SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 12/09/16 2016Z
SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404
LATEST DATA USED: GOES WEST 1930Z PL
.
LOCATION...HAWAII...
.
ATTN WFOS...HFO...
ATTN RFCS...APRFC...
.
EVENT...HEAVY RAINFALL THREAT OVER THE CENTRAL AND SRN HAWAIIAN ISLANDS
MAINLY MOLOKA`I AND SOUTH
.
SATELLITE ANALYSIS AND TRENDS...WATER VAPOR IMAGERY CONTINUES TO  INDICATE
A LARGE PLUME OF SUBTROPICAL MOISTURE EXTENDING ACROSS THE ISLANDS WITH
A SHARP CUT-OFF NEAR AND TO THE W OF KAUAI--ALSO PERHAPS A SUBTLE S/W
FEATURE NOTED UPSTREAM SW OF THE ISLANDS WHILE A STRONGER S/W WAS N OF
THE AREA. SATELLITE DERIVED WINDS PLACE THE ISLANDS WITHIN THE DIVERGENT
RIGHT ENTRANCE REGION OF A MODEST UL JET.  1910Z AMSU PW PASS INDICATES
BETWEEN 1.5-2.0" WHILE LIGHTNING DENSITY INDICATES LITTLE IN THE WAY OF
DEEPER CONVECTION WITHIN THE FORECAST AREA. MEANWHILE VISIBLE IMAGERY
SHOWING BREAKS IN THE OVERCAST FROM MAUI AND WESTWARD WITH WARMING OF
CLOUD TOPS EVIDENT IN IR ANIMATION OVER THE PAST FEW HOURS. LOW LEVEL
WINDS AS PER THE 1140Z SCATTEROMETER PASS SHOWS RATHER MEAGER SE WINDS.
.
SHORT TERM OUTLOOK VALID 2000-0200Z...LOW CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...BELIEVE THAT ALTHOUGH A HEAVY PRECIPITATION
RISK EXISTS THE LACK OF DISCRETE FOCI--IE STRONG S/W TROUGH AND/OR
LL CONVERGENCE--WITHIN AN OTHERWISE FAVORABLE MOIST ENVIRONMENT
PRECLUDES A HIGHER CONFIDENCE FOR WIDESPREAD CONVECTIVE DEVELOPMENT.
HOWEVER...PRECIPITATION MEAN MOVEMENT ORTHOGONAL TO TERRAIN WILL ENHANCE
LOCAL RISKS.
