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 9.5N 115.5E IS NOW LOCATED NEAR 9.7N 116.0E, APPROXIMATELY 420 NM SOUTHWEST OF MANILA, PHILIPPINES. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS PERSISTENT DEEP CONVECTION OVER A DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC). A 110129Z METOP-A IMAGE SHOWS FORMATIVE CONVECTIVE BANDING OVER THE NORTHERN SEMI-CIRCLE. THE 110129Z ASCAT IMAGE DEPICTS A CLOSED LLCC WITH 15-20 KNOT WEST-NORTHWESTERLY TO NORTH-NORTHWESTERLY WINDS OVER THE WESTERN SEMI-CIRCLE. SURFACE OBSERVATIONS OVER NORTHERN BORNEO INDICATE LIGHT WESTERLY WINDS AND SLP NEAR 1006 MB. UPPER LEVEL ANALYSIS INDICATES A MARGINALLY FAVORABLE ENVIRONMENT CHARACTERIZED BY MODERATE (10-20 KNOTS) VERTICAL WIND SHEAR AND STRONG DIFFLUENT FLOW. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. BASED ON THE DEFINED LLCC, SLP, AND WINDS, 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.// +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
