PACIFIC OCEANS/250600Z-260600ZFEB2024//
RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   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:
      (1) AN AREA OF CONVECTION (INVEST 98P) HAS PERSISTED NEAR 15.1S 
171.3E, APPROXIMATELY 232 NM NORTHEAST OF PORT VILA, VANUATU. ANIMATED 
VISIBLE SATELLITE IMAGERY AND A 250219Z AMSR2 36 GHZ MICROWAVE IMAGE 
SHOWS A BROAD AND DISORGANIZED LOW-LEVEL CIRCULATION (LLC) WITH THE 
MAJORITY OF CONVECTION LOCATED ALONG THE EASTERN PERIPHERY. A 242212Z 
PARTIAL ASCAT-C IMAGE REVEALS AN ELONGATED CIRCULATION WITH 15-20 KNOT 
WINDS DISPLACED ALONG THE NORTHEASTERN AND SOUTHERN QUADRANTS OF THE 
SYSTEM. THE CIMSS UPPER-LEVEL WINDS IMAGE DEPICTS A POINT SOURCE TO THE 
SOUTHEAST WITH DIFFLUENT EAST-SOUTHEASTERLY FLOW AND ASSOCIATED MODERATE 
TO STRONG VERTICAL WIND SHEAR (20-25 KTS). THERE IS CURRENTLY AN 
EXTENSIVE SWATH OF DRY AIR ALIGNED ALONG THE SOUTHERN SEMICIRCLE OF THE 
SYSTEM, ENTRAINING INTO THE MID-LEVELS OF THE LLC. GLOBAL MODELS 
INDICATE MINIMAL DEVELOPMENT WITH A GRADUAL MOISTENING OF THE CORE AS IT 
TRACKS SLOWLY SOUTH-SOUTHEASTWARD OVER THE NEXT TWO DAYS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
IS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
