ZCZC NFDSPENES ALL SPENES HIZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 03/18/20 0713Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES-17 0700Z;AMSU 0510Z;RADAR;OBS;MC . LOCATION...HAWAII... . ATTN WFOS...HFO... ATTN RFCS...APRFC... . EVENT...CONTINUED HEAVY RAIN . SATELLITE ANALYSIS AND TRENDS...A KONA LOW TO THE WEST OF THE HAWAIIAN ISLANDS CONTINUES TO BE SEEN IN GOES-WEST IMAGERY. THIS IS RESPONSIBLE FOR AN AXIS OF ENHANCED MOISTURE WHICH LIES BETWEEN OAHU AND MOLOKAI AND WHICH MAXES OUT AROUND 2.0 INCHES OF PW AS SEEN IN A RECENT AMSU PASS. THIS, COMBINED WITH CONVERGENT SOUTHERLY LOW-LEVEL FLOW BASED ON 00Z RAOBS, IS PRODUCING A LARGE AREA OF MODERATE TO HEAVY RAIN ACROSS THE CENTRAL AND EASTERN HAWAIIAN ISLANDS. THE LOW IS ALSO RESPONSIBLE FOR HIGHLY DIFFLUENT UPPER LEVEL FLOW PROVIDING AN EXCELLENT DYNAMIC ENVIRONMENT FOR THE EXISTING CONVECTION. IR TOPS HAVE BEEN COOLING OVER THE LAST FEW HOURS WITH CONVECTION APPROACHING THE ISLANDS. . SHORT TERM OUTLOOK VALID 0700-1300Z...HIGH CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...HEAVY RAIN CONTINUES TO FALL ACROSS THE CENTRAL AND EASTERN ISLANDS. RAIN RATES ESTIMATED BY RADAR OF UP TO 3 INCHES PER HOUR ARE OCCURRING, AND ARE LIKELY TO CONTINUE. UPSLOPE ENHANCEMENT FOR WINDWARD PORTIONS OF THE ISLANDS WILL RESULT IN HEAVY RAIN AND INCREASED RUNOFF, WHICH WILL MAKE FURTHER FLOODING ISSUES LIKELY. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
