TROPICAL DEPRESSION (TD) 18W, LOCATED APPROXIMATELY 265NM SOUTHEAST OF HUE CITY, VIETNAM, HAS TRACKED NORTHWESTWARD AT 04 KNOTS DURING THE PAST SIX HOURS. ANIMATED MULTISPECTRAL IMAGERY INDICATES CONVECTION HAS PERSISTED AND CONSOLIDATED NEAR THE LOW LEVEL CIRCULATION CENTER (LLCC) DURING THE PAST SIX HOURS. A 130228Z TRMM 37 GHZ MICROWAVE IMAGE INDICATES THAT THE MAJORITY OF DEEP CONVECTION REMAINS SHEARED OVER THE EASTERN HALF OF THE LLCC. A 130248Z PARTIAL ASCAT IMAGE INDICATES 20-25 KNOT NORTHEASTERLY WINDS TO THE NORTHWEST OF THE LLCC. ANIMATED WATER VAPOR IMAGERY SHOWS THAT ALTHOUGH A WELL-DEVELOPED POLEWARD OUTFLOW CHANNEL EXISTS TO THE NORTHEAST, OUTFLOW IS INHIBITED ON THE WEST SIDE DUE TO THE APPROACH OF AN UPPER LEVEL TROUGH. THE CURRENT INTENSITY IS BASED ON A DVORAK ESTIMATE OF 25 KNOTS FROM PGTW AND IS CONFIRMED BY THE RECENT ASCAT DATA. TD 18W IS TRACKING SLOWLY NORTHWESTWARD ALONG THE WESTERN PERIPHERY OF THE LOW-LEVEL SUBTROPICAL RIDGE IN AN AREA OF MODERATE VERTICAL WINDSHEAR. AVAILABLE DYNAMIC AIDS, ALTHOUGH LIMITED, SUPPORT THIS FORECAST TRACK AND INDICATE THE SYSTEM WILL MAKE LANDFALL OVER VIETNAM AND DISSIPATE WITHIN THE NEXT 24 HOURS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 130600Z IS 10 FEET. NEXT WARNINGS AT 131500Z, 132100Z AND 140300Z.// +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
