1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 99W) PREVIOUSLY LOCATED NEAR 
13.7N 125.2E IS NOW LOCATED NEAR 14.4N 124.7E, APPROXIMATELY 219 NM 
EAST OF MANILA, PHILIPPINES. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
(MSI) DEPICTS A CONSOLIDATING LOWER LEVEL CIRCULATION (LLC) WITH 
BANDING CONVECTION. A 152219Z SSMIS F16 91GHZ MICROWAVE PASS REVEALS 
BROAD, FRAGMENTED BANDING. A RECENT 160106Z ASCAT-B 25KM IMAGE DEPICTS 
A SWATH OF HIGH WINDS IN THE GRADIENT WITH A SUBTROPICAL STEERING RIDGE 
TO THE NORTHEAST OF THE CENTER. ENVIRONMENTAL ANALYSIS INDICATES 
FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW VERTICAL WIND SHEAR (VWS) 
OF 10-15 KNOTS, GOOD EQUATORWARD UPPER-LEVEL OUTFLOW, AND WARM SEA 
SURFACE TEMPERATURES OF 29-30C. DETERMINISTIC AND ENSEMBLE MODELS 
DEPICT INTENSIFICATION WITH A NORTH-NORTHWESTWARD TRACK TOWARD LUZON, 
PHILIPPINES. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS IS UPGRADED TO HIGH. SEE REF A (WTPN21 PGTW 160330)
