WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: (1) AT 250600Z, TROPICAL STORM 16W (CHABA) WAS LOCATED NEAR 17.4N 130.4E, APPROXIMATELY 555 NM SOUTH-SOUTHEAST OF KADENA AB, OKINAWA, JAPAN, AND HAD TRACKED NORTHWEST-WARD AT 06 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 55 KNOTS GUSTING TO 70 KNOTS. SEE REF A (WTPN32 PGTW 250900) FOR FURTHER DETAILS. (2) NO OTHER TROPICAL CYCLONES. B. TROPICAL DISTURBANCE SUMMARY: (1) AN AREA OF CONVECTION HAS PERSISTED NEAR 22.5N 153.4E, APPROXIMATELY 615 NM NORTHEAST OF SAIPAN. THIS AREA IS THE REMNANT OF TROPICAL DEPRESSION 17W. ANIMATED MULTISPECTRAL IMAGERY SHOWS A FULLY EXPOSED LOW LEVEL CIRCULATION CENTER NORTH OF A SHALLOW CONVECTION THAT HAS WEAKENED OVER THE PAST SIX HOURS. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS SOUTH OF THE SUBTROPICAL RIDGE AXIS TO THE NORTH IN A ZONE OF MODERATE VERTICAL WIND SHEAR. A TROPICAL UPPER TROPOSPHERIC TROUGH (TUTT) CELL TO THE NORTHWEST HAS MOMENTARILY PROVIDED POLEWARD OUTFLOW BUT AS THE TUTT MOVED FURTHER WEST THE OUTFLOW HAS SINCE WANED. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS POOR. (2) NO OTHER SUSPECT AREAS. 2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: NONE. 3.
