SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND
/SOUTH PACIFIC OCEANS/120600Z-130600ZMAY2021//
RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 96W) PREVIOUSLY LOCATED 
NEAR 7.4N 131.6E IS NOW LOCATED NEAR 7.6N 131.1E, APPROXIMATELY 210 
NM WEST OF PALAU. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI)  
DEPICTS BROAD LOWER LEVEL TURNING MARGINALLY DECOUPLED FROM A MORE 
DEFINED UPPER LEVEL CIRCULATION. AN 112304Z ASCAT-A PASS REVEALS A 
BROAD LOWER LEVEL CIRUCLATION WITH 15-20KT WINDS IN THE NORTHERN 
PERIPHERY. INVEST 96W IS IN A FAVORABLE ENVIRONMENT WITH VERY WARM 
(30-31C) SEA SURFACE TEMPERATURES, AND NEARLY RADIAL OUTFLOW 
MARGINALLY OFFSET BY MODERATE (10-20KT) VERTICAL WIND SHEAR. GLOBAL 
MODELS PREDICT THAT 96W WILL EXPERIENCE LITTLE TO NO INTENSIFICATION 
AS IT PROPAGATES NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 1006 MB. DUE TO THE FAVORABLE ENVIRONMENT, THE POTENTIAL 
FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE 
NEXT 24 HOURS IS UPGRADED TO MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
