WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: (1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 4.4N 109.5E IS NOW LOCATED NEAR 4.9N 107.9E, APPROXIMATELY 345 NM WEST OF BRUNEI. RECENT ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS AN ILL-DEFINED LOW LEVEL CIRCULATION WITH SHALLOW, DISORGANIZED CONVECTION. A 271344Z ASCAT PASS SHOWS A WEAK 10-15 KNOT CIRCULATION CENTER. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS EQUATORWARD OF THE SUBTROPICAL RIDGE AXIS IN AN AREA OF MODERATE TO HIGH EASTERLY VERTICAL WIND SHEAR AND WEAK DIVERGENCE ALOFT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THESE ARE SUPPORTED BY NEARBY SURFACE OBSERVATIONS. DUE TO A LACK OF CONVECTIVE ORGANIZATION AND UPPER LEVEL SUPPORT, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS 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.
