Hawaiian Islands Satellite Interpretation Message
Sat, 25 Sep 2010 00:30:00 -0500
Based on data through 0500 UTC September 25 2010.
An area of broken low clouds is almost past the central islands at sunset. The bulk of the clouds now reside over the leeward waters of Oahu to Maui. They gave the central islands some spotty showers earlier today. They continue to move southwest, further away from the main Hawaiian islands. In its wake, low cloud coverage has diminished to scattered to locally broken. The broken coverage pertains to the windward and mountain areas of the smaller islands. The Kona district and adjacent coastal waters of the Big Island south of Kona is heavily overcast this past hour. Elsewhere of the Big Island, the slopes above Hilo, the Puna district and the Kau slopes are generally cloudy as well. Some of these clouds have spread into the adjacent waters south and west of Kilauea Volcano to South Point. The rest of the Big Island is generally fair.
Weather radar loop is detecting widely dispersed showers moving across the windward waters. Many would dissipate upon reaching the windward and mountain areas of the smaller islands. No showers are detected over the leeward waters of the smaller islands, and there are no organized low clouds within 300 miles upwind of the main Hawaiian islands. The low level wind flow is from east to west across the windward waters and northeast to southwest over the leeward waters, blowing at 15 to 20 mph.
About 670 mile southwest of Oahu, is a small cluster of thunderstorms associated with a low. A short distance to the southeast of the low, is a 300 mile wide band of clouds with isolated thunderstorms. This band marks the intertropical convergence zone /itcz/ which extends from 08°N 160°W to 08°N 140°W.
