HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
1830 UTC SUN FEB 01 2015

BASED ON DATA THROUGH 1800 UTC FEBRUARY 01 2015

TWO FRONTS WERE LYING NORTH OF THE ISLANDS THIS MORNING.  ONE WAS
WEAKENING ABOUT 300 MILES NORTH OF KAUAI.  THE SOUTH EDGE OF THE
ASSOCIATED FRONTAL CLOUD BAND STRETCHED THROUGH 30N 149W TO 27N 160W
TO NEAR 28N 170W.  THIS PART OF THE CLOUD BAND...SOUTH OF 30N
LATITUDE...WAS ABOUT 150 MILES WIDE AND CONSISTED MOSTLY OF BROKEN
LOW CLOUDS.  THE CLOUD BAND WAS BEING GREATLY OBSCURED FROM ABOVE BY
A SWATH OF BROKEN TO OVERCAST CIRRUS CLOUDS FLOWING EASTWARD OVER
THIS FRONT.  THE FRONTAL BAND WAS MOVING EAST NEAR 10 MILES AN HOUR.

A SECOND FRONTAL CLOUD BAND...OR THE REMNANT OF ONE...CONTINUED TO
DISSIPATE IMMEDIATELY NORTH OF KAUAI.  THIS DECAYING CLOUD BAND WAS
ROUGHLY 175 MILES WIDE DUE TO THE SPREADING OUT OF THE CLOUD
FRAGMENTS WITHIN IN IT.  THE FRAGMENTED...BROKEN TO OVERCAST BAND
WAS CENTERED ALONG A LINE FROM 25N 150W TO 23N 155W TO 22N 175W.
THE NORTHEAST EXTENT OF THIS BAND APPEARED TO STILL BE INTACT AND
MORE ACTIVE AS IT STRETCHED FROM 25N 150W THROUGH 30N 144W.
ISOLATED THUNDERSTORMS WERE FORMING ALONG THIS BAND JUST NORTH OF
30N LATITUDE.

A SWATH OF CIRRUS ORIGINATING FROM JUST WEST OF THE DATELINE WAS
FLOWING EASTWARD TO NEAR 150W LONGITUDE.  THIS AREA OF BROKEN TO
OVERCAST HIGH CLOUDS COVERED MUCH OF THE AREA FROM 20N TO 30N
BETWEEN 180E AND 160W.  MOSTLY BROKEN CIRRUS OCCUPIED THE AREA FROM
25N TO 30N BETWEEN 160W AND 145W.  A FEW SMALL STRANDS OF CIRRUS
WERE OCCASIONALLY MAKING THEIR WAY OVER KAUAI.

AT 8 AM...BROKEN TO OVERCAST LOW CLOUDS COVERED MUCH OF THE
SOUTHEAST SIDE OF THE BIG ISLAND FROM HILO TO THE PUNA AND KAU
DISTRICTS.  A LARGE CLUSTER OF MOSTLY OVERCAST LOW CLOUDS NORTHEAST
OF MAUI COUNTY WAS PRODUCING CLOUD SKIES OVER LANAI...THE EAST HALF
OF MOLOKAI AND MOST OF MAUI EXCEPT FOR A SMALL SOUTH SECTION BETWEEN
HANA AND MAKENA.  OAHU WAS SUNNY FOR THE MOST PART.  AND KAUAI WAS
MOSTLY CLOUDY BUT MAINLY DUE TO HIGH LEVEL CIRRUS CLOUDS.

THE LOW CLOUDS SEEN EAST OF MAUI OR NORTHEAST OF THE BIG ISLAND WERE
FLOWING NORTHWESTWARD.  THOSE LOW CLOUDS EAST...SOUTH AND WEST OF
THE BIG ISLANDS WERE MOVING DUE WEST.
