), AND MARGINAL OUTFLOW ALOFT. NOTABLY, THE OUTFLOW OF TC 10S HAS
BEEN IMPACTING TC 11S, INHIBITING FURTHER DEVELOPMENT IN THE WESTERN
SEMICIRCLE. TC 11S IS TRACKING ALONG THE PERIPHERY OF WEAK EQUATORIAL
RIDGING TO THE NORTH AND EAST. THROUGH TAU 24, TC 11S WILL TRANSIT
SOUTH-SOUTHEASTWARD, WEAKENING AS VWS CONTINUES TO INCREASE AND SST
COOL BELOW 25 DEGREES CELSIUS. THESE UNFAVORABLE CONDITIONS WILL
CAUSE THE SYSTEM TO BEGIN DISSIPATING AT TAU 24 AS IT BEGINS TO CURVE
SOUTHWESTWARD DUE TO INTERACTION WITH A BUILDING RIDGE TO THE SOUTH.
TC 11S WILL DISSIPATE OVER WATER BY TAU 36 AS IT INTERACTS WITH THE
OUTER PERIPHERY OF TC 10S APPROACHING FROM THE NORTHWEST. NUMERICAL
MODELS ARE IN FAIR AGREEMENT, LENDING GOOD CONFIDENCE TO THE JTWC
FORECAST TRACK WHICH LIES NEAR THE MULTI-MODEL CONSENSUS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 260600Z IS 12 FEET. NEXT WARNINGS AT
262100Z AND 270900Z. REFER TO TROPICAL CYCLONE 10S (DIANE) WARNINGS

AU COURS DES DERNIERES 6H, LA CONVECTION PROFONDE A REPRIS DANS LE
QUADRANT NORD-EST DE LA CIRCULATION EN FIN DE NUIT, MAIS LE SYSTEME
PRESENTE TOUJOURS UNE CONFIGURATION CISAILLEE AVEC LE CENTRE
COMPLETEMENT EXPOSE EN BORDURE OUEST-SUD-OUEST DE LA CONVECTION.

EN TERME DE PREVISION DE TRAJECTOIRE, PAS DE CHANGEMENT MAJEUR :
ESAMI RESTE ATTIRE VERS LE SUD-EST PAR LE PASSAGE D'UN THALWEG DES
MOYENNES LATITUDES AU SUD. LA DISPERSION DES MODELES EST MODEREE.

ESAMI RESTE POUR LE MOMENT EN BORDURE NORD DU JET, SOUMIS A UNE
CONTRAINTE D'OUEST-NORD-OUEST DE 24KT (ESTIMATION CIMSS A 00Z).
CEPENDANT, L'ENERGIE OCEANIQUE EST DEJA LIMITEE ET VIENDRA A MANQUER
AU SUD DE 26S.

AUJOURD'HUI, LE SYSTEME DEVRAIT PASSER PROGRESSIVEMENT SOUS L'AXE DU
JET D'ALTITUDE ET SUBIR UN CISAILLEMENT VERTICAL DE NORD-OUEST DE
PLUS EN PLUS FORT.EN COURS DE JOURNEE, LE SYSTEME EST EGALEMENT PREVU
COMMENCER A INTERAGIR AVEC LA ZONE BAROCLINE ASSOCIA E ET AINSI
COMMENCER A PERDRE SES CARACTA RISTIQUES PUREMENT TROPICAL.
LUNDI, LE SYSTEME EST PREVU SE COMBLER RAPIDEMENT.=

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

IN THE LAST 6 HOURS, DEEP CONVECTION HAS REBUILT AT THE END OF NIGHT,
BUT THE SYSTEM REMAINS SHEARED WITH THE CENTRE COMPLETLY EXPOSED
WEST-SOUTH-WEST TO CONVECTION.

IN TERMS OF TRACK FORECAST, NO MAJOR CHANGE : ESAMI REMAINS ATTRACTED
SOUTH-EASTWARD BY THE PASSAGE OF A MID-LATITUDE TROUGH IN THE SOUTH.
MODEL DISPERSION REMAINS MODERATE.

ESAMI REMAINS ON THE NORTHERN BORDER OF THE JET FOR NOW, WITH A
WEST-SOUTH-WESTERLY SHEAR CONSTRAINT OF 24 KT (CIMSS ESTIMATE AT
00Z). HOWEVER, OCEANIC HEAT CONTENT IS ALREADY LIMITED AND WILL
COMPLETELY DISAPPEAR SOUTH OF 26.

