ZCZC NFDSPENES ALL SPENES HIZ000- . SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 08/24/18 0612Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES-15 EIR-WV 0530Z / MIMIC-TPW2 04Z / AMSU-PWAT 0510Z / AMSU-RAIN 05Z; BAK . LOCATION...HAWAII... . ATTN WFOS...HFO... ATTN RFCS...APRFC... . EVENT...HURRICANE LANE HEAVY RAINFALL . SATELLITE ANALYSIS AND TRENDS...LATEST GOES-15 EIR AND RADAR LOOPS SHOW AN APPARENT SUBSIDENCE ZONE DEVELOPING N OF THE CDO OF LANE. CLOUD TOPS HAVE WARMED IN THE PAST 2 HRS WITH A DECREASE IN PCPN COVERAGE AND INTENSITY OVER THE MOST OF STATE. THE EXCEPTION IS THE NORTHERN AND EASTERN PART OF THE BIG ISLAND WHERE STRONG ESE FLOW AND OROGRAPHIC LIFT CONTINUE HEAVY RAINS WITH A 6 HR TOTAL OF 4.45" AT HONOKAA. AS WITH YESTERDAY, TRANSIENT COLDER CLOUD FLARE-UP CELLS ARE OCCURRING ALONG THE N COAST, ENHANCING RAINFALL AMOUNTS. 00Z PHTO RAOB ONCE AGAIN HAS A NEAR RECORD PWAT VALUE (2.48") AND EARLIER GFS ANALYSIS INDICATED A LARGE AREA OF PWAT ANOMALIES 5 STANDARD DEVIATIONS ABOVE AVERAGE OVER THE EASTERN ISLANDS EXTENDING OFFSHORE TO THE E FOR A FEW HUNDRED MILES. . SHORT TERM OUTLOOK VALID 0615-1215Z...MEDIUM-HIGH CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...WITH LANE'S CENTER ONLY SLOWLY MOVING N, LITTLE CHANGE IN THE OVERALL FLOW IS EXPECTED IN THE SHORT TERM. THE MIMIC-TPW2 PRODUCT SHOWS AN ESTABLISHED AXIS OF VERY HIGH PWAT VALUES FEEDING DIRECTLY INTO THE BIG ISLAND FROM THE ESE, SO ANOTHER 2-5" OF RAIN IS LIKELY ON NORTH AND EAST FACING SLOPES. THE AMSU-RAIN PRODUCT INDICATES INCREASING AREAL COVERAGE OF .50-1.00" HOURLY RAINFALL RATES OFFSHORE TO THE E WHICH MAY START TO IMPACT THE AREA LATER IN THE OUTLOOK PERIOD. . ....NESDIS IS A MEMBER OF NWSCHAT (NESDISSATELLITEPRECIP).... ....NESDIS IS A MEMBER OF 12 PLANET.... .
