由於已接觸到陸地,故JTWC降評為Low
(1) THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED NEAR
12.9N 127.1E IS NOW LOCATED NEAR 13.2N 124.6E, APPROXIMATELY 50 NM
EAST OF LEGAZPI, PHILIPPINES. ANIMATED ENHANCED INFRARED (EIR)
SATELLITE IMAGERY AND AN 112022Z SSMIS 91 GHZ MICROWAVE IMAGE DEPICT A
PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH DEEP
CONVECTION DISPLACED TO THE NORTHWEST. DESPITE HAVING GOOD POLEWARD
OUTFLOW, 90W IS IN AN UNFAVORABLE ENVIRONMENT DUE TO LAND INTERACTION,
LOW TO MODERATE (10-15 KTS) VERTICAL WIND SHEAR (VWS), AND WARM (27-28
C) SEA SURFACE TEMPERATURES (SST). GLOBAL MODELS AGREE THAT INVEST 90W
WILL TRACK WEST-NORTHWESTWARD AND EVENTUALLY DISSIPATE OVER THE COURSE
OF THE NEXT 24-48 HOURS, DUE TO AN INCREASE IN VWS, LAND INTERACTION
AND COPIOUS AMOUNTS OF DRY AIR ENTRAINMENT BEING INTRODUCED FROM THE
NORTHEAST. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 17 TO 23
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN
THE NEXT 24 HOURS IS DOWNGRADED TO LOW.
