NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
0530 UTC TUE JAN 27 2015

BASED ON DATA THROUGH 0500 UTC JANUARY 27 2015

ANIMATION OF THE INFRARED SATELLITE IMAGERY OF THE PAST 12 HOURS
SHOWS THE DENSE LOW CLOUDS GRADUALLY CLEARING THE ISLANDS AS THE
DAY PROGRESSED. WINDWARD BIG ISLAND WAS THE ONLY AREA THAT REMAINED
INFLUENCED BY THE REMNANTS OF THE FRONT THAT PUSHED THROUGH THE STATE
OVER THE WEEKEND.

AT SUNSET...ALL OF OAHU MOLOKAI AND LANAI ARE MOSTLY FAIR. IT IS
STILL CLOUDY ON THE NORTHERN HALF OF KAUAI BUT DRY...WHILE THE REST
OF KAUAI AND NIIHAU ARE FAIR. THE HANA SIDE OF MAUI IS GETTING SOME
BROKEN LOW CLOUDS WHILE IT IS MOSTLY FAIR ELSEWHERE OF THE VALLEY
ISLE. THIS AREA OF CLOUDS OVER HANA EXTENDED OVER TO THE WINDWARD
SIDE OF THE BIG ISLAND...ALL THE WAY DOWN THE HAMAKUA COAST INTO THE
PUNA DISTRICT. ADDITIONAL PATCHES OF STABLE LOW CLOUDS ARE FLOWING
INTO THIS AREA FROM THE NORTHEAST AS WELL...MAINTAINING CLOUDY SKIES
BUT THERE ALL DAY. ON THE LEE SIDE OF THE BIG ISLAND...OVERCAST LOW
CLOUDS FORMED ALONG THE SLOPES AND ALSO THE ADJACENT WATERS FROM
KAILUA KONA TOWN SOUTHWARD. THE REST OF THE BIG ISLAND HAS FAIR
SKIES. EXCEPT FOR A COUPLE OF PLUME CLOUDS STRETCHING DOWNWIND FROM
OAHU/S WAIANAE COAST...AND FROM THE SOUTHERN MOST TIP OF MAUI...FAIR
SKIES RULED THE LEEWARD COASTAL WATERS. THE WINDWARD WATERS ARE
PRETTY MUCH CLOUDY WITH LARGE PATCHES OF SC MOVING MAINLY WESTWARD.
THESE PATCHES EXTENDED TO AS FAR NORTH AS 30N...WEST TO 165W...AND
TO 500 MILES NORTHEAST OF THE BIG ISLAND.

THE LOW CLOUDS PRESENT OVER THE ISLANDS ARE STABLE STRATOCUMULUS
/SC/ WITH TOPS OF 6 TO 7K FEET. THEY ARE MAINLY HIGH BASE...BETWEEN
35 HUNDRED AND 5K FEET. WHILE THE LOW LEVEL WINDS ARE STILL OUT OF
THE NORTHEAST ON THE BIG ISLAND...IT HAS SHIFTED ELSEWHERE OF THE
ISLAND CHAIN TO A EAST NORTHEAST DIRECTION...BLOWING AT A SPEED OF
20 TO 25 MPH. THIS CHANGE IN WIND DIRECTION HAS HELPED THIN OUT THE
CLOUDS.

ELSEWHERE ON SATELLITE...THE REMNANTS OF THE FRONT THAT MOVED
THROUGH THE STATE OVER THE WEEKEND IS STILL EVIDENT...WHERE A GOOD
PIECE OF IT STRETCHED FROM 20N142W TO 18N150W TO 16N158W TO 19N165W.
THE REMNANTS ARE SEEN AS A BAND ROUGHLY 200 MILES WIDE. THE BAND
WILL PASS SOUTH OF THE ISLANDS.

THE ISLANDS LATER THIS WEEK. IT HAS BEEN MOVING SOUTHEAST AT 15 MPH.
THE COORDINATES OF THE FRONT AT 7 PM HST ARE 30N165W 27N170W 23N180W.

49N154W AND WELL BEYOND THE DATELINE.
