ZCZC NFDSPENES ALL SPENES HIZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 01/11/18 1051Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: AMSU 0030Z; GOES HIGH DENSITY WINDS; . LOCATION...HAWAII... . ATTN WFOS...HFO... ATTN RFCS...AKRFC... . EVENT...POTENTIAL HEAVY RAINFALL . SATELLITE ANALYSIS AND TRENDS...THE LATEST SATELLITE IMAGERY AND HIGH DENSITY WIND ANALYSIS INDICATES THE PRESENCE OF SEVERAL FEATURES THAT MAY COMBINE FOR A HEAVY RAIN EVENT OVER THE SOUTHERN PORTION OF THE HAWAIIAN ISLAND CHAIN. SURFACE MOISTURE CONVERGENCE CENTERED OVER THE ISLANDS AND AN AREA OF DIVERGENCE ALOFT GENERATED BY THE LEFT EXIT REGION OF A JET STREAK PRESENTLY POSITIONED SOUTH OF THE HAWAIIAN ISLANDS IS SET TO POSITIVELY INFLUENCE UPWARD VERTICAL VELOCITIES OVER HAWAII AND POTENTIALLY PRODUCE HEAVY RAINFALL. SATELLITE DERIVED PRECIPITABLE WATER RANGES FROM 1.2 TO 1.6 INCHES, ALTHOUGH SATELLITE IMAGERY IS NOT IMPRESSIVE IN TERMS OF LOOKS. HOWEVER, FLASH FLOODING CAN NOT BE RULED OUT BASED UPON THE PRESENCE OF THE VARIOUS METEOROLOGICAL PARAMETERS IN PLACE OVER HAWAII. . SHORT TERM OUTLOOK VALID 1045-1800Z...LOW CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...SHOWERS OVER THE BIG ISLAND OF HAWAII MAY BE OCCASIONALLY AND BRIEFLY MODERATE TO HEAVY WITH SOME MINOR FLOODING POTENTIAL. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
