Hawaiian Islands Satellite Interpretation Message
Sun, 31 Oct 2010 13:30:00 -0500
Based on data through 1800 UTC October 31 2010.
An area of showery low clouds is over windward waters east of the Big Island and Maui, moving westward toward the islands in a light to moderate trade wind flow. Immediately upstream of the other islands however, including the near shore windward waters east of Maui, have few low clouds, with isolated patches of scattered low clouds.
Windward portions of the island of Kauai have scattered to broken stable cumulus /cu/ banked along the slopes of Mount Waialeale, while leeward portions of the island, and all of Niihau, are under sunny skies this morning. A narrow ribbon of scattered low clouds lines the summit of the Koolau range on Oahu this morning, otherwise skies are sunny over the remainder of Oahu, and near shore waters. Scattered to locally broken patches of cu are seen along the lower windward slopes of eastern Molokai, and over the slopes of Maui, but sunny skies prevail over the bulk of Maui county. Windward Big Island, in contrast, is mostly cloudy with a mix of showery cu and stable stratocumulus /sc/, with the Big Island on the eastern edge of an area of broken low clouds that extends up to 300 miles to the east. The leeward side of the Big Island, and interior portions of the island, are under sunny skies. Low clouds near the islands are moving toward the west at speeds near 15 mph, with the leading edge of the clump of showery low clouds about 100 miles east of windward Haleakala.
An area of broken high clouds is west of the islands this morning, with these high clouds associated with a narrow NE to SW oriented low aloft that is centered about 800 miles west of Kauai, near 23°N 172°W. High clouds are forming within the diffluent flow aloft on the southeast portion of the low, but are dissipating before moving over the islands, where a ridge aloft is in place.
Isolated thunderstorms lack significant organization within the near equatorial trade wind convergence zone south of the islands, and are most concentrated from 6°N to 10°N between 145°W and 174°W.
