ZCZC NFDSPENES ALL SPENES VIZ000-PRZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 03/03/20 0241Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: 200303/0210 GOES16 CH14 IR_11.2 . LOCATION...PUERTO RICO... . ATTN WFOS...SJU... ATTN RFCS... . EVENT...HEAVY RAINFALL POSSIBLE ACROSS NORTHERN PUERTO RICO . SATELLITE ANALYSIS AND TRENDS...THE LATEST RADAR TRENDS OBSERVED TRADE WIND SHOWERS PROGRESSING ACROSS NORTHERN PARTS OF THE ISLAND. THE LATEST UA RAOB SOUNDING DATA FROM TJSJ OBSERVED AN INCREASE IN SBCAPE GREATER THAN 600 J//KG BUT AN ABUNDANCE OF LOW LEVEL MOISTURE PRESENT WITH TPW AT 1.98" SUPPORTING LOW LEVEL MOISTURE CONVERGENCE ACROSS THE ISLAND. TRADE WINDS OBSERVED WERE FAIRLY LIGHT WITH 20KTS OR LESS OBSERVED ACROSS THE ISLAND WHICH IS SLOWING CELL MOTION ACROSS THE ISLAND. . AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED BELOW IN APPROXIMATELY 10-15 MINUTES. . SHORT TERM OUTLOOK VALID 0300-0900Z...LOW CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...RADAR TRENDS OBSERVED ISOLATED TO SCATTERED TRADE WIND SHOWERS PROGRESSING ACROSS THE ISLAND. HIGH TPW AND INCREASED INSTABILITY COULD LIKELY PROMOTE FURTHER DEVELOPMENT OF CONVECTIVE ACTIVITY PROGRESSING EAST TO WEST ACROSS THE ISLAND. HEAVY RAINFALL AND FLOOD RISK APPEARS LOW BUT IS POSSIBLE ESPECIALLY IN URBAN AREAS OF SAN JUAN AND NORTHERN PUERTO RICO WHERE SLOW MOVING CONVECTIVE ACTIVITY COULD OCCUR OVER THE FORECAST PERIOD. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
