JTWC 21/18Z評級Low,對流有增強趨勢
(1) AN AREA OF CONVECTION (INVEST 93W) HAS PERSISTED NEAR 4.8N
137.7E, APPROXIMATELY 238 NM SOUTHEAST OF PALAU. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY AND A 210432Z ATMS NPP 165.5 GHZ IMAGE DEPICT
A BROAD AREA OF TURNING MOVING INTO A FAVORABLE ENVIRONMENT FOR
DEVELOPMENT, WITH CONDUCIVE SEA SURFACE TEMPERATURES (29-30C) AND LOW
VERTICAL WIND SHEAR (10-15KTS). MODERATE TO STRONG POLEWARD OUTFLOW
ALOFT, ENHANCED BY THE FLOW ASSOCIATED WITH AN UPPER-LEVEL TROUGH TO THE
WEST, WILL ALSO SUPPORT THE SYSTEM AS IT MOVES INTO THE PHILIPPINE SEA
OVER THE NEXT FEW DAYS. GLOBAL DETERMINISTIC AND ENSEMBLE MODELS ARE IN
GOOD AGREEMENT THAT 93W WILL TRACK NORTHWESTWARD WITH SLIGHT
INTENSIFICATION OVER THE NEXT 24 HOURS, FOLLOWED BY STEADY
INTENSIFICATION THEREAFTER. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 13 TO 17 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 LOW.
