SATELLITE ANALYSIS AND TRENDS...WARM TOP CELLS HAVE BEEN NEARLY STNRY
OVER THE WRN END OF PR FOR THE PAST FEW HRS. VIS IMAGERY SHOWS THAT MOST
OF THE CELLS PREVIOUSLY OVER THE CENTER OF THE ISLAND HAVE MOVED OUTWARD
ALONG THE SRN AND WRN EDGES. SOME OF IT HAS STARTED TO DIE OFF ALONG THE
SRN EDGE BUT NEW OVERSHOOTING TOPS WERE JUST NOTICED IN 2025Z IMAGERY OVER
SALINAS AND PATILLAS MUNICIPALITIES. ANOTHER LARGER OVERSHOOTING TOP WAS
SEEN OVER THE FAR WRN END OF THE ISLAND INVOF MAYAGUEZ MUNICIPALITY. ALL
THESE CELLS ARE VERY WARM TOPPED WITH ONLY THE ONE OVER MAYAGUEZ
SHOWING ANY IR ENHANCEMENT AT -20C. MOST OF THE SURROUNDING WARM TOP
CELLS OVER THE WRN END OF THE ISLAND HAVE STAYED RELATIVELY STNRY AND
APPEAR AS THOUGH THEY SHOULD REMAIN SO UNTIL WEAKENING OCCURS WITH LOSS
OF DIURNAL HEATING. MANUEL STLT ESTIMATES GIVE BETWEEN 1.5-2" OVER PARTS
OF THE NWRN END OF THE ISLAND IN THE LAST HR. HAVE ALSO NOTICED THOUGH
THAT NEW SEABREEZE CU HAVE FORMED ALONG THE ENTIRE N SIDE OF THE ISLAND
WHICH HAS BEEN STRENGTHENING AND SHOULD MOVE FURTHER INLAND OVER THE NEXT
1-2 HRS WITH SFC WINDS FROM THE N/NE. ISLAND IS STILL WITHIN 1.7-1.9"
TONGUE OF PW MOISTURE PER 1804Z AMSU PASS THAT STRETCHES EWD FROM 2"
MAX AROUND HISPANOLA WHERE S/WV IS SEEN ON WV IMAGERY SE TO NW.