TODAY, THE SYSTEM SHOULD SLIDE UNDER THE UPPER JET AXIS AND
EXPERIENCE A NORTHWESTERLY VERTICAL WINDSHEAR STRONGER AND STRONGER.
THE SYSTEM IS ALSO EXPECTED TO BEGIN TO INTERACT WITH THE ASSOCIATED
BAROCLINIC AREA AND BEGIN TO LOOSE ITS PURELY TROPICAL
CHARACTERISTICS.
FROM MONDAY, THE SYSTEM IS FORECASTED TO FILL UP QUICKLY.=

AU COURS DES DERNIERES 6H, SOUS L'EFFET DE L'AIR SEC, LA
CONFIGURATION NUAGEUSE S'EST DA GRADA E AVEC UNE CONVECTION PROFONDE
QUI S'EST BIEN REDUITE. LA CIRCULATION EST MAINTENANT PARTIELLEMENT
EXPOSA E AVEC UN CENTRE APPARENT.

EN TERME DE PREVISION DE TRAJECTOIRE, PAS DE CHANGEMENT MAJEUR :
ESAMI RESTE ATTIRE VERS L'EST-SUD-EST PUIS LE SUD-EST PAR LE PASSAGE
D'UN THALWEG DES MOYENNES LATITUDES AU SUD. LA DISPERSION DES MODELES
EST MODEREE.

ESAMI RESTE POUR LE MOMENT EN BORDURE NORD DU JET, SOUMIS A UNE
CONTRAINTE D'OUEST DE 17KT (ESTIMATION CIMSS A 18Z). CEPENDANT,
L'ENERGIE OCEANIQUE EST DEJA LIMITEE ET VIENDRA A MANQUER AU SUD DE
26S. AUJOURD'HUI, LE SYSTEME DEVRAIT PASSER PROGRESSIVEMENT SOUS
L'AXE DU JET D'ALTITUDE ET SUBIR UN CISAILLEMENT VERTICAL DE
NORD-OUEST DE PLUS EN PLUS FORT. DANS LA NUIT DE DIMANCHE A LUNDI, LE
SYSTEME EST PREVU COMMENCER A INTERAGIR AVEC LA ZONE BAROCLINE
ASSOCIA E ET AINSI PERDRE SES CARACTA RISTIQUES PUREMENT TROPICAL.
LUNDI, LE SYSTEME EST PREVU SE COMBLER RAPIDEMENT EN SE FONDANT DANS
LA CIRCULATION CYCLONIQUE DU SYSTEME TROPICAL DIANE.=

REMARKS:
252100Z POSITION NEAR 25.9S 74.8E.
25JAN20. TROPICAL CYCLONE (TC) 11S (ESAMI), LOCATED APPROXIMATELY
1011 NM EAST-SOUTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED
SOUTHEASTWARD AT 11 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED (EIR) SATELLITE IMAGERY DEPICTS A LOW LEVEL CIRCULATION
WITH INTENSE CONVECTION SHEARED TO THE NORTHEAST. THE INITIAL
POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON A 251816Z GMI 36GHZ
IMAGE THAT DEPICTS A WELL DEFINED LOW LEVEL CIRCULATION CENTER
(LLCC) WITH SHALLOW BANDS OF CONVECTION IN THE NORTH AND SOUTH
QUADRANTS. THE INITIAL INTENSITY IS ALSO PLACED WITH HIGH CONFIDENCE
HEDGED ABOVE A PGTW DVORAK INTENSITY ESTIMATE OF T2.5 (35 KTS) BASED
ON A 251816Z ASCAT-A DATA THAT REFLECTS 40KT WINDS TO THE EAST OF
THE CIRCULATION. ESAMI IS TRACKING ALONG THE PERIPHERY OF WEAK
EQUATORIAL RIDGING TO THE NORTH AS IT CONTINUES TO TRAVERSE THROUGH
AN INCREASINGLY MARGINAL ENVIRONMENT. MARGINAL (15-20 KTS) VERTICAL
WIND SHEAR (VWS) WILL CONTINUE TO INCREASE, SURPASSING 30 KTS BY TAU
12. ADDITIONALLY, MARGINAL SEA SURFACE TEMPERATURES ARE NOTABLY
COOLER (25-26C) AND WILL CONTINUE TO DROP BELOW 24C BY TAU 24,
HINDERING FURTHER DEVELOPMENT. THESE INCREASINGLY UNFAVORABLE
CONDITIONS WILL CAUSE ESAMI TO BEGIN DISSIPATING AT TAU 36 AS IT
BEGINS TO CURVE SOUTHWESTWARD DUE TO INTERACTION WITH A BUILDING
RIDGE TO THE SOUTH. ESAMI WILL THEN DISSIPATE OVER WATER BY TAU 48
AS IT GETS ABSORBED INTO THE OUTER PERIPHERY OF TC DIANE APPROACHING
FROM THE NORTHWEST (380 NM DISTANCE BETWEEN SYSTEMS AT TAU 48).
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 251800Z IS 12 FEET. NEXT WARNINGS
AT 260900Z AND 262100Z. REFER TO TROPICAL CYCLONE 10S (DIANE)

