WITHIN THE ","LAST 24 HOURS, THE STRONGEST TURNING IS NEAR THE SOUTHEASTWARD SIDE OF ","THE LLCC BASED ON EARLIER SCATTEROMETER DATA. ENVIRONMENTAL ANALYSIS ","REVEALS FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW VERTICAL WIND ","SHEAR (15 KNOTS OR LESS), GOOD POLEWARD UPPER-LEVEL OUTFLOW ALOFT, AND ","WARM SEA SURFACE TEMPERATURES (29-30 C). GLOBAL AND ENSEMBLE MODELS ","ARE ON AGREEMENT WITH SWIFT DEVELOPMENT AND A STEADY SOUTHWESTWARD ","TRACK WITHIN THE NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ","ESTIMATED AT 23 TO 28 KNOTS.
