SATELLITE ANALYSIS AND TRENDS...G12 IR AND VIS IMAGERY HAS BEEN SHOWING
BAND OF WARM TOP CNVTN EXTENDING FM APPX 30 MI W OF PUERTO RICO THRU
CENTRAL/N CENTRAL PARTS OF THE ISLAND. SINCE 1615Z..CLOUD TOPS HAVE BEEN
STEADILY COOLING AND EXPANDING FM THE WRN COAST TO N CENTRAL ZONE. MAIN
CONTRIBUTING FACTORS APPEAR TO BE SFC CONVERGENCE PER MCIDAS OBJECTIVE
ANALYSIS..AND..APPARENT SW-NE SHORT WAVE ACRS ERN HISPANOLA WITH EMBEDDED
VORT CENTER..PER GOES IR AND VIS IMAGERY ANIMATIONS.
.
MICROWAVE PW IMAGERY SHOWS W-E PW PLUME EXTENDING FM YUCATAN PENINSULA EWD
ACRS PUERTO RICO TO 60W. PW VALUES OVER PR ARE CLOSE TO 2". THE CONCERN
IS THAT WITH THE COMBINATION OF SFC CONVERGENCE ALONG WITH INFLUENCE
OF SHORT WAVE TO THE W..CNVTN WILL CONTINUE TO INCR OVER THE NEXT FEW
HRS. WITH THE HIGH PW'S THROWN INTO THE MIX..WOULD EXPECT HVY RATES
AND TOTALS DURING THE AFTN. STLT TRENDS ALSO SUGGEST LIKELIHOOD OF CELL
MERGERS. THUS..WOULD NOT BE SURPRISED TO SEE SOME RAINFALL TOTALS OF 3"
OR MORE OVER SOME LOCATIONS.
