ZCZC NFDSPENES ALL SPENES PRZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 02/25/20 0830Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES 16 WV 0750Z; AMSU 0110Z; RADAR 0808Z; FCS . LOCATION...PUERTO RICO... . ATTN WFOS...SJU... ATTN RFCS... . EVENT...HEAVY RAINFALL POTENTIAL . SATELLITE ANALYSIS AND TRENDS...GOES 16 SATELLITE IMAGERY SHOWS CLOUDS AND MOISTURE TRAVELING IN FROM THE EAST-SOUTH-EAST MOVING OVER THE ISLAND OF PUERTO RICO. AMSU 89GHz IMAGERY INDICATES HIGHER MOISTURE ALONG THE FRONT WITH GPS PW QUANTITIES 0F 1.5 TO 1.9 INCHES. THE 00Z RAOB SOUNDING INDICATED OVER 2.0 INCHES OF PRECIPITABLE WATER AND A 4 KM DEEP COLUMN WITH DEW POINT DEPRESSIONS OF ZERO THROUGHOUT THE 4 KM DEPTH, AND CAPE WAS 473 J/KG. AT THE MID LEVELS OF THE ATMOSPHERE THE WIND VECTOR FLOW IS DIVERGENT AT 500 MB. ALL THINGS CONSIDERED, PERSISTENT LIGHT TO MODERATE RAINFALL MAY ACCUMULATE ENOUGH TO GENERATE PONDING OF WATER IN MODERATE SHOWERS AND A POTENTIAL FOR SMALL STREAM AND SOME URBAN FLASH FLOODING SHOULD THE RAIN PERSIST. . SHORT TERM OUTLOOK VALID 0830-1430Z...LOWER CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...LOCAL TJSJ RADAR INDICATED RAIN SHOWERS OCCURRING OVER PUERTO RICO WITH RADAR ESTIMATED ONE HOUR TOTALS AS OF 09Z UNDER A QUARTER OF AN INCH, HOWEVER, MORE CLOUDS ARE STREAMING IN FROM THE EAST-SOUTH-EAST WITH MORE RAIN SHOWERS TO THE EAST OF PUERTO RICO MOVING TOWARDS AND OVER THE ISLAND. THE NORTHEAST CORNER OF PUERTO RICO SEEMS TO BE THE MOST SUSCEPTIBLE PART OF THE ISLAND TO RECEIVE THE BEST RAINFALL IN THE NEAR TERM. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
