HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
1230 UTC MON NOV 24 2014

BASED ON DATA THROUGH 1200 UTC NOVEMBER 24 2014

WATER VAPOR IMAGES SHOWED A TROUGH OF LOW PRESSURE IN THE MIDDLE
ATMOSPHERE DEEPENING TOWARD THE MAIN HAWAIIAN ISLANDS FROM THE
NORTHWEST. A CLOUD BAND ASSOCIATED WITH A FRONT SUPPORTED BY THE
TROUGH WAS LOCATED WITHIN 200 MILES OF THE LINE FROM 30N 156W TO 26N
157W AND FURTHER NORTH...AND WITHIN 75 MILES OF THE CURVE FROM 26N
157W TO 19N 167W TO 19N 180 AND FURTHER WEST. THIS FEATURE CONSISTED
MOSTLY OF DEEP CLOUD LAYERS WITH EMBEDDED THUNDERSTORMS NORTH OF
ABOUT 26N 157W...AND MIDDLE TO LOW CLOUD LAYERS FROM 26N 157W TO 19N
168W...BUT FRAGMENTING LOW TO MIDDLE CLOUD LAYERS WEST OF 19N 168W.
THIS FEATURE MOVED SOUTHEAST AT 10 TO 15 MILES AN HOUR. MODERATELY
TO DENSELY PACKED COLD-AIR CUMULI PREVAILED NORTHWEST OF THE BAND.
BANDS OF CUMULI...STRATOCUMULI...AND AND TOWERING CUMULI FORMED
PARALLEL TO THE MAIN CLOUD BAND WITHIN ABOUT 350 MILES TO THE SOUTH
OF IT.

TO THE NORTHEAST...WATER VAPOR IMAGES SHOWED A SHALLOWER TROUGH OF
LOW PRESSURE IN THE MIDDLE ATMOSPHERE LOCATED NEAR 27N 143W. THIN
HIGH CLOUD LAYERS ASSOCIATED WITH THIS TROUGH PARTLY OBSCURED LOWER
FEATURES WITHIN 100 MILES OF THE LINE FROM 30N 145W TO 24N 143W AND
FURTHER NORTH.

TO THE SOUTH...LIGHT THUNDERSTORM ACTIVITY CONTINUED IN THE ITCZ
FROM 09N TO 03N...ALMOST ENTIRELY WEST OF 168W. LAYERED HIGH TO
MIDDLE DEBRIS CLOUDS FROM THIS AND EARLIER CONVECTION OBSCURED LOWER
FEATURES PARTLY TO MOSTLY FROM 13N TO 03N ACROSS MOST OF THE AREA...
AND AS FAR NORTH AS 22N EAST OF 151W.

OTHERWISE...CLOUD COVER ACROSS HAWAIIAN WATERS CONSISTED MAINLY OF
LOOSE CLUMPS AND STREAMS OF MARINE STRATOCUMULI AND CUMULI MERGING
INTO AREAS OF NEARLY SOLID OVERCAST EAST OF 152W. THESE STREAMS
CURVED FROM SOUTHEAST TOWARD THE NORTHWEST AND THEN THE NORTH.
INDIVIDUAL SMALL CUMULI ALSO WERE PRESENT THROUGHOUT. WEST OF
160W...THESE CLOUDS GENERALLY MOVED TOWARD THE WEST SOUTHWEST AT 15
TO 20 MILES AN HOUR. THESE CLOUDS TYPICALLY ROSE TO HEIGHTS OF 7000
TO 10000 FEET.

ACROSS THE MAIN HAWAIIAN ISLANDS...CLOUD COVER CONSISTED MOSTLY OF
MARINE STRATUS LAYERS AND STRATOCUMULI OVER MAUI COUNTY...AND THE
MAIN FRONTAL CLOUD BAND MOVING SOUTHEAST OVER KAUAI COUNTY. LAYERED
DEBRIS CLOUDS FROM AFTERNOON CUMULUS BUILDUPS ON SUNDAY LARGELY HAD
DISSIPATED. THESE CLOUDS GENERALLY ROSE TO HEIGHTS OF 7000 TO 10000
FEET...THOUGH THE LAYERS OF THE CLOUD BAND APPROACHED 15000 FEET.
RADAR DATA FROM NEAR THE ISLANDS SHOWED AREAS OF RAIN OVER AND
SOUTHWEST OF THE ALENUIHAHA CHANNEL...OVER AND SOUTHWEST OF KAUAI
COUNTY...AND OFFSHORE WELL TO THE NORTHEAST OF MAUI. ELSEWHERE...
RADAR DATA SHOWED ISOLATED SHOWERS AT MOST.

A LARGE...DEEP UPPER LEVEL TROUGH EXTENDED SOUTH FROM THE ALEUTIAN
ISLANDS DOWN TO JUST WEST OF KAUAI.  THE TROUGH AXIS PASSED THROUGH
40N 165W TO 30N 167W TO 23N 169W.  THE TROUGH WAS MOVING EAST NEAR
25 MILES AN HOUR.

A SURFACE FRONT WAS LYING BENEATH THE EAST EDGE OF THE UPPER TROUGH.
THE FRONT EXTENDED THROUGH 30N 159W TO 23N 165W TO 20N 172W TO 19N
178W.  IT WAS ABOUT 270 MILES NORTHWEST OF KAUAI EARLY THIS SUNDAY
AFTERNOON AND HAD ACCELERATED SOUTHEAST TOWARD THE ISLANDS NEAR 20
MILES AN HOUR.

THE ASSOCIATED FRONTAL CLOUD BAND WAS ABOUT 125 MILES WIDE SOUTH OF
26N AND WAS COMPRISED OF BROKEN TO OVERCAST LOW CLOUDS.  NORTH OF
26N...THE CLOUD BAND WIDENED TO MORE THAN DOUBLE IN WIDTH AND
CONSISTED OF OVERCAST CLOUD LAYERS WITH TOPS TO JUST OVER 35000
FEET.

AHEAD OF THE FRONT...NEAR THE HAWAIIAN ISLANDS...ONE LARGE CLUSTER OF
MOSTLY OVERCAST LOW CLOUDS SAT JUST SOUTH OF OAHU.  THIS CLOUD
CLUSTER WAS UP TO 100 MILES WIDE AND STRETCHED NEARLY 225 MILES TO
THE SOUTHWEST OF OAHU.  IT WAS STATIONARY.

OTHER PATCHES AND SMALL CLOUD CLUSTERS WERE NOTED MAINLY EAST OF THE
BIG ISLAND AND MAUI.  THESE LOW CLOUDS WERE FLOWING NORTHWEST AT 20
MILES AN HOUR.  LOW CLOUDS SEEN WEST OF KAUAI WERE HEADED TOWARD
THE EAST AT JUST UNDER 10 MILES AN HOUR.  DIRECTLY OVER THE
ISLANDS...SKIES WERE MOSTLY SUNNY WITH A FEW PARTLY CLOUDY AREAS.
HOWEVER...THERE WERE SOME MOSTLY CLOUDY CONDITIONS MAINLY ALONG THE
INTERIOR SLOPES OF THE BIG ISLAND.
