REF B IS A TROPICAL /CYCLONE FORMATION ALERT.// RMKS/ 1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: (1) AT 200000Z, TYPHOON 12W (FANAPI) WAS LOCATED NEAR 23.9N 117.6E, APPROXIMATELY 210 NM EAST-NORTHEAST OF HONG KONG CHINA, AND HAD TRACKED WEST-NORTHWESTARD AT 13 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 65 KNOTS GUSTING TO 80 KNOTS. SEE REF A (WTPN31 PGTW 200300) FOR FURTHER DETAILS. (2) NO OTHER TROPICAL CYCLONES. B. TROPICAL DISTURBANCE SUMMARY: (1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 13.9N 151.2E, IS NOW LOCATED NEAR 18.0N 146.7E, APPROXIMATELY 175 NM NORTH-NORTHEAST OF SAIPAN. RECENT ANIMATED MULTISPECTRAL SATELLITE IMAGERY INDICATES A PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH EXTENSIVE DEEP CONVECTION FLARING ALONG THE EASTERN PERIPHERY. RECENT OBSERVATIONS FROM SAIPAN INDICATE WEAK LOW LEVEL SOUTH-SOUTHWESTERLY FLOW INTO THE SOUTHERN PERIPHERY OF THE LLCC. UPPER LEVEL ANALYSIS REVEALS THE LLCC IS LOCATED BENEATH A STRONG ANTICYCLONE, CAUSING ENHANCED DIFFLUENCE ALOFT. ADDITIONALLY, TROPICAL UPPER TROPOSPHERIC TROUGH (TUTT) CELLS TO THE NORTH AND EAST OF THE SYSTEM ARE INDUCING INCREASED POLEWARD AND EASTWARD OUTFLOW. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS GOOD. SEE REF B (WTPN22 PGTW 200300) FOR FURTHER DETAILS. (2) NO OTHER SUSPECT AREAS. 2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST): A. TROPICAL CYCLONE SUMMARY: NONE. B.
