SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/210600Z-220600ZFEB2024//
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 96P) PREVIOUSLY LOCATED NEAR 
16.8S 170.3W IS NOW LOCATED NEAR 22.1S 169.6W, APPROXIMATELY 184 NM 
SOUTH OF NIUE. ANIMATED PROXYVIS SATELLITE IMAGERY DEPICTS AN ELONGATED, 
WEAKLY-DEFINED LOW-LEVEL CIRCULATION (LLC) EMBEDDED WITHIN A TROUGH, 
WITH STRATOCUMULUS CLOUDS ADVECTING ALONG THE WESTERN SEMICIRCLE. 
SIGNIFICANT DRY, STABLE AIR ASSOCIATED WITH THE STRATOCUMULUS FIELD IS 
HINDERING CONVECTIVE DEVELOPMENT. THE SYSTEM IS LOCATED WITHIN WEAK 
SUBTROPICAL WESTERLY FLOW WITH LOW TO MODERATE VERTICAL WIND SHEAR 
OFFSET BY VIGOROUS POLEWARD OUTFLOW. CONSEQUENTLY, A 2102340Z SSMIS 91 
GHZ MICROWAVE IMAGE INDICATES LIMITED CONVECTIVE BANDING OVER THE 
SOUTHEASTERN QUADANT WITH A POORLY-DEFINED CENTER. GLOBAL MODELS REVEAL 
AN EAST-SOUTHEASTWARD TO SOUTHEASTWARD TRACK OVER THE NEXT TWO DAYS, 
WITH GRADIENT-INDUCED WINDS OF 25-30 KNOTS OVER THE SOUTHERN SEMICIRCLE. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 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 REMAINS LOW.
      (2) THE AREA OF CONVECTION (INVEST 97P) PREVIOUSLY LOCATED NEAR 
18.9S 174.0E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE DEVELOPMENT 
OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
      (3) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
