"ABPW10 PGTW 060600\r\nMSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//\r\nSUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH \r\nPACIFIC OCEANS/060600Z-070600ZJUN2026//\r\nRMKS/\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE.\r\n   C. SUBTROPICAL SYSTEM SUMMARY:\r\n      (1) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED NEAR \r\n22.2N 120.2E IS NOW LOCATED NEAR 25.4N 123.1E, APPROXIMATELY 260 NM \r\nWEST-SOUTHWEST OF KADENA, JAPAN. THE SYSTEM IS CURRENTLY CLASSIFIED AS A \r\nSUBTROPICAL DEPRESSION, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL \r\nAND MIDLATITUDE CYCLONE FEATURES. ANIMATED MULTISPECTRAL SATELLITE \r\nIMAGERY (MSI) DEPICTS A WEAK, DISORGANIZED ROTATION MOVING JUST SOUTH OF \r\nTHE MAI-YU/BAIU BOUNDARY CURRENTLY DRAPED ACROSS THE EAST CHINA SEA. 91W \r\nIS FORECASTED TO CONTINUE MOVING RAPIDLY NORTH NORTH-EASTWARD INTO THE \r\nEAST CHINA SEA. ENVIRONMENTAL ANALYSIS FOR THE AREA INDICATES MARGINALLY \r\nFAVORABLE CONDITIONS FOR INTENSIFICATION WITH LOW VERTICAL WIND SHEAR \r\n(10-15 KNOTS), WARM (26-27 C) SEA SURFACE TEMPERATURES (SST), AND GOOD \r\nPOLEWARD OUTFLOW ALOFT. THE SYSTEM TRANSITS NORTHEASTWARD IT WILL \r\nENCOUNTER SIGNIFICANTLY COOLER SSTS SURROUNDING THE KUROSHIO CURRENT, AS \r\nWELL AS INCREASED TEMPERATURE ADVECTION. DETERMINISTIC GUIDANCE SHOWS \r\n91W REACHING PEAK INTENSITY OVER THE NEXT 18 HOURS AS IT PASSES WEST OF \r\nOKINAWA. THE WIND FIELD IS FORECAST TO EXPAND AS IT MOVES THROUGH THE \r\nEAST CHINA SEA, WITH THE HIGHEST WINDS BEING LOCATED IN THE EASTERN \r\nHEMISPHERE OF THE CIRCULATION. MAXIMUM SUSTAINED SURFACE WINDS ARE \r\nESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO \r\nBE NEAR 1002 MB. FOR HAZARDS AND WARNINGS, REFERENCE THE FLEET WEATHER \r\nCENTER SAN DIEGO HIGH WINDS AND SEAS PRODUCT OR REFER TO LOCAL WMO \r\nDESIGNATED FORECAST AUTHORITY. THE POTENTIAL FOR THE DEVELOPMENT OF A \r\nSIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.\r\n      (2) NO OTHER SUBTROPICAL SYSTEMS.\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE.\r\n   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//"
