Hawaiian Islands Satellite Interpretation Message

Hawaiian Islands Satellite Interpretation Message
Wed, 29 Sep 2010 13:00:00 -0500

Based on data through 1730 UTC September 29 2010.

Skies are clear to occasionally partly cloudy across the island chain this morning. Low cloud movement is from the northeast to east-northeast near 15 mph statewide.

A weakening front, with scattered to occasionally broken low cloudiness and which appears nearly stationary, lies just north of the islands at the moment. Some of the clouds associated with the boundary are just north clockwise through east of Kauai, north and east of Oahu, and north of Maui county. More concentrated cloudiness with the front extends far northeast and northwest from the state. Plume clouds are generating low ceilings from time to time immediately west of Kona on the Big Island. Conditions are clear to scattered elsewhere over the adjacent coastal waters.

In the upper air above 25 thousand feet, a low is centered about 1050 miles west of Kauai and has been heading toward the west or northwest near 10 mph over the past six hours. An area of showers and thunderstorms with the low is mainly located from 21.5°N to 27°N between 174.5°W and 178°E. South of the low, more instability aloft is helping to ignite convection from 09°N to 15°N between 172°W and the date line at 180.

Unorganized showers and thunderstorms are firing along the intertropical convergence zone far south of Hawaii. Most of the activity is found from 09°N to 14°N between 133°W and 143°W, and from 07°N to 12°N between 153°W and 163°W.