AU COURS DES DERNIERES 6H, LA CONFIGURATION NUAGEUSE A PEU EVOLUE.
MAIS A LA FAVEUR DU CYCLE DIURNE, LA CONVECTION S'EST RENFORCA E DANS
LE QUADRANT NORD DE LA CIRCULATION.

EN TERME DE PREVISION DE TRAJECTOIRE, PAS DE CHANGEMENT MAJEUR :
ESAMI RESTE ATTIRE VERS L'EST-SUD-EST PUIS LE SUD-EST PAR LE PASSAGE
D'UN THALWEG DES MOYENNES LATITUDES AU SUD. LA DISPERSION DES MODELES
EST MODEREE.

ESAMI RESTE POUR LE MOMENT EN BORDURE NORD DU JET, SOUMIS A UNE
FAIBLE CONTRAINTE D'OUEST DE 12KT (ESTIMATION CIMSS A 12Z).
CEPENDANT, L'ENERGIE OCEANIQUE EST DEJA LIMITEE ET VIENDRA A MANQUER
AU SUD DE 26S. AINSI, AVEC L'AIR SEC OMNIPRA SENT EN MOYENNE
TROPOSPHERE, L'INTENSITE DU SYSTEME DEVRAIT PLAFONNER AUJOURD'HUI.
DIMANCHE, LE SYSTEME DEVRAIT PASSER PROGRESSIVEMENT SOUS L'AXE DU JET
D'ALTITUDE ET SUBIR UN CISAILLEMENT VERTICAL DE NORD-OUEST DE PLUS EN
PLUS FORT. DANS LA NUIT DE DIMANCHE A LUNDI, LE SYSTEME EST PREVU
COMMENCER A INTERAGIR AVEC LA ZONE BAROCLINE ASSOCIA ET AINSI PERDRE
SES CARACTERISTIQUES PUREMENT TROPICAL. LUNDI, LE SYSTEME EST PREVU
SE COMBLER RAPIDEMENT EN SE FONDANT DANS LA CIRCULATION CYCLONIQUE DU

OVER THE LAST 6H, CLOUD PATTERN HAS CHANGED A LITTLE. BUT IN FAVOR OF
THE DIURNAL CYCLE, DEEP CONVECTIVE ACTIVITY HAS STRENGTHENED WITHIN
THE NORTHERN QUADRANT.

IN TERMS OF TRACK FORECAST, NO MAJOR CHANGE : ESAMI REMAINS ATTRACTED
EAST-SOUTH-EASTWARD THEN SOUTH-EASTWARD BY THE PASSAGE OF A
MID-LATITUDE TROUGH IN THE SOUTH. MODEL DISPERSION REMAINS MODERATE.

