EVENT...HVY CNVTN FM SE PR TO SAN JUAN AND VCNTY..VERY COLD TOPS OVER SE
.
SATELLITE ANALYSIS AND TRENDS...SINCE 0011Z SPENES..CONVECTIVE CLOUD
TOPS HAVE COOLED SIGNIFICANTLY OVER THE EVENT AREA. MOST NOTICEABLE
IN THE PAST HR ARE THE RAPIDLY COOLING TOPS ALONG THE SE COAST..WHERE
CLOUD TOPS HAVE COOLED FM -44C TO -61C. THESE SHOWERS/TSTMS ARE MOVG
NW..WITH NRN EDGE ALREADY SPREADING INTO THE ERN INTERIOR AND POISED TO
SPREAD INTO THE CENTRAL INTERIOR. DUE TO THE TEMP AND RAPID COOLING OF
THE CLOUD TOPS ALONG WITH PW'S OF 2.3" OR MORE..MANUAL STLT EST SUGGEST
RAINFALL RATES OF BTWN 1.5-2"/HR.  THE CELLS ARE MOVG..WHICH WOULD CUT
DOWN ON TOTALS. HOWEVER..DESPITE MOVEMENT..TERRAIN EFFECT SHOULD PLAY
A SIGNIFICANT ROLE IN ENHANCING RAINBURST. ANOTHER CONCERN IS FOR CELL
TRAINING ACRS THE AREA FM SE PR THRU CENTRAL INTERIOR SECTIONS..ESP SINCE
SHOWERS AND TSTMS EXTEND OFFSHORE.  BASED ON THESE TRENDS/FACTORS ..TOTALS
OF 2-3" FM CURRENT THIS ACTIVITY IS LIKELY OVER SOME LOCATIONS..AND
PERHAPS 3"PLUS.
