1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
160 NM EITHER SIDE OF A LINE FROM 13.9N 102.3W TO 20.2N 109.1W
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 20 TO 25 KNOTS. METSAT
IMAGERY AT 271800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 15.0N 102.9W. THE SYSTEM IS MOVING NORTHWARD AT 12 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 13.8N
102.8W IS NOW LOCATED NEAR 15.0N 102.9W, APPROXIMATELY 250 NM SOUTH-
SOUTHEAST OF MANZANILLO, MEXICO. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY REVEALS DEEPENING CONVECTION AROUND A CONSOLIDATING AND
QUICKLY IMPROVING LOW LEVEL CIRCULATION CENTER. A 271657Z ASCAT PASS
ADDITIONALLY SHOWS IMPROVED ORGANIZATION AS THE LLCC HAS BECOME MORE
DEFINED AND 20 KNOT WINDS HAVE BECOME ALMOST COMPLETELY WRAPPED
AROUND THE LLCC. UPPER-LEVEL ANALYSIS REVEALS THE SYSTEM IS SOUTH OF
THE SUBTROPICAL RIDGE AXIS WITH DIFFLUENT EASTERLY OUTFLOW AND LOW
(05-10 KNOTS) VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH. |
