HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
0030 UTC FRI FEB 12 2016

BASED ON DATA THROUGH 0000 UTC FEBRUARY 12 2016

SATELLITE IMAGERY CENTERED OVER THE MAIN HAWAIIAN ISLANDS SHOWS
YET ANOTHER SPECTACULARLY SUNNY DAY OVER MOST ISLAND AREAS. SKIES
ARE NEARLY COMPLETELY SUNNY OVER THE ISLANDS FROM OAHU TO THE BIG
ISLAND...WITH SCATTERED TO BROKEN LOW CLOUDS NOTED OVER THE ISLAND
OF KAUAI.

SOME EXCEPTIONS TO THE COMPLETELY SUNNY SKIES INCLUDE THE
SOUTHERN PORTION OF THE KOOLAU SLOPES...AND OVER PORTIONS OF THE
WAIANAE SLOPES ON OAHU WHERE SCATTERED LOW CLOUDS ARE SEEN. A
NARROW PLUME OF LOW CLOUDS IS OVER THE SOUTHWEST SIDE OF
MOLOKAI... EXTENDING JUST WEST OF THE ISLAND OVER NEAR SHORE
WATERS NEAR LAAU POINT. ALSO SCATTERED LOW CLOUDS ARE NOTED OVER
THE EXTREME EASTERN TIP OF MOLOKAI NEAR CAPE HALAWA. ON
LANAI...SCATTERED LOW CLOUDS ARE BETWEEN THE AIRPORT AND
KAUMALAPAU HARBOR...WHILE THE ONLY INTERRUPTION TO THE CLEAR SKIES
ON MAUI IS A SMALL AREA OF SCATTERED TO BROKEN LOW CLOUDS OVER THE
LOWER SOUTHWEST SLOPES OF HALEAKALA...MAINLY BETWEEN KEOKEA AND
ULUPALAKUA. ON THE BIG ISLAND...A SMALL PATCH OF LOW CLOUDS IS
LOCATED JUST SOUTHWEST OF THE MAUNA KEA SUMMIT...WITH BROKEN TO
OVERCAST STABLE LOW CLOUDS ALONG THE LOWER LEEWARD SLOPES FROM
NEAR KEAHOLE POINT TO HONAUNAU...AND ALONG THE SOUTHEAST FLANK OF
MAUNA LOA UPSLOPE FROM WOOD VALLEY AND PAHALA. ON KAUAI THE
SCATTERED TO BROKEN LOW CLOUDS ARE ISLAND-WIDE...WITH A NARROW
PLUME OF STABLE LOW CLOUDS EXTENDING FROM LEEWARD KAUAI OVER
NIIHAU...WITH AN AREA OF BROKEN TO OVERCAST LOCATED OVER NEAR
SHORE WATERS JUST WEST OF NIIHAU.

A LIGHT TO MODERATE TRADE WIND FLOW PREVAILS THIS AFTERNOON...AND
LOW CLOUD COVER OVER NEAR SHORE WATERS HAS DIMINISHED SINCE THIS
MORNING...WITH FEW TO SCATTERED STABLE LOW CLOUDS NOTED. LOW
CLOUDS NEAR THE ISLANDS ARE MOVING TOWARD THE WEST AT SPEEDS
BETWEEN 10 AND 15 MPH. LONGER SATELLITE LOOPS INDICATE THAT THE
LOW-LEVEL FLOW HAS VEERED FROM NORTHEAST TO EAST OVER THE PAST 12
TO 15 HOURS.

THE TROPICAL CENTRAL NORTH PACIFIC /TCNP/ FROM 10N TO 30N BETWEEN
140W AND THE DATE LINE IS DOMINATED BY STABLE LOW CLOUDS WITH
EMBEDDED SHOWERY ELEMENTS...AND THE COVERAGE OF THESE CLOUDS HAS
DIMINISHED DURING THE COURSE OF THE DAY. NORTHEAST TO SOUTHWEST
ORIENTED CLOUD BANDS ARE LOCATED IN THE FAR NORTHEAST AND
NORTHWEST CORNERS OF THE AREA...WITH A 200 MILE WIDE BAND OF
BROKEN TO OVERCAST LOW AND MIDDLE CLOUDS TRACKING EASTWARD NEAR
MIDWAY ATOLL. IN THE NORTHEAST CORNER...IT APPEARS THAT MOISTURE
ASSOCIATED WITH A DISSIPATED FRONT HAS BECOME NEARLY STATIONARY
WITHIN 175 MILES OF A LINE FROM 27N 140W TO 23N 149W. ISOLATED
THUNDERSTORMS THAT WERE IN THIS AREA THIS MORNING HAVE SHIFTED
EAST OF 140W.

WATER VAPOR IMAGERY SHOWS A PERSISTENT RIDGE ALOFT CENTERED FAR
SOUTHWEST OF THE ISLANDS...WITH AN ASSOCIATED RIDGE EXTENDING
EASTWARD ALONG 10N AND 12N. A DRY AND STABLE NORTHWEST FLOW ALOFT
PREVAILS OVER THE HAWAIIAN ISLANDS.
