ABPW10 PGTW 160730 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND /SOUTH PACIFIC OCEANS REISSUED/160730Z-170600ZOCT2020// REF/A/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/160651ZOCT2020// AMPN/REF A IS A TROPICAL CYCLONE FORMATION ALERT CANCELLATION.// 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 94W) PREVIOUSLY LOCATED NEAR 15.0N 118.4E IS NOW LOCATED NEAR 16.2N 112.4E, APPROXIMATELY 242 NM EAST OF DANANG, VIETNAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A NEAR FULLY-EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH FLARING DEEP CONVECTION BEING SHEARED TO THE WEST. A 160201Z MHS METOP-B 89GHZ REVEALS LITTLE TO NO ORGANIZED DEEP CONVECTION WITH A SMALL AREA OF DEEP CONVECTION NEAR THE LLCC. A 160046Z METOP-A ASCAT PASS SHOWS A SMALL, WEAK CIRCULATION EMBEDDED IN THE NORTHERN PERIPHERY OF A BROADER, WEAK CIRCULATION. THE ASCAT PASS REVEALS 25 TO 30 KNOT WINDS ON THE NORTHERN SIDE OF 94W WITH SIGNIFICANTLY WEAKER (5 TO 10 KNOT) WINDS TO THE SOUTH. 94W IS CURRENTLY IN A MARGINAL ENVIRONMENT WITH DISORGANIZED UPPER LEVEL OUTFLOW, MODERATE (15 TO 20 KNOT) VERTICAL WIND SHEAR, AND WARM (28 TO 29 CELSIUS) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN FAIR AGREEMENT THAT 94W WILL REMAIN LARGELY STATIONARY FOR THE NEXT COUPLE DAYS WITH SOME SLIGHT CONSOLIDATION, BEFORE CONTINUING WEST, MOVING OVER VIETNAM. 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 DOWNGRADED TO LOW. SEE REF A (WTPN21 PGTW 160700) 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: DOWNGRADED AREA IN PARA 1.B.(1) TO LOW.// NNNN
