ABPW10 PGTW 111130 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH PACIFIC OCEANS REISSUED/111130Z-120600ZJUN2021// REF/A/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/111121ZJUN2021// NARR/REF A IS A TROPICAL CYCLONE FORMATION ALERT.// 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 92W) PREVIOUSLY LOCATED NEAR 17.9N 113.4E IS NOW LOCATED NEAR 18.0N 112.2E, APPROXIMATELY 282 NM SOUTH-SOUTHWEST OF HONG KONG. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 110820Z SSMIS 91 GHZ MICROWAVE IMAGE REVEAL A MONSOON DEPRESSION, BUT CONVECTIVE BANDS PREVIOUSLY DISPLACED NEARLY 100NM ARE NOW DEEPENING AND CONSOLIDATING AROUND THE SYSTEM CENTER. THE SYSTEM STILL EXISTS UNDER A MARGINALLY FAVORABLE ENVIRONMENT WITH LOW TO MODERATE VERTICAL WIND SHEAR (VWS) (10-20 KTS) OFFSET BY A LACK OF DIVERGENCE ALOFT. 92W REMAINS IN A FAVORABLE AREA OF WARM SEA SURFACE TEMPERATURES (SST) (30-31C). GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 92W WILL CONTINUE DEVELOPING ALONG ITS WEST-NORTHWESTWARD TRACK AND INTENSIFIES PRIOR TO MOVING OVER HAINAN ISLAND. AFTER A BRIEF PERIOD OF WEAKENING DUE TO FRICTIONAL EFFECTS AS 92W PASSES OVER HAINAN ISLAND, 92W WILL RE- INTENSIFY WHEN IT ENTERS AN AREA OF EVEN WARMER WATERS AND LOWER VWS OVER THE GULF OF TONKIN. FURTHERMORE, AN UPPER-LEVEL ANTICYCLONE TO THE NORTH WILL RETROGRADE EASTWARD AND IMPROVE OUTFLOW ALLOWING FOR FURTHER INTENSIFICATION. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO HIGH. SEE REF A (WTPN21 PGTW 111130) FOR FURTHER DETAILS. (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. 3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA. 1.B.(1) TO HIGH.// NNNN
