MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS ","A POORLY ORGANIZED LOW LEVEL CIRCULATION CENTER (LLCC) WITH CYCLING ","OF DEEP CONVECTION SOUTH SOUTH-EAST. A 202355Z ASCAT PASS DEPICTS THE ","STRONGEST WINDS (20-25 KTS) ISOLATED TO THE NORTHWEST. ENVIRONMENTAL ","ANALYSIS FOR THE AREA INDICATES FAVORABLE CONDITIONS WITH LOW ","VERTICAL WIND SHEAR (10-15 KTS) ACCOMPANIED BY WARM (30C) ","SEA SURFACE TEMPERATURES AND MODERATE EQUATORWARD OUTFLOW ALOFT. ","GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 98W WILL CONTINUE NORTH AS ","IT GRADUALLY INTENSIFIES OVER THE NEXT 48 HOURS.
