EVENT...WARM TOP CNVTN INCRG NR MOST ISLANDS...UPPR LOW STRENGTHENING
.
SATELLITE ANALYSIS AND TRENDS...LATEST GOES AND MICROWAVE IMAGERY TRENDS
PORTEND HVY SHOWERS/TSTMS FOR MANY OF THE HAWAIIAN ISLANDS. FIRST..WV
IMAGERY SHOWS UPPR LOW SITTING NR 25N 160W WITH CURVATURE/ CIRCULATION
AROUND THE LOW INCRG. UPPR TROF WELL TO THE SSW OF THE BIG ISLAND..WITH
LTL MOVEMENT NOTED OF THE BASE OF THE TROF. BOTH ARE DUE UPSTREAM
JET DIGGING W OF THE UPPR LOW/TROF. IN TERMS OF CNVTN..THE ONLY AREA
THAT HAS ANY EWD SHIFT IS THE CELLS NR AND E OF KAUAI. OTHER WISE..THE
BANDS OF SHOWERS/TSTMS OVER  MOLOKAI THRU MAUI AREA..E BIG ISLAND AND
OFFSHORE..SHOW LTLT MOVEMENT. INDIVIDUAL CELLS ARE MOVG NE..BUT THE
OVERALL BANDS HAVE BEEN FAIRLY STNRY. THIS IS DUE TO SWRLY FLOW PER GOES
STLT WINDS.
.
NOAA AMSU IMAGERY SHOWS PW'S IN THE 1.5-1.7" RANGE AROUND THE REGION. HUGE
COMMA HEAD OF HIGH PW'S HAS BEEN STNRY WITH SRN PORTION EXPANDING ACTR
KAUAI TO MOLOKAI. COMMA TAIL EXTENDS ACRS/E OF THE BIG ISLAND. THE TAIL
HAS SHIFTED A BIT EWD..WITH NARROW CORRIDOR OF SOMEWHAT LOWER PW'S TRYING
TO DRIFT IN BEHIND IT. THIS MAY RESULT IN ANY HVY SHOWERS/TSTMS FAVORING
ERN/SERN PORTIONS OF THE BIG ISLAND. BUT WITH LL SWRLY FLOW..CANNOT RULE
OUT SOME SHOWERS ALONG W COAST AS WELL. AS FOR RAIN RATES..AMSU AND
TRMM RATES WERE IN THE 0.5-0.8"/HR RANGE JUST OFF THE E COAST OF THE
BIG ISLAND. TRMM RATES NR MAUI AND NR KAUAI WERE IN THE 0.4-0.5"/HR
RANGE. MICROWAVE RAIN RATES ARE AREAL AVERAGES..SO THEY ARE NOT
NECESSARILY INDICATIVE OF THE HIGHEST RATES.
.
BOTTOM LINE IS THAT WHILE ALL THE HAWAIIAN ISLANDS FACE THE THREAT OF
SOME MOD/HVY SHOWERS AND TSTMS DURING THE COURSE OF THE MORNING/DAY..OF
IMMEDIATE CONCERN IN THE SHORT TERM IS THE AREA FM OAHU TO MAUI AS WELL
AS ERN BIG ISLAND. OF PARTICULAR CONCERN IS THE POSSIBILITY FOR SOME CELL
TRAINING INVOF MAUI/KAHOOLAWE AND ERN BIG ISLAND AND FOR OAHU AS WELL.
