REMARKS: THIS CANCELS REF A. THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 13.6N 156.4W IS NOW LOCATED NEAR 13.7N 158.5W, APPROXIMATELY 415 NM SOUTH-SOUTHWEST OF HILO. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 232352Z AMSU MICROWAVE IMAGE SHOW THE LOW LEVEL CIRCULATION CENTER (LLCC) HAS BECOME UNORGANIZED WITH DECREASED DEEP CONVECTION. A 232038Z ASCAT PASS DEPICTS A WEAK LLCC IN AN AREA OF TROUGHING. UPPER LEVEL ANALYSIS INDICATES AN UPPER LEVEL TROUGH TO THE NORTH CAUSING SUBSIDENCE WITH INCREASED VERTICAL WIND SHEAR, MAKING THE AREA UNFAVORABLE FOR DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1010 MB. DUE TO THE LACK OF DEEP CONVECTION AND THE UNORGANIZED LLCC, THE SYSTEM HAS DISSIPATED AND IS NO LONGER CONSIDERED SUSPECT FOR DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS.// +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