ESAMI REMAINS ON THE NORTHERN BORDER OF THE JET FOR NOW, WITH A WEAK
WESTERLY SHEAR CONSTRAINT OF 12 KT (CIMSS ESTIMATE AT 12Z). HOWEVER,
OCEANIC HEAT CONTENT IS ALREADY LIMITED AND WILL COMPLETELY DISAPPEAR
SOUTH OF 26. SUNDAY, THE SYSTEM SHOULD SLIDE UNDER THE UPPER JET AXIS
AND EXPERIENCE A NORTHWESTERLY VERTICAL WINDSHEAR STRONGER AND
STRONGER. SUNDAY NIGHT, THE SYSTEM IS EXPECTED TO BEGIN TO INTERACT
WITH THE ASSOCIATED BAROCLINIC AREA AND LOOSE ITS PURELY TROPICAL
CHARACTERISTICS. FROM MONDAY, THE SYSTEM IS FORECASTED TO FILL UP
QUICKLY AS IT MERGES WITH THE DIANE CLOCKWISE CIRCULATION.=

OVER THE LAST 6H, DRY AIR FINALLY REACHED THE CENTER OF THE SYSTEM,
FAVORED BY A MID-LEVEL WESTERLY SHEAR CONSTRAINT. OVER THE LAST SAT
IMAGES, THE LOW-LEVEL CIRCULATION CENTER CLEARLY APPEARS ON THE
SOUTHERN BORDER OF THE CONVECTION, WHICH IS NOW CONCENTRATED IN THE
NORTHERN SEMI-CIRCLE. THE SYSTEM INTENSITY ESTIMATE IS IN AGREEMENT
WITH THE DVORAK ANALYSIS AND AVAILABLE OBJECTIVE ESTIMATES.

IN TERMS OF TRACK FORECAST, NO MAJOR CHANGE : ESAMI REMAINS ATTRACTED
EAST-SOUTH-EASTWARD THEN SOUTH-EASTWARD BY THE PASSAGE OF A
MID-LATITUDE TROUGH IN THE SOUTH. MODEL DISPERSION REMAINS MODERATE.

ESAMI REMAINS ON THE NORTHERN BORDER OF THE JET FOR NOW, WITH A WEAK
WEST-SOUTH-WESTERLY SHEAR CONSTRAINT OF 10 KT (CIMSS ESTIMATE).
HOWEVER, OCEANIC HEAT CONTENT IS ALREADY LIMITED AND WILL COMPLETELY
DISAPPEAR SOUTH OF 26. THUS, WITH THE OMNIPRESENT MID-LEVEL DRY AIR,
THE SYSTEM INTENSITY SHOULD NOT INCREASE SIGNIFICANTLY TODAY. SUNDAY,
THE SYSTEM SHOULD SLIDE UNDER THE UPPER JET AXIS. THE AVAILABLE MODEL
GUIDANCE ALTHOUGH SUGGEST A STATIONARY INTENSITY WITH STILL GALE
WINDS, PROBABLY FUELED BY BAROCLINIC PROCESSES. THIS INDUCES A
MODERATE UNCERTAINTY ON THE INTENSITY FORECAST.
IN THE BEGINNING OF NEXT WEEK, THE RESIDUAL LOW SHOULD MERGE WITH A
FRONTAL LIMIT.=

