Hawaiian Islands Satellite Interpretation Message
Sat, 27 Nov 2010 18:30:00 -0600
Based on data through 0000 UTC November 28 2010.
Water vapor imagery shows the upper level low near 20°N 147°W, about 510 miles east of the Big Island at 2 pm. Thunderstorms remain active on the north side of the upper low with cloud tops reaching near 41 thousand feet. Additional thunderstorms are found in the ITCZ, and are being drawn northward on the east side of the associated upper level trough. Most of the thunderstorms are within an area bounded by 15.4°N 140.0°W to 8.6°N 134.8°W to 9.0°N 154.6°W with tops reaching near 50 thousand feet.
High clouds are moving over the main Hawaiian islands from the west. These high clouds are associated with an upper level trough to the northwest of the main Hawaiian islands. The trough axis extends from near 30°N 177°W to 19°N 180. The high clouds over Kauai and Niihau are thick enough to at least partially obscure the lower clouds over these islands. Through the use of animated visible imagery, there appears to only be a few areas of clouds over Kauai at 2 pm.
Just a few clouds are found over Oahu, Molokai, Lanai and Kahoolawe at 2 pm. On Maui, the clouds have thinned a bit since sunrise, but remain concentrated over the east facing slopes of the west Maui mountains and Haleakala. On the Big Island, the clouds over the Hilo and Puna districts dissipated by noon, while the clouds over the east facing slopes of the Kohala mountains thickened. Clouds have also built up over the south Kona and north Kona districts in the last several hours.
