REMARKS: THIS CANCELS REF A. THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 14.8N 107.7W IS NOW LOCATED NEAR 16.2N 106.1W, APPROXIMATELY 195 NM SOUTH-SOUTHWEST OF MANZANILLO, MEXICO. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 270458Z ASCAT PASS DEPICT A WEAK (10 TO 15 KNOT) EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH WEAK CONVECTION FLARING ALONG THE NORTHWESTERN PERIPHERY. UPPER LEVEL ANALYSIS REVEALS THAT OVER THE PAST 24 HOURS INCREASED EASTERLY VERTICAL WIND SHEAR, ASSOCIATED WITH AN ANTICYCLONE OVER SOUTHERN MEXICO, HAS HINDERED FURTHER DEVELOPMENT OF THE LLCC. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. DUE TO THE UNFAVORABLE UPPER LEVEL ENVIRONMENT, THE SYSTEM IS NO LONGER EXPECTED TO DEVELOP INTO 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.
