SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 08/24/16 0106Z
SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404
LATEST DATA USED: GOES-15 0030Z  RUMINSKI
.
LOCATION...HAWAII...
.
ATTN WFOS...HFO...
ATTN RFCS...AKRFC...
.
EVENT...HEAVY CONVECTIVE RAIN ON BIG ISLAND WITH POTENTIAL FOR HEAVY
RAIN MOVING INTO OAHU
.
SATELLITE ANALYSIS AND TRENDS...ON THE BIG ISLAND ANIMATED VIS IMAGERY
SHOWS AS SEA BREEZE AND EARLY SFC HEATING KICKED IN ON WEST SIDE OF
BIG ISLAND INVOF KAILUA KONA COLD TOPPED  CONVECTION (-65C) QUICKLY
DEVELOPED. ABBREVIATED PHTO SOUNDING SHOWS AMPLE MOISTURE (TPW CONTS
ABOVE 2")  WITH VERY LIGHT WINDS (MOSTLY BLO 10KT UP THRU 4H) WITH A
MOIST SKINNY CAPE PROFILE. CONVECTION WILL BE SLOW TO MOVE WITH EFFICIENT
RAIN RATES THAT COULD REACH/EXCEED 2"/HR. LATEST EXPERIMENTAL LIGHTNING
DENSITY PRODUCT SHOWS A SHARP INCR IN PAST HR OR SO IN TWO CLUSTER
ONE NR HONOKAA AND ANOTHER NEAR PAAUILO.
.
ANOTHER AREA OF CONVECTION IS SEEN S OF OAHU NEAR REMNANTS OF WEAK LOW
LEVEL CIRCULATION. SCATTEROMETER DATA SUGGESTS A WEAK CONVERGENT AXIS
EXTDG S OF OAHU WHICH IS ACTING AS FOCUS FOR CNVTN WHICH HAS BN PERSISTENT
FOR MUCH OF DAY. PHLI SOUNDING SHOWS SOMEWHAT STRONGER LOW/MID LEVEL
STEERING FLOW AS HIGH AS 20KT IN MOST OF CLOUD BEARING LAYER. LIGHTNING
DENSITY INDICATES STRIKES ARE REMAINING S OF 20N THUS FAR BUT RADAR AND
STLT IMAGERY SHOWING SHOWERS JUST OFF SW COAST OF OAHU. WITH EVER SO SLOW
APCH OF DEEPER TROF OUT NR 28N170W SHOWERS/CNVTN COULD BE DRAWN N OVER
OAHU. ALTHO CLDS WILL LIMIT DAYTIME HEATING COULD BE ENOUGH TO SUPPORT
INCREASED INSTABILITY FOR CNVTV DEVELOPMENT OVER THE ISLAND AS WELL.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION THREAT AREA
SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED BELOW IN APPROXIMATELY
10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 0100-0600Z...MEDIUM TO HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...OF IMMEDIATE CONCERN IS HEAVY RAIN ON W SIDE
OF BIG ISLAND WHERE HIGH RAIN RATES AND SLOW MVMNT COULD LEAD TO QUICK
3-4" TOTALS. IF CONVECTION GETS ANCHORED TO TERRAIN WITH WEAK ONSHORE
FLOW ISOLATED HIGHER AMNTS ARE PSBL. WILL CONT TO MONITOR DEVELOPMENT
OF CONDS FOR OAHU TO SEE IF CNVTN DRIFTS N. MAIN THREAT AREA WITH BE S
SIDE OF ISLAND.