MULTISPECTRAL SATELLITE IMAGERY DEPICTS A COMPACT AREA OF CONVECTION
OBSCURING THE LOW LEVEL CIRCULATION CENTER (LLCC). BASED ON AN
EXTRAPOLATION OF A 250451Z GMI 36 GHZ MICROWAVE IMAGE ALONG WITH
TIGHTLY-WRAPPING LOW LEVEL BANDING IN MSI, THE INITIAL POSITION IS
PLACED WITH GOOD CONFIDENCE. THE INITIAL INTENSITY IS SET AT 45 KTS
BASED ON A 250402Z PARTIAL METOP-A ASCAT IMAGE REVEALING A SWATH OF
40-45 KT WINDS WITHIN THE EASTERN SEMICIRCLE AND IS SUPPORTED BY
DVORAK CURRENT INTENSITY ESTIMATES OF T3.0 BY PGTW, FMEE, AND KNES.
TC 11S IS TRACKING THROUGH A MODERATELY FAVORABLE ENVIRONMENT FOR
CONTINUED DEVELOPMENT. ENVIRONMENTAL ANALYSIS REVEALS MODERATE (15-20
KTS) VERTICAL WIND SHEAR (VWS), WARM (26-27 CELSIUS) SEA SURFACE
TEMPERATURE (SST), AND ESTABLISHED DIVERGENCE ALOFT. BEING STEERED BY
A NEAR-EQUATORIAL RIDGE TO THE NORTH, TC 11S IS TRACKING EAST-
SOUTHEASTWARD AND IS FORECAST TO MAINTAIN THIS TRACK THROUGH TAU 24.
AFTER THIS, THE SYSTEM WILL TURN TO A SOUTH-SOUTHEASTWARD TRACK
THROUGH TAU 48 WITH THE ALONG-TRACK SPEED SLOWING AS THE STEERING
RIDGE TO THE NORTH BEGINS TO WEAKEN. A STRONG SUBTROPICAL RIDGE TO
THE SOUTH WILL BUILD IN AND TAKE OVER AS THE PRIMARY STEERING FEATURE
FOR TC 11S, RESULTING IN THE SHARP RECURVE TO THE WEST BETWEEN TAU 48
AND 72. THE TIMING AND SPEED OF THIS TRACK CHANGE VARIES BETWEEN THE
GLOBAL MODEL SOLUTIONS. TC 11S WILL GRADUALLY WEAKEN AFTER TAU 36 AS
COOLING SST AND INCREASING VWS (>40 KTS) IMPACT THE SYSTEM, WITH
DISSIPATION OVER WATER BY TAU 96. OVERALL, THERE IS LOW CONFIDENCE IN
THE JTWC FORECAST TRACK DUE TO THE COMPLEX STEERING ENVIRONMENT.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 250600Z IS 13 FEET. NEXT WARNINGS
AT 252100Z AND 260900Z. REFER TO TROPICAL CYCLONE 10S (DIANE)
WARNINGS (WTXS31 PGTW) FOR UPDATES.//

AU COURS DES DERNIERES 6H, L'AIR SEC A NETTEMENT GAGNE PAR L'OUEST ET
A COMMENCE A ROGNER LA STRUCTURE DE PETIT CDO. LES SOMMETS NUAGEUX SE
SONT EGALEMENT RECHAUFFES. LA PASSE ASCAT-A DE 0430Z CE MATIN MONTRE
BIEN LA PRESENCE DE COUP DE VENT 35/40KT SUR UNE LARGE ZONE MAIS
CONCENTREE SUR LE DEMI-CERCLE EST. LES IMAGES MICRO-ONDES WINDSAT DE
0052Z ET GPM DE 0451Z MONTRENT BIEN LA PROGRESSION DE L'AIR SEC SUR
LE DEMI-CERCLE OUEST AU COURS DES DERNIERES HEURES, ALORS QUE LA
CONVECTION RESISTE DANS LE DEMI-CERCLE NORD-EST.

EN TERME DE PREVISION DE TRAJECTOIRE, PAS DE CHANGEMENT MAJEUR :
ESAMI RESTE ATTIRE VERS L'EST-SUD-EST PUIS LE SUD-EST PAR LE PASSAGE
D'UN THALWEG DES MOYENNES LATITUDES AU SUD. LA DISPERSION DES MODELES
EST MODEREE.

ESAMI RESTE POUR LE MOMENT EN BORDURE NORD DU JET, SANS CONTRAINTE
CISAILLEE SIGNIFICATIVE. CEPENDANT, L'ENERGIE OCEANIQUE EST DEJA
LIMITEE ET VIENT A MANQUER AU SUD DE 26S. AINSI, AVEC L'AIR SEC
OMNIPRA SENT EN MOYENNE TROPOSPHERE, L'INTENSITE DU SYSTEME DEVRAIT
PLAFONNER AUJOURD'HUI. DIMANCHE, LE CISAILLEMENT D'OUEST POURRAIT
AUGMENTER SI LE SYSTEME PLONGE SUFFISAMMENT SUD, CE QUI INDUIT UNE
CERTAINE INCERTITUDE SUR LA PREVISION D'INTENSITE.
EN DEBUT DE SEMAINE, LE MINIMUM RESIDUEL DEVRAIT SE FONDRE DANS UNE
LIMITE FRONTALE.=

OVER THE LAST 6H, DRY AIR CLEARLY BEGAN TO WEAR THE CDO AWAY,
INVADING FROM THE WEST. CLOUD TOPS HAVE ALSO SIGNIFICANTLY WARMED.
0430Z ASCAT-A SWATH SHOWED 35/40KT GALE FORCE WINDS OVER A
SIGNIFICANT PORTION OF THE EASTERN SEMI-CIRCLE ONLY. COMPARISON OF
0052Z WINDSAT AND 0451Z GPM MW IMAGES SHOW THE PROGRESSION OF THE DRY
AIR OVER THE WESTERN SEMI-CIRCLE OVER THE LAST HOURS, WHILE
CONVECTION RESISTS IN THE NORTH-EASTERN SEMI-CIRCLE.

