HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
1230 UTC WED APR 23 2014

BASED ON DATA THROUGH 1200 UTC APRIL 23 2014

WATER VAPOR IMAGES SHOWED A BROAD AREA OF LOW PRESSURE IN THE MIDDLE
ATMOSPHERE OVER...AND TO THE SOUTHWEST THROUGH WEST...OF THE MAIN
HAWAIIAN ISLANDS. HIGH TO MIDDLE CLOUD LAYERS FORMED UNDER THIS
FEATURE WITHIN 75 MILES OF THE CURVE FROM 24N 158W TO 21N 158W TO
19N 160W. THE LOW ALSO PULLED HIGH TO MIDDLE CLOUD LAYERS OUT OF THE
ITCZ FURTHER SOUTH...PARTLY TO MOSTLY OBSCURING LOWER FEATURES
WITHIN 200 MILES OF THE CURVE FROM 27N 154W TO 21N 149W TO 14N 150W
TO 10N 155W.

TO THE NORTHWEST...LOW TO MIDDLE CLOUD LAYERS ASSOCIATED WITH A
FRONT COVERED HAWAIIAN WATERS NORTHWEST OF THE LINE FROM 30N 177W TO
29N 180. THIS FEATURE MOVED NORTHWEST SLOWLY. THINNER HIGH TO MIDDLE
CLOUD LAYERS ORIGINALLY ASSOCIATED WITH THE FRONT NOW PARTLY TO
MOSTLY OBSCURED LOWER FEATURES WITHIN 150 MILES OF THE CURVE FROM
30N 158W TO 24N 167W TO 19N 178W.

TO THE SOUTH...LIGHT THUNDERSTORM ACTIVITY CONTINUED IN THE ITCZ
FROM 09N TO 01N. LAYERED DEBRIS CLOUDS FROM THIS AND EARLIER
CONVECTION MOSTLY TO PARTLY OBSCURED LOWER FEATURES FROM 11N TO THE
EQUATOR...AND ALSO WRAPPED AROUND THE MID-LEVEL LOW FURTHER NORTH AS
DESCRIBED IN THE FIRST PARAGRAPH.

OTHERWISE...CLOUD COVER ACROSS HAWAIIAN WATERS CONSISTED MAINLY OF
MODERATELY TO DENSELY PACKED MARINE STRATOCUMULI AND CUMULI MERGING
INTO AREAS OF NEARLY SOLID LOW STRATUS OVERCAST. INDIVIDUAL SMALL
CUMULI ALSO WERE PRESENT THROUGHOUT. THESE CLOUDS WERE GREATEST IN
AREAL COVERAGE NORTH OF 20N AND EAST OF 160W...AND INCREASED IN
AREAL COVERAGE SUBSTANTIALLY WITH TIME OVER THE PAST SIX HOURS TO
THE EAST OF 150W. THEY GENERALLY ROSE TO HEIGHTS OF 8000 TO 10000
FEET...AND MOVED TOWARD THE WEST SOUTHWEST AT 15 TO 20 MILES AN HOUR.

ACROSS THE MAIN HAWAIIAN ISLANDS...HIGH TO MIDDLE CLOUD LAYERS
ASSOCIATED WITH THE MID-LEVEL LOW PARTLY OBSCURED LOWER FEATURES.
WHERE IT WAS VISIBLE...LOWER CLOUD COVER CONSISTED MOSTLY OF MARINE
STRATOCUMULI MOVING ASHORE ALONG SLOPES FACING EAST. LAYERED DEBRIS
CLOUDS FROM AFTERNOON CUMULUS BUILDUPS ON TUESDAY LARGELY HAD
DISSIPATED. THESE LOWER CLOUDS VARIED IN HEIGHT FROM 6000 TO 10000
FEET. RADAR DATA FROM NEAR THE ISLANDS SHOWED SCATTERED SHOWERS
OFFSHORE TO THE SOUTHEAST OF THE BIG ISLAND...BUT ISOLATED SHOWERS
AT MOST ELSEWHERE.

NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
0030 UTC WED APR 23 2014

BASED ON DATA THROUGH 0000 UTC APRIL 23 2014

WATER VAPOR IMAGERY SHOWED A PERSISTENT UPPER LEVEL LOW JUST A FEW
MILES NORTH OF NIIHAU EARLY THIS TUESDAY AFTERNOON.  THE LOW
APPEARED TO BE NEARLY STATIONARY.  IT WAS SPREADING SEVERAL SMALL
CLUSTERS OF BROKEN TO OVERCAST CIRRUS CLOUDS OVER THE AREA FROM 21N
TO 24N BETWEEN 159W AND 161W.  THUS WHILE THE CIRRUS WAS AFFECTING
KAUAI AND NIIHAU...THE REST OF THE STATE WAS VOID OF HIGH CLOUDS.

A RAGGED STREAM OF BROKEN CIRRUS CLOUDS FLOWING UP FROM THE DEEPER
TROPICS WAS PASSING JUST EAST OF THE BIG ISLAND.  THE STREAM WAS
CENTERED ALONG A LINE FROM 10N 10W TO 20N 152W TO 23N 145W.  IT WAS
ABOUT 100 MILES WIDE AT 10N AND GRADUALLY WIDENED TO 170 MILES
ACROSS EAST OF THE BIG ISLAND.  FROM THERE IT SPREAD OUT TO NEAR
240 MILES WIDE AS IT CONTINUED NORTHEASTWARD.

STURDY TRADE WINDS CONTINUED TO SWEEP RANDOMLY SCATTERED CLUSTERS
AND PATCHES OF LOW CLOUDS THROUGH THE ISLANDS.  THESE LOW CLOUDS
WERE MOVING WEST AROUND 30 MILES AN HOUR.  AT 2 PM...SKIES WERE
MOSTLY CLOUDY OVER KAUAI AND NIIHAU.  SOME BROKEN LOW CLOUDS LINED
THE WINDWARD SIDE OF THE BIG ISLAND AND THE KOOLAU MOUNTAINS ON
OAHU AS WELL AS THE EAST PARTS OF MAUI AND MOLOKAI.  BUT THE
MAJORITY OF THE STATE WAS SUNNY TO MOSTLY SUNNY.

IN THE DISTANCE...A LARGE BAND OF CIRRUS STRETCHED FROM WEST TO
NORTH OF THE STATE.  THE CIRRUS BAND WAS ROUGHLY 150 MILES WIDE.
THE SOUTH EDGE OF THE BAND EXTENDED THROUGH 22N 180E TO 25N 170W
TO 27N 165W THROUGH 30N 162W.  THIS BAND WAS DRIFTING SLOWLY
EASTWARD.

PASSING OVER THE EAST HALF OF THE BIG ISLAND.

AN UPPER TROUGH EXTENDED SOUTHWEST FROM THE UPPER LOW TO NEAR 14N
167W.  SOUTHERLY WINDS EAST OF THE TROUGH WERE CARRYING A SWATH OF
BROKEN CIRRUS CLOUDS NORTHWARD.  THE CIRRUS SWATH WAS MOSTLY 175 TO
200 MILES WIDE AND CENTERED ALONG A LINE FROM 13N 156W TO 17N 154W
TO 22N 148W.  THUS A SMALL AMOUNT OF CIRRUS ALONG THE WEST EDGE OF
THE SWATH WAS SKIRTING THE BIG ISLAND NOW AND THEN.

STURDAY TRADE WINDS CONTINUED TO SWEEP NUMEROUS...RANDOMLY
DISTRIBUTED...SMALL CLUSTERS AND PATCHES OF LOW CLOUDS THROUGH THE
ISLANDS.  THESE LOW CLOUDS WERE MOVING WEST AROUND 30 MILES AN
HOUR.  AT 8 AM... SKIES WERE CLOUDY OVER THE VAST MAJORITY OF KAUAI
AND NIIHAU.  CLOUDY SKIES ALSO LINED THE WINDWARD COASTS OF THE BIG
ISLAND AND THE EAST AND NORTHEAST TIPS OF MAUI AND MOLOKAI.  THE
REST OF THE STATE WAS MOSTLY SUNNY.

OFF TO THE NORTHWEST...A LARGE BAND OF MULTI LAYERED CLOUDS....
ASSOCIATED WITH A FRONT...WAS SLOWLY APPROACHING THE STATE.  THE
EAST EDGE OF THE ROUGHLY 200 MILES WIDE BAND EXTENDED THROUGH 30N
162W TO 26N 167W TO 22N 180E.  THE FRONT IS EXPECTED TO MOVE
