HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
1210 UTC SAT MAY 28 2016

BASED ON DATA THROUGH 1200 UTC MAY 28 2016

AT 200 AM HST...WATER VAPOR IMAGERY SHOWED A BROAD UPPER TROUGH
EXTENDING SOUTHWEST ACROSS THE DISCUSSION AREA THAT WAS LOCATED WEST
AND NORTHWEST OF KAUAI. THIS UPPER TROUGH COMBINED WITH A SURFACE
TROUGH CONTINUED TO SUPPORT AN ACTIVE LINE OF TOWERING CUMULUS AND
CUMULONIMBUS CLOUDS THAT EXTENDED SOUTHWEST WELL NORTH OF KAUAI FROM
30N 156W TO 26N 161W. CLOUD TOPS ASSOCIATED WITH THESE CLOUDS
REACHED 35 TO 40 THOUSAND FEET. THIS LINE WAS SLOWLY SHIFTING TOWARD
THE EAST. ADDITIONALLY...PLENTY OF HIGH CLOUDS WERE BEING PULLED
NORTHWARD ACROSS A LARGE AREA EAST OF THIS UPPER TROUGH THAT
INCLUDED MAUI AND THE BIG ISLAND. THESE HIGH CLOUDS OR DEBRIS CLOUDS
WERE FROM THUNDERSTORMS THAT HAD DEVELOPED WELL SOUTH OF THE STATE
AROUND 10N FROM 150W TO THE DATE LINE WITHIN THE INTERTROPICAL
CONVERGENCE ZONE.

MOST OF THE CLOUD COVERAGE ACROSS KAUAI WAS FOCUSING OVER THE
INTERIOR AREAS...LEAVING ISOLATED TO SCATTERED COVERAGE OVER THE
REST OF THE ISLAND. A SMALL BATCH OF LOW CLOUDS WAS PUSHING OVER THE
NORTHERN SECTION OF NIIHAU. SCATTERED TO BROKEN LOW CLOUDS WERE
SETTING UP OVER THE WINDWARD LOCATIONS OF OAHU WITH ISOLATED CLOUD
COVERAGE ELSEWHERE OVER THE ISLAND. BROKEN LOW CLOUDS WERE SHOWN
OVER THE EASTERN HALF OF MOLOKAI WITH MOSTLY CLEAR SKIES SHOWN OVER
THE WESTERN HALF. BROKEN TO OVERCAST LAYERED CLOUDS WERE SHOWN OVER
MAUI AND THE BIG ISLAND...MAINLY DUE TO THE AFOREMENTIONED HIGH
CLOUDS STREAMING FROM SOUTHWEST TO NORTHEAST...WHICH WERE COMPLETELY
OBSCURING ANY LOW CLOUDS FROM BEING SHOWN OVER THE BIG ISLAND.