IN TERMS OF TRACK FORECAST, NO MAJOR CHANGE : ESAMI REMAINS ATTRACTED
EAST-SOUTH-EASTWARD THEN SOUTH-EASTWARD BY THE PASSAGE OF A
MID-LATITUDE TROUGH IN THE SOUTH. MODEL DISPERSION REMAINS MODERATE.

ESAMI REMAINS ON THE NORTHERN BORDER OF THE JET FOR NOW, WITH NO
SIGNIFICANT SHEAR CONSTRAINT YET. HOWEVER, OCEANIC HEAT CONTENT IS
ALREADY LIMITED AND WILL COMPLETELY DISAPPEAR SOUTH OF 26. THUS, WITH
THE OMNIPRESENT MID-LEVEL DRY AIR, THE SYSTEM INTENSITY SHOULD NOT
INCREASE SIGNIFICANTLY TODAY. SUNDAY, THE WESTERLY SHEAR COULD
INCREASE IF THE SYSTEM GOES SOUTH ENOUGH, WHICH INDUCE A MODERATE
UNCERTAINTY ON THE INTENSITY FORECAST.
IN THE BEGINNING OF NEXT WEEK, THE RESIDUAL LOW SHOULD MERGE WITH A
FRONTAL LIMIT.=

MICRO-ONDES RECENTES DE FIN DE NUIT MONTRENT UNE CONVECTION PROFONDE
S'ORGANISANT EN BANDE INCURVEE DANS LE DEMI-CERCLE EST.
L'EXPLOITATION DES DONNEES A HAUTE RESOLUTION DE L'ASCAT D'HIER SOIR
PERMET DE VALIDER DES VENTS FIABLES A 35/40 KT A CE MOMENT LA.
L'INTENSITE COURANTE A 40 KT SE BASE SUR LA FOURCHETTE HAUTE DES
ESTIMATIONS DVORAK DISPONIBLES (2.0-3.0). ESAMI A DONC ETE BAPTISE A
00Z PAR LE SERVICE METEOROLOGIQUE DE MAURICE.

EN TERME DE PREVISION DE TRAJECTOIRE, PAS DE CHANGEMENT : LE FLUX
D'OUEST EN MOYENNE TROPOSPHERE DIRIGE UNE TRAJECTOIRE ATYPIQUE VERS
L'EST-SUD-EST PUIS LE SUD-EST AU COURS DES PROCHAINES 48H. LES
DIFFERENTES GUIDANCES DISPONIBLES SONT EN BONNE ACCORD SUR CETTE

LES CONDITIONS ENVIRONNEMENTALES SONT ENCORE RELATIVEMENT FAVORABLES
A UNE POURSUITE DE L'INTENSIFICATION MAIS LE POTENTIEL OCEANIQUE EST
EN FAIT LE VRAI PREMIER FACTEUR LIMITANT A COURT TERME. BIEN QUE NON
REFLETEE DANS LA PREVISION, UNE INTENSIFICATION ADDITIONNEL EST
POSSIBLE ENCORE AUJOURD'HUI AVANT UN AFFAIBLISSEMENT GRADUEL PAR

THE CDO CLOUD PATTERN HAS MAINTAINED LAST NIGHT WITH SOME
FLUCTUATIONS ON THE CLOUD TOPS TEMPERATURE. RECENT MW DATA REVEALS
THAT THE DEEP CONVECTION IS ORGANISED IN A CURVED BAND OVER THE
EASTERN SEMI-CIRCLE. HIGH RESOLUTION ASCAT DATA FROM LAST NIGHT
SUGGEST BELIEVABLE 35/40 KT WINDS BY THAT TIME. THE FINAL INTENSITY
IS SET AT 40 KT AT THE UPPER BOUND OF ALL AVAILABLE DVORAK ESTIMATES
THAT RANGE FROM 2.0 TO 3.0. THERFORE, THE SYSTEM WAS NAMED ESAMI BY
THE NATIONAL WEATHER SERVICE OF MAURITIUS.

