PACIFIC OCEANS/100600Z-110600ZMAR2023//
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) THE AREA OF CONVECTION (INVEST 99P) PREVIOUSLY LOCATED NEAR 
19.2S 168.8W IS NOW LOCATED NEAR 19.4S 167.1W, APPROXIMATELY 161 NM EAST 
OF NIUE. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) AND A 0100041Z 
AMSR2 GW1 89GHZ MICROWAVE IMAGE REVEALS A FULLY OBSCURED LLC WITH 
BUILDING CONVECTION OVERHEAD AND TO THE SOUTH. A PARTIAL 092103Z ASCAT-B 
PASS REVEALED A LARGE SWATH OF 15-20 KNOT WIND FIELDS ALONG THE WESTERN 
EDGES AND SMALLER FIELDS OF 25-30 KNOTS NEAR THE LLCC. INVEST 99P 
CONTINUES TO BE DEEPLY EMBEDDED WITHIN THE SPCZ, AND ENVIRONMENTAL 
CONDITIONS ARE FAVORABLE WITH WARM (27-28C) SEA SURFACE TEMPERATURES, 
EXCELLENT UPPER LEVEL POLEWARD OUTFLOW AND LOW (05-10KT) VWS. GLOBAL 
MODELS ARE IN GENERAL AGREEMENT THAT 99P WILL GRADUALLY DEVELOP AND 
TRACK SOUTHEASTWARD INTO A TROPICAL CYCLONE OVER THE NEXT 12 TO 24 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 27 TO 32 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1001 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS IS HIGH.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
