Hawaiian Islands Satellite Interpretation Message
Mon, 18 Oct 2010 19:30:00 -0500
Based on data through 0000 UTC October 19 2010.
Cloud cover has increased considerably over the main Hawaiian islands since late last night, especially over the Big Island of Hawaii.
Overcast clouds cover most of the Big Island. These clouds extend upslope almost to the summits of Mauna Kea and Mauna Loa. Clouds remain scattered over the summits of the two big volcanoes and near Cape Kumukahi, near South Point and along the coast and lower slopes from kiholo to Upolu Point. Broken to overcast clouds also cover most of east Maui with scattered clouds along the coast. Clouds remain scattered over most areas of the islands from central Maui to Niihau but there are patchy broken low clouds over mauka areas of west Maui, Lanai, Molokai and Oahu, and over the west slopes of Kauai and Niihau.
Clouds are very isolated over water around the islands. Low clouds near the islands are moving from slightly south of east at 10 mph.
An area of showery broken to overcast low clouds and embedded cumulonimbus clouds, cb, is south and east of a line from 23°N 140°W to 26°N 144°W to 125 miles southeast of the Big Island to 14°N 160°W. The closest cb are about 220 miles southeast of the Big Island. This cloud area has been moving toward the west at 10 mph.
A frontal cloud band lines northwest of a line from 36°N 150°W to 32°N 160°W to 30.5°N 170°W to 31°N 180°W. The frontal band is 150 miles wide and contains showery overcast low clouds and scattered towering cumulus clouds.tcu. The part of the band between 160°W and 170°W has moved south slowly since this morning while the part west of 170°W has been nearly stationary. A prefrontal convergence band is centered from 32°N 155°W, where it merges with the frontal band, to 27°N 170°W. The part of the band east of 165°W is 150 miles wide and contains deep overcast layered clouds and isolated cumulonimbus clouds, cb, with tops to 35000 ft. The part of the band west of 165°W contains showery broken low clouds. The part of the convergence band north of the islands has moved southeast at 20 mph over the past 6 hours.
Water vapor imagery, which shows features mainly above 24000 ft, shows a trough aloft from 30°N 145°W to just northwest of Kauai to 20°N 180°W. The trough has been moving toward the southeast at 20 mph over the past 12 hours.
