Hawaiian Islands Satellite Interpretation Message
Sat, 16 Oct 2010 07:30:00 -0500
Based on data through 1200 UTC October 16 2010.
Water vapor imagery continues to show a broad upper level trough over the main Hawaiian islands overnight. This upper level trough continues to trigger isolated thunderstorms not that far from the main Hawaiian islands. One area of isolated thunderstorms is about 300 miles west southwest of Kauai at 2 am, with another area of isolated thunderstorms about 400 to 600 miles northwest of the garden isle. High clouds are streaming over the portions of Maui county and the Big Island from the southwest in the upper level wind flow. The high clouds over the Big Island are obscuring lower clouds over the island at 2 am.
Niihau is cloud free at 2 am. Scattered clouds are found over Kauai overnight, with the heaviest concentration on the eastern side of the island. On Oahu, clouds blanket much of the Koolau range and the adjacent coastal areas, with the northern half of the koolau's seeing the heaviest concentration of clouds. Just a few clouds are found over Molokai and Lanai at 2 am. High clouds passing over Kahoolawe are making it difficult on satellite to discern lower clouds over the island, but satellite loops suggest just a few lower clouds over the island at 2 am. Low clouds have decreased over Maui since sunset, with scattered clouds found over the east facing slopes of the west Maui mountains and the east facing slopes of Haleakala.
Low clouds upstream of the islands are moving in from east northeast around 15 mph.