IN TERMS OF TRACK FORECAST, NO CHANGE : THE WESTERLY FLOW IN THE
MID-TROPISPHERE DIRECTS AN ATYPICAL TRACK TOWARDS EAST-SOUTHEAST
DURING THE NEXT 48 HOURS. THE DIFFERENT GUIDANCES AVAILABLE ARE IN
GOOD AGREEMENT ON THIS TRACK.

ENVIRONMENTAL CONDITIONS ARE STILL RATHER GOOD FOR FURTHER
INTENSIFICATION. IN FACT THE OCEANIC POTENTIAL IS THE VERY FIRST
LIMITING FACTOR AT SHORT RANGE. EVEN IT IS NOT MENTIONNED IN THE
CURRENT FORECAST, SOME ADDITIONAL STRENGTHENING IS POSSIBLE TODAY
BEFORE SOME GRADUAL WEAKENING DUE TO A LACK OF OCEANIC CONTAIN.=

REMARKS:
242100Z POSITION NEAR 23.5S 71.2E.
24JAN20. TROPICAL CYCLONE (TC) 11S (ELEVEN), LOCATED APPROXIMATELY
764 NM EAST-SOUTHEAST OF PORT LOUIS, MAURITIUS, HAS TRACKED EAST-
SOUTHEASTWARD AT 16 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED (EIR) SATELLITE IMAGERY DEPICTS A COMPACT AREA OF DEEP
CONVECTION OBSCURING A RAPIDLY CONSOLIDATING LOW LEVEL CIRCLUATION
CETNER (LLCC). THE INITIAL POSITION AND INTENSITY ARE PLACED WITH
HIGH CONFIDENCE BASED ON TIMELY 1648Z ASCAT-A DATA THAT REVEALS 35
KTS WINDS WRAPPING INTO A WELL DEFINED LLCC. TC 11S IS TRANSITING A
MARGINALLY FAVORABLE ENVIRONMENT FOR FURTHER DEVELOPMENT WITH WARM
(26-27C) SEA SURFACE TEMPERATUES AND ESTABLISHED DIFFLUENCE ALOFT,
OFFSET BY MODERATE (10-15KTS) VERTICAL WIND SHEAR. TC 11S IS
TRACKING SOUTHEASTWARD UNDER THE INFLUENCE OF A NEAR-EQUITORIAL
RIDGE TO THE NORTH. GLOBAL DYNAMICAL MODELS ARE IN GOOD AGREEMENT
THAT TC 11S WILL TRACK SOUTHEASTWARD OVER THE NEXT 72 HOURS AND
BEGIN TO SLOW AS THE PREDOMINANT STEERING RIDGE TO THE NORTH WEAKENS
AND THE SYSTEM BEGINS TO INTERACT WITH RIDGING TO THE SOUTH. AS THE
SYSTEM TRACKS SOUTHEASTWARD IT WILL BEGIN TO DISSIPATE AS IT
EXPERIENCES HIGHER VWS IN EXCESS OF 30 KTS BY TAU 36. BY TAU 72, VWS
WILL INCREASE TO > 40KTS AS THE SYSTEM BEGINS TO TRACK UNDER AN
UPPER LEVEL TROUGH MOVING IN FROM THE SOUTH. THIS INCREASING VWS
ALONG WITH COOLER (<25 C) SST BY TAU 72 WILL CAUSE TC 11S TO BEGIN
DISSPIATING OVER WATER. AT THIS TIME, THE SYSTEM WILL ALSO BEGIN TO
INTERACT WITH THE PERIPERY OF TC 10S TO THE WEST. THIS INTERACTION,
ALONG WITH FORCING BY RIDGING TO THE SOUTH, WILL CAUSE A SHARP
RECURVE TO THE WEST. INCREASED VWS, LOWER SST AND CONVERGENT FLOW
ALOFT DUE TO THE INCOMING TROUGH AND INTERACTION WITH 10S WILL
RESULT IN DISSIPATION OVER WATER BY TAU 96. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 241800Z IS 12 FEET. NEXT WARNINGS AT 250900Z AND 252100Z.
REFER TO TROPICAL CYCLONE 10S (DIANE) WARNINGS (WTXS31 PGTW) FOR SIX-
HOURLY UPDATES.
