ZCZC NFDSPENES ALL SPENES PRZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 09/07/19 1630Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES-16 16Z CH02,CH13,GLM;TJSJ OBS;MC . LOCATION...PUERTO RICO... . ATTN WFOS...SJU... ATTN RFCS... . EVENT...HEAVY RAIN . SATELLITE ANALYSIS AND TRENDS...GOES-16 VIS IMAGERY AND LIGHTNING DATA AT 16Z SHOWS RAPIDLY-DEVELOPING CONVECTION OVER EASTERN PUERTO RICO. SIGNIFICANT DEEP MOISTURE WAS NOTED FROM THE 12Z TJSJ RAOB, WITH PW OF 2.18 INCHES AND T-TD LESS THAN 5C FROM THE SFC TO 700MB. THIS IS CONTRIBUTING TO SIGNIFICANT INSTABILITY, WITH CAPE OF CLOSE TO 3000 J/KG IN THE SOUNDING THAT IS LIKELY GREATER NOW WITH DAYTIME HEATING. A TROPICAL WAVE TO THE WEST AND A SFC TROF TO THE EAST ARE PROVIDING DYNAMIC LIFT FOR THE CONVECTION. IR CLOUD TOPS OF -61C AT PRESENT CORRELATE TO AT LEAST 40000 FEET. . SHORT TERM OUTLOOK VALID 1630-0000Z...HIGH CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...THE MOIST, UNSTABLE ATMOSPHERE ACROSS PUERTO RICO WILL REMAIN CONDUCIVE TO DEEP CONVECTION THROUGH SUNSET. PARTS OF THE ISLAND SAW HEAVY RAIN YESTERDAY, WITH TJSJ RECEIVING 2.82 INCHES OF RAINFALL. THUS, SOILS MAY STILL BE QUITE SATURATED AS MORE HEAVY RAINFALL OCCURS TODAY. THIS WILL ALLOW FOR THE POTENTIAL FOR FLOODING ISSUES, ESPECIALLY AROUND HIGHER TERRAIN. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
