WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: (1) AT 301200Z, EXTRATROPICAL CYCLONE 16W (CHABA) WAS LOCATED NEAR 35.3N 142.2E, APPROXIMATELY 125 NM EAST OF TOKYO, JAPAN, AND HAD TRACKED NORTHEASTWARD AT 31 KNOTS DURING THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS GUSTING TO 55 KNOTS. SEE REF A (WTPN32 PGTW 301500) FOR THE FINAL WARNING ON THIS SYSTEM. (2) NO OTHER TROPICAL CYCLONES. B. TROPICAL DISTURBANCE SUMMARY: (1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 6.1N 108.6E, IS NOW LOCATED NEAR 4.5N 108.9E, APPROXIMATELY 400 NM SOUTH- SOUTHEAST OF HO CHI MINH, VIETNAM. ANIMATED INFRARED SATELLITE IMAGERY AND A 301808Z AMSU IMAGE DEPICT DISORGANIZED CONVECTION AND WEAK CONVECTIVE BANDING OVER THE WESTERN SEMI-CIRCLE. A 301343Z ASCAT IMAGE SHOWS A DEFINED LOW LEVEL CIRCULATION CENTER (LLCC) WITH LIGHTER WINDS AT THE CENTER, AROUND 10 TO 15 KNOTS, WITH 15 TO 20 KNOT WINDS AROUND THE PERIPHERY. THE MAJORITY OF THE CONVECTION IS LOCATED TO THE WEST OF THE SYSTEM AND IS DISORGANIZED DUE TO MODERATE NORTHEASTERLY VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO FAIR. (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. JUSTIFICATION FOR REISSUE: UPDATED PARA 1.A.(1) DUE TO FINAL WARNING FOR 16W (CHABA) AND UPGRADED AREA IN PARA 1.B.(1) TO FAIR.// +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
