ZCZC NFDSPENES ALL SPENES HIZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 11/10/18 1029Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES 15 1000Z;AMSU 0940Z;FCS . LOCATION...HAWAII... . ATTN WFOS...HFO... ATTN RFCS...AKRFC... . EVENT...HEAVY RAINFALL . SATELLITE ANALYSIS AND TRENDS...THE LATEST SATELLITE ANALYSIS REVEALS A BAND OF CLOUDS AND RAIN SHOWERS PROGRESSING SOUTH ACROSS THE NORTHERN ISLANDS OF HAWAII WITH HEAVY RAINFALL OCCURRING ON THE ISLAND OF OAHU PER LATEST SURFACE OBSERVATIONS AND RADAR. AMSU PRECIPITABLE WATER QUANTITIES EXCEEDS TWO INCHES ALONG THE FRONT AND HOURLY OBSERVATIONS OF 1.4 INCHES APPROXIMATELY FOR RAINFALL TOTALS INDICATE A POTENTIAL FOR FLASH FLOODING WHICH HAS ALREADY BEEN REPORTED ON OAHU. EXPECT THE TREND TO CONTINUE AS THE FRONT MOVES TO THE SOUTH WITH EMBEDDED POCKETS OF HEAVIER RAINFALL WITH TERRAIN INDUCED ENHANCEMENT RESULTING IN BETTER RAINFALL RATES. SATELLITE IMAGERY DOES INDICATE COOLER CLOUD TOPS UPSTREAM THAT WILL TRAVEL ALONG THE FRONT FROM WSW-NNE TOWARDS OAHU AND MOLOKAI AND ISLANDS IN THE MIDDLE OF THE HAWAIIAN ISLAND CHAIN; THEREFORE, THE FLASH FLOOD RISK IS APPRECIABLE AS HEAVY RAINFALL ACCOMPANIES THE PASSING OF THIS COLD FRONT. . SHORT TERM OUTLOOK VALID 1030-1430Z...MEDIUM CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...MODERATE TO HEAVY RAINFALL WILL ACCOMPANY THE PASSAGE OF A COLD FRONT. EMBEDDED HEAVIER RAINFALL RATES WILL POTENTIALLY GENERATE FLASH FLOODING WITH BETTER RAINFALL RATES AS THE FRONT MOVES TO THE MIDDLE PORTION OF THE HAWAIIAN ISLANDS. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
