.
SATELLITE ANALYSIS AND TRENDS...HVY SHOWERS WHICH AFFECTED BIG ISLAND
EARLIER HAVE DRIFTED N OF ISLAND. MEANWHILE..OVERALL FOCUS HAS NOW SHIFTED
TO THE AREA FM MAUI TO OAHU. LARGE AREA OF WARM TOP SHOWERS  SE/E OF MAUI
HAS BEEN STEADILY INCRG IN COVERAGE..WITH WRN EXTENT OF SHOWERS AFFECTING
THE ABOVE-MENTIONED ISLANDS..ESP MAUI AND MOLOKAI. G11 WV IMAGERY SHOWS
THAT UPPR LOW IS CENTERED W OF THE BIG ISLAND. HOWEVER..OVERALL CIRC/FLOW
AROUND IT HAS BECOME MORE ELONGATED WITH TIME..MORE W-E. THIS ELONGATION
HAS LED TO FOCUS OF SHOWERS SHIFTING FM BIG ISLAND..TO FURTHER N...WITH
EASTERLY COMPONENT FLOW SHUNTING SHOWERS TOWARD/ACRS THE AREA ENCOMPASSING
MAUI OAHU. SOME SHOWERS STILL LINGER OFF OF NE COAST OF BIG ISLAND..BUT
FOR NOW..LOOKS LIKE AT LEAST A RESPITE FOR BIG ISLAND. ONE THING TO
WATCH IS THE SW-NE BAND OF INCRG SHOWERS SE OF THE BIG ISLAND. THERE IS
SOME DRIFT TWD THE N AND NW..AND IT IS PSBL THAT IT COULD AFFECT THE
BIG ISLAND LATER TODAY. GOES 11 DPI IMAGERY SHOWS THAT CORE OF CURVED
PW PLUME HAS SHIFTED N OF THE BIG ISLAND..WITH 1"PLUS PW'S SURGING WWD
ACRS THE AREA BETWEEN SRN MAUI AND KAUAI. BUT DPI ALSO SHOWS SECOND PLUME
OF HIGH PW'S WITH CNVTN TO THE S. THUS..IF THIS BAND DOES MAKE IT UP TO
THE BIG ISLAND..ANOTHER ROUND OF HVY SHOWERS WILL OCCUR THERE.
.
IN THE SHORTER TERM..STLT IMAGERY INDICATES MOD/HVY SHOWERS WILL BE
FOCUSED OVER MAUI/MOLOKAI AREA THIS MORNING/AFTN AT TIMES..AS FAR N AS
OAHU. SOME SHOWERS WILL ALSO AFFECT KAUAI..BUT THEY ARE MORE SCT AND
EVEN WARMER TOPPED. AS FOR RAINFALL ESTIMATES..VERY WARM TOP NATURE OF
CNVTN IS PRECLUDING CONFIDENT DETERMINATION GOES ESTIMATES ATTM. EARLIER
NASA TRMM ESTIMATES FROM 0757Z INVOF THE BIG ISLAND HAD PIXELS IN THE
0.3"/HR TO 0.6"/HR RANGE..KEEPING IN MIND THAT MICROWAVE RAIN RATES ARE
AREAL AVERAGES AND CAN UNDERESTIMATE THE HEAVIEST RATES.  THOSE ARE THE
SAME SHOWERS THAT HAVE NOW MOVED N INVOF MAUI.
