REF C IS A TROPICAL CYCLONE FORMATION ALERT.// RMKS/ 1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: (1) AT 22AUG26 0000Z, TYPHOON 17W (SAUDEL) WAS LOCATED NEAR 17.9N 146.5E, APPROXIMATELY 167 NM NORTH-NORTHEAST OF SAIPAN, AND HAD TRACKED NORTHWESTWARD AT 11 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 85 KNOTS GUSTING TO 105 KNOTS. SEE REF A (WTPN31 PGTW 220300) FOR FURTHER DETAILS. (2) AT 22AUG26 0000Z, TROPICAL STORM 18W (EIGHTEEN) WAS LOCATED NEAR 21.1N 108.7E, APPROXIMATELY 157 NM EAST OF HANOI, VIETNAM, AND HAD TRACKED NORTHWESTWARD AT 01 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45 KNOTS. SEE REF B (WTPN32 PGTW 220300) FOR FURTHER DETAILS. (3) NO OTHER TROPICAL CYCLONES. B. TROPICAL DISTURBANCE SUMMARY: (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED NEAR 26.5N 123.7E IS NOW LOCATED NEAR 26.7N 123.2E, APPROXIMATELY 142 NM NORTHEAST OF TAIPEI. THE SYSTEM IS CURRENTLY CLASSIFIED AS A MONSOON DEPRESSION, GENERALLY CHARACTERIZED AS A LARGE CYCLONIC CIRCULATION, GREATER THAN 600 NM DIAMETER, WITH ENHANCED WINDS OVER THE SOUTHERN PERIPHERY AND A WEAK CORE OF LIGHT WINDS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A BROAD CIRCULATION PARTIALLY OBSCURED BY CONVECTION BUILDING IN THE SOUTHEASTERN PERIPHERY OF THE CIRCULATION. ENVIRONMENTAL ANALYSIS REVEALS MOSTLY CONDUCIVE CONDITIONS FOR DEVELOPMENT WITH LOW TO MODERATE (15 TO 20 KTS) VERTICAL WIND SHEAR, WARM SEA SURFACE TEMPERATURES (28 TO 29 C), AND GOOD UPPER-LEVEL OUTFLOW. GLOBAL MODELS INDICATE THAT THE BROAD CIRCULATION WILL STRUGGLE TO CONSOLIDATE INTO A TROPICAL CYCLONE AND ENSEMBLE MODELS DO NOT DEVELOP IT INTO TROPICAL CYCLONE STRENGTH IN THE NEXT 24-36 HOURS. FOR HAZARDS AND WARNINGS, REFERENCE THE FLEET WEATHER CENTER SAN DIEGO HIGH WINDS AND SEAS PRODUCT OR REFER TO LOCAL WMO DESIGNATED FORECAST AUTHORITY. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 27 TO 32 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 REMAINS LOW. (2) THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED NEAR 10.2N 136.6E IS NOW LOCATED NEAR 11.2N 135.9E, APPROXIMATELY 170 NM NORTHWEST OF YAP. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A LOW-LEVEL CIRCULATION (LLC) ALONG A TROUGH WITH FLARING CONVECTION OVER SOUTHWESTERN PERIPHERY OF THE CIRCULATION. ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW TO MODERATE VERTICAL WIND SHEAR (15 TO 20KTS), WARM SEA SURFACE TEMPERATURES (29 TO 30 C), AND GOOD EQUATORWARD UPPER-LEVEL OUTFLOW. GLOBAL DETERMINISTIC MODELS BRIEFLY DEVELOP 97W, BUT IT QUICKLY GETS PULLED INTO THE FLOW OF TYPHOON 17W. ENSEMBLE MODELS ALSO SHOW THE QUICK DEVELOPMENT OF 97W AND A GENERAL NORTHERN TRACK OVER THE NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 17 TO 22 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 UPGRADED TO HIGH. SEE REF C (WTPN21 PGTW 220800) FOR FURTHER DETAILS. (3) 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: JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA. 1.B.(2) TO HIGH.// NNNN
