WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: (1) AT 300000Z, TYPHOON 16W (CHABA) WAS LOCATED NEAR 32.0N 137.2E, APPROXIMATELY 225 NM SOUTH-SOUTHWEST OF YOKOSUKA, JAPAN, AND HAD TRACKED NORTHEASTWARD AT 19 KNOTS DURING THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 70 KNOTS GUSTING TO 85 KNOTS. SEE REF A (WTPN32 PGTW 300300) FOR FURTHER DETAILS. (2) NO OTHER TROPICAL CYCLONES. B. TROPICAL DISTURBANCE SUMMARY: (1) AN AREA OF CONVECTION HAS PERSISTED NEAR 6.1N 108.6E, APPROXIMATELY 300 NM SOUTH-SOUTHEAST OF HO CHI MINH, VIETNAM. A 300238Z ASCAT PASS SHOWS A DEVELOPING LOW LEVEL CIRCULATION CENTER (LLCC) WITH MODERATE NORTH-TO-NORTH-NORTHEASTERLY FLOW FLANKING THE WESTERN PERIPHERY OF THE CIRCULATION. WINDS AT THE CORE ARE LIGHTER AT 10 TO 15 KNOTS. A MID-LEVEL CIRCULATION CAN ALSO BE SPOTTED IN MULTISPECTRAL ANIMATION, NORTH OF THE SURFACE CIRCULATION DEPICTED IN ASCAT. OVERALL THE CONVECTION IS WEAK AND SHOWS NO IMMINENT SIGNS OF ORGANIZATION. THE DISTURBANCE LIES WITHIN A NARROW CORRIDOR OF LOW TO MODERATE VERTICAL WIND SHEAR. A STRONG UPPER LEVEL RIDGE CENTER OVER THE GULF OF TONKIN IS SUPPRESSING EXPANSION OF THE CONVECTION TO THE NORTH AND HAS RESTRICTED OUTFLOW TO THE WEST. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 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.// +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
