FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN 100 NM EITHER SIDE OF A LINE FROM 13.4N 110.9W TO 16.4N 108.2W 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 020000Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 13.8N 110.6W. THE SYSTEM IS MOVING NORTHEASTWARD AT 05 KNOTS. 2. REMARKS: AN AREA OF CONVECTION (INVEST 94E) HAS PERSISTED NEAR 13.8N 110.6W, APPROXIMATELY 338 NM SOUTH OF SOCORRO. ANIMATED ENHANCED INFRARED (AEIR) IMAGERY SHOWS A BROAD LOW LEVEL CIRCULATION (LLC) WITH PERSISTENT DEEP CONVECTION TO THE NORTHEAST. THIS IS SUPPORTED BY A 012112Z AMSR2 89GHZ MICROWAVE IMAGE THAT ALSO REVEALS FORMATIVE BANDING TO THE NORTH OF THE LLC. A 011702Z METOP-B PARTIAL ASCAT PASS SHOWS VERY ELONGATED TROUGHING WITH A SWATH OF 20 TO 25 KNOT WINDS TO THE EAST OF THE LLC. THE UPPER LEVEL ENVIRONMENT IS GENERALLY FAVORABLE WITH VERTICAL WIND SHEAR VALUES OF 10 TO 15 KNOTS AND STRONG DUAL OUTFLOW CHANNELS. REGIONAL SEA SURFACE TEMPERATURES ARE CONDUCIVE FOR DEVELOPMENT AT 28 TO 29 DEGREES CELSIUS. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT THE SYSTEM WILL TRACK GENERALLY NORTHEASTWARD TOWARD THE TIP OF THE BAJA PENINSULA WITH MODERATE INTENSIFICATION. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH. 3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY 030130Z.//NNNN |
