WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: (1) AN AREA OF CONVECTION HAS PERSISTED NEAR 18.7N 108.6E, APPROXIMATELY 5 NM WEST OF HAINAN. ANIMATED MULTISPECTRAL IMAGERY AND A 070211Z AMSU MICROWAVE IMAGE SHOW AN EXPOSED AND UNORGANIZED LOW LEVEL CIRCULATION CENTER (LLCC). A 070214Z ASCAT PASS DEPICTS 15 TO 20 KNOT WINDS ALONG THE OUTER WESTERN PERIPHERY OF THE LLCC WITH WEAKER CENTRAL WINDS. ADDITIONALLY, OBSERVATIONS FROM HAINAN ARE INDICATING SEA LEVEL PRESSURES OF 1007 MB AND 12 KNOT SOUTHWESTERLY WINDS. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS LOCATED POLEWARD OF THE SUBTROPICAL RIDGE AXIS IN AN AREA OF HIGH VERTICAL WIND SHEAR (25 TO 30 KNOTS). MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. DUE TO THE UNORGANIZED LLCC, CLOSE PROXIMITY TO LAND, AND HIGH VERTICAL WIND SHEAR, 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.
