Hawaiian Islands Satellite Interpretation Message
Wed, 22 Dec 2010 12:30:00 -0600
Based on data through 1800 UTC December 22 2010.
Water vapor imagery shows a broad upper trough over the central Pacific, with a number of embedded shortwave troughs moving across the region. One upper level trough is located near 25°N 159°W, or about 200 miles north of Kauai. This shortwave is moving to the east at 25 mph. A cloud band associated with a dissipating front is located near the shortwave, or just northeast of the main Hawaiian islands. The band is up to 400 miles wide, and the western edge extends from 30°N 165°W to 23°N 158°W to 16°N 151°W. The band is composed primarily of overcast cumulus and stratocumulus elements, but with areas of mixed layered clouds along the western edge. One area of deeper clouds is located ahead of the shortwave, beginning about 100 miles northeast of Kauai. Broken layered clouds with embedded cumulonimbus elements are located along the western edge of the cloud band generally between 149°W and 159°W. Cloud tops extend up to 40000 ft.
Another upper level trough is located near 15°N 155°W, or about 250 miles south of the Big Island. This trough is moving to the east southeast at 15 mph. Isolated cumulonimbus clouds are located east of this trough, and are located generally from 14°N to 16°N between 148°W and 151°W. Convective cloud tops extend up to 44000 ft. The cumulonimbus clouds are moving to the east northeast at 10 to 15 mph, while nearby cirrus clouds are moving to the east at 40 mph.
A third upper level trough is located near 21°N 173°W, or about 600 miles south southeast of Midway atoll. This trough is moving to the east northeast at 30 mph. Isolated cumulonimbus clouds are located east of this trough, generally from 19°N to 23°N between 166°W and 173°W. Individual cumulonimbus clouds are moving to the east northeast at 15 to 20 mph. Broken to overcast cirrus and cirrostratus clouds are located through this area as well. These high clouds are moving to the east and northeast at 30 to 40 mph.
Farther west, a larger area of broken to overcast layered clouds is located north of 14°N along the international dateline. Scattered cumulonimbus clouds are embedded within this line. Cloud tops extend up to 48000 ft. Broken cirrus and cirrocumulus elements extend east from the main area of layered clouds, generally as far east as 174°W.
Across the main Hawaiian islands, scattered to broken low clouds are located near the eastern and southern coast of Kauai, with clear skies across the interior of the island. Broken low clouds cover the south shore of Oahu, and southeast sections of the island east of Pearl Harbor and south of Kaneohe bay. These clouds extend offshore across the Kaiwi Channel, and also cover Lanai and western and southern sections of Molokai. Broken low clouds cover the coastal sections and central valley on Maui, and also extend across the Alenuihaha channel.
On the Big Island, broken to overcast low clouds cover north and south Kohala districts, with scattered to broken low clouds across Hamakua and north Hilo districts below 8000 ft. Broken low and middle level clouds cover south Hilo and Puna districts. Scattered to broken low clouds are located over north and south Kona and Kau districts generally below 4000 ft.
