Hawaiian Islands Satellite Interpretation Message

Hawaiian Islands Satellite Interpretation Message
Fri, 24 Sep 2010 13:30:00 -0500

Based on data through 1800 UTC September 24 2010.

Patches of broken low clouds are moving west across Kauai and across windward sections of Maui and the Big Island, as well as across windward waters adjacent to those islands. Skies are generally scattered elsewhere across the main Hawaiian islands. The patch of broken low clouds across Kauai affects its eastern two-thirds. The eastern tip of Maui has broken low clouds while windward slopes of the Big Island have broken to overcast low clouds from Hilo northward.

Satellite loop shows the subtropical ridge extends roughly through 30°N 140°W, 26°N 160°W and 26°N 170°W. Trade flow along the southern flank of the ridge is rather sluggish west of 150°W, with low clouds moving west at 10 to 15 mph across the main Hawaiian islands. Farther to the north, a 90 to 150 mile wide band of broken to overcast layered clouds extends north and west of a line from 43°N 140°W to 36°N 150°W to 34°N 160°W to 32°N 170°W to 33°N 180°W. Marking a frontal boundary, this cloud band is moving toward the east at 30 to 40 mph along 40°N. Movement is more toward the southeast and south at 10 mph or less west of 160°W.

To the south, isolated cumulonimbus, cb, mark the intertropical convergence zone within a 120 mile wide arc from 08°N 140°W to 09°N 160°W to 12°N 170°W to 08°N 180°W. A weak tropical disturbance near 13.5°N 161.2°W is moving west at about 10 mph. A single cb lies just northeast of the center of circulation.
