Hawaiian Islands Satellite Interpretation Message

Hawaiian Islands Satellite Interpretation Message
Tue, 25 Jan 2011 23:00:00 -0600

Based on data through 0430 UTC January 26 2011.

Low clouds blanket the Big Island this early evening, except for the highest elevations of Mauna Kea and Mauna Loa. Low ceilings are also prevalent over the slopes of Haleakala in east Maui. Skies are otherwise clear to partly cloudy around the island chain. Low cloud motion is from the north to northeast at 10 mph or less across the aloha state.

A large area of broken low clouds, some with embedded light showers, exists immediately south clockwise through west of the Big Island. Low clouds collapsing off the isle are also causing ceilings just northeast and east of the Hilo and Puna districts. Elsewhere conditions are virtually clear in the adjacent coastal waters.

The leading edge of broken to overcast low clouds with a front is about 100 miles northwest of Kauai as of bulletin time, and has been heading east and southeast at 10 to 15 mph. Most of the clouds with the boundary are currently northwest and north of a line from 30°N 151°W to 26°N 156°W to 21°N 166°W to 18.5°N 180°.

The combination of a surface trough and upper trough is generating showers and isolated thunderstorms far east-southeast of the Big Island. At the moment, most of the convection is located from 12°N to 17°N between 136°W and 147.5°W. The troughs have been nearly stationary.
