HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
0530 UTC SAT MAY 28 2016

BASED ON DATA THROUGH 0500 UTC MAY 28 2016

AT 700 PM HST...WATER VAPOR IMAGERY SHOWED A BROAD UPPER TROUGH
EXTENDING SOUTHWEST ACROSS THE DISCUSSION AREA THAT WAS LOCATED WEST
AND NORTHWEST OF KAUAI. PLENTY OF HIGH CLOUDS WERE BEING PULLING
NORTHWARD ACROSS THE REGION EAST OF THIS UPPER TROUGH THAT INCLUDED
THE BIG ISLAND. THESE HIGH CLOUDS OR DEBRIS CLOUDS WERE FROM
THUNDERSTORMS THAT HAD DEVELOPED WELL SOUTH OF THE STATE BETWEEN 8N
AND 12N FROM 150W TO THE DATE LINE.

SHOWERY BROKEN TO OVERCAST LOW CLOUDS WERE SHOWN OVER EACH OF THE
MAIN HAWAIIAN ISLANDS...ESPECIALLY NIIHAU...KAUAI...OAHU AND THE BIG
ISLAND. MUCH OF THIS CLOUD COVERAGE WAS A RESULT OF THE AFTERNOON
SEA BREEZE THAT SETUP ACROSS THE ISLANDS DUE TO A WEAK TROUGH WEST
OF KAUAI...DAYTIME HEATING...AND A SUFFICIENT AMOUNT OF MOISTURE IN
PLACE. MAXIMUM CLOUD TOPS ASSOCIATED WITH THESE CLOUDS EXTENDED AS
HIGH AS 15 TO 20 THOUSAND FEET. THE CLOUD COVERAGE WAS NOT AS
PRONOUNCED OVER THE MAUI COUNTY ISLANDS IN COMPARISON TO THE OTHERS.
OVERCAST LAYERED CLOUDS WERE SHOWN OVER THE BIG ISLAND DUE TO THE
AFOREMENTIONED HIGH CLOUDS STREAMING FROM SOUTHWEST TO NORTHEAST.
OVER MUCH OF THE MARINE AREAS SURROUNDING THE ISLANDS...ISOLATED TO
SCATTERED LOW CLOUDS WERE SHOWN TRACKING TOWARD THE NORTHWEST AT 5
TO 15 MPH.

AS PREVIOUSLY MENTIONED...ISOLATED TO SCATTERED THUNDERSTORMS WITHIN
THE INTERTROPICAL CONVERGENCE ZONE CONTINUE TO DEVELOP WELL SOUTH OF
THE STATE BETWEEN 8N AND 12N FROM 150W TO THE DATE LINE. THESE
STORMS CONTINUE TO DEVELOP OVER THE SAME GENERAL AREAS WITH CLOUD
TOPS REACHING AS HIGH AS 55 THOUSAND FEET.
