   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 17FEB20 1200Z, TROPICAL CYCLONE 16S (GABEKILE) WAS 
LOCATED NEAR 20.3S 75.4E, APPROXIMATELY 810 NM SOUTH-SOUTHEAST OF 
DIEGO GARCIA, AND HAD TRACKED SOUTHEASTWARD AT 01 KNOT (KT) OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 
KNOTS GUSTING TO 55 KNOTS. SEE REF A (WTXS32 PGTW 171500) FOR

SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND
/SOUTH PACIFIC OCEANS REISSUED/180030Z-180600ZFEB2020//
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 10.7S 177.3W IS NOW LOCATED NEAR 11.0S 176.5W, APPROXIMATELY 
382 NM WEST-NORTHWEST OF PAGO PAGO AMERICAN SAMOA. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY AND A 170946Z METOP-B 89GHZ MICROWAVE 
IMAGE DEPICT AN EXTENSIVE, ELONGATED AREA OF FRAGMENTED CONVECTION 
EXTENDING NORTHWEST TO SOUTHEAST WITH MULTIPLE EMBEDDED, WEAK LOW 
LEVEL CIRCULATIONS. INVEST 96P IS EXPERIENCING GOOD POLEWARD 
OUTFLOW, WARM (29-30C) SEA SURFACE TEMPERATURES, AND LOW (<15KTS) 
VERTICAL WIND SHEAR. GLOBAL MODELS AGREE THAT SEVERAL OF THOSE 
EMBEDDED CIRCULATIONS MAY GRADUALLY CONSOLIDATE AND INTENSIFY AS 
THEY TRACK SOUTHEASTWARD. INVEST 96P IS PLACED IN A LIKELY REGION 
FOR ONE OF THOSE CIRCULATIONS TO CONSOLIDATE. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL 
PRESSURE IS ESTIMATED TO BE NEAR 998 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS IS MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93P) PREVIOUSLY LOCATED 
NEAR 15.6S 170.7W IS NOW LOCATED NEAR 19.1S 167.1W, APPROXIMATELY 
352 NM SOUTHEAST OF PAGO PAGO AMERICAN SAMOA. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY DEPICTS AN ELONGATED AREA OF CIRCULATION 
WITH POCKETS OF DEEP CONVECTION EXTENDING FROM THE NORTHWEST TO THE 
SOUTHEAST. A 171739Z SSMIS 91GHZ MICROWAVE IMAGE DEPICTS A DEFINED, 
BROAD LOW LEVEL CIRCULATION CENTER (LLCC). A 172053Z ASCAT-B SHOWS 
STRONG (45-50 KT) ASYMMETRIC WINDS ON THE NORTHEAST SIDE OF THE LLCC 
WITH MODERATE (20-25 KT) WINDS ON THE SOUTHWEST SIDE. ENVIRONMENTAL 
ANALYSIS INDICATES THE SYSTEM IS EXPERIENCING GOOD EQUATORWARD AND 
POLEWARD OUTFLOW ALOFT, WARM (27-28C) SEA SURFACE TEMPERATURES, AND 
VERY HIGH (40-50 KTS) VERTICAL, IN-PHASE, WIND SHEAR. GLOBAL MODELS 
AGREE THE LLCC WILL CONTINUE TO TRACK SOUTHEASTWARD AS A SUBTROPICAL 
CYCLONE. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 30 TO 35 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 994 MB. 
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
      (2) NO OTHER SUBTROPICAL SYSTEMS.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.(C).1 TO 
MEDIUM.//

WWPS21 NFFN 172100
Tropical Disturbance Summary For area Equator to 25S, 160E to 120W
ISSUED FROM RSMC NADI Feb 172337 UTC.

TROPICAL DISTURBANCE 07F CENTRE 1000HPA WAS ANALYSED NEAR 12.2S
178.8E AT 172100UTC. POSITION POOR BASED ON HIMAWARI-8 VIS AND EIR
IMAGERY AND PERIPHERAL SURFACE REPORTS. TD07F SLOW MOVING.

DEEP CONVECTION LIES TO THE NORTH OF THE SUPPOSED LLCC WITH POOR
ORGANISATION. SYSTEM LIES UNDER AN UPPER DIVERGENT AREA IN A LOW
SHEARED ENVIRONMENT. CYCLONIC CIRCULATION EXTENDS UP TO 500HPA. SST
AROUND 30 DEGREES CELSIUS.

GLOBAL MODELS HAVE PICKED UP THE SYSTEM AND MOVE IT SOUTHEASTWARDS
WITH GRADUAL INTENSIFICATION.

THE POTENTIAL FOR THIS SYSTEM TO DEVELOP INTO A CYCLONE IN THE NEXT
24 TO 48 HOURS IS LOW TO MODERATE.
 
*********************************************************************

TROPICAL DISTURBANCE 08F CENTRE 998HPA WAS ANALYSED NEAR 21.3S 166.3W
AT 172100UTC. POSITION FAIR BASED ON HIMAWARI-8 VIS AND EIR IMAGERY
AND PERIPHERAL SURFACE REPORTS. TD08F MOVING SOUTH-SOUTHEAST AT 13
KNOTS.

DEEP CONVECTION LIES TO THE SOUTHEAST OF THE PARTIALLY EXPOSED LLCC.
ORGANISATION REMAINS POOR. SYSTEM LIES JUST TO EAST OF AN UPPER
TROUGH IN A HIGH SHEARED ENVIRONMENT. CYCLONIC CIRCULATION EXTENDS UP
TO 500HPA. SST AROUND 29 DEGREES CELSIUS.

THE POTENTIAL FOR THIS SYSTEM TO DEVELOP INTO A CYCLONE IN THE NEXT
24 TO 48 HOURS IS LOW.

NO OTHER SIGNIFICANT TROPICAL DISTURBANCE ANALYSED OR FORECAST IN THE
