MOVING UP OVER THE BIG ISLAND ESPECIALLY OVER SOUTHERN AND EASTERN
SECTIONS. THE OVERALL TREND OF THESE HIGH CLOUDS IS SHOWING A
WESTWARD DRIFT TO THEM.

SCATTERED TO LOCALLY BROKEN LOW CLOUDS ARE SEEN MOVING WESTWARD IN A
MODERATE TRADE WIND ENVIRONMENT. THIS IS PRIMARILY CAUSING A TYPICAL

AREAS WHILE MOST LEEWARD LOCATIONS BEING CLOUD FREE. OVER OAHU LOW

NORTHERN AND EASTERN SLOPES OF HALEAKALA AS WELL AS OVER THE SLOPES
AND SUMMITS OF THE WEST MAUI MOUNTAINS. OVER THE BIG ISLAND LOW
