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 17.0N 108.8E IS NOW RELOCATED TO 17.0N 108.8E, APPROXIMATELY 95NM EAST-NORTHEAST OF HUE CITY, VIETNAM. RECENT ANIMATED INFRARED SATELLITE IMAGERY SHOWS A RAPIDLY CONSOLIDATING AREA OF DEEP CONVECTION. A 041857Z AMSU-B MICROWAVE IMAGE SHOWS A COMMA-SHAPED BAND FEEDING INTO WHAT IS LIKELY A DEVELOPING LOW LEVEL CIRCULATION CENTER (LLCC). AN EARLIER ASCAT VERIFIES A LARGE CYCLONIC WIND FIELD WITH WINDS APPROACHING GALE FORCE IN THE NORTHEASTERN QUADRANT AS NORTHEASTERLY FLOW MOVING OFF OF EASTERN CHINA CONVERGES INTO THE DISTURBANCE. HOWEVER, THE LOCATION OF THE LLCC IS UNCERTAIN. VIGOROUS POLEWARD DIFFLUENCE AND LOW TO MODERATE VERTICAL WIND SHEAR IS HELPING TO FUEL THE DEEP CONVECTION. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED AT 1002 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO GOOD. 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: UPGRADED AREA IN PARA 1.B(1) TO GOOD.// +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
