Hawaiian Islands Satellite Interpretation Message

Hawaiian Islands Satellite Interpretation Message
Thu, 02 Sep 2010 13:30:00 -0500

Based on data through 1800 UTC September 02 2010.

High pressure far to the north is producing trade winds across the central Pacific. Low clouds moving along with the trades are moving 10 to 20 mph toward the west. An area of broken stratocumulus /sc/ sits between 140°W and 160°W from 20°N to 30°N. West of 160°W, low cloud coverage lessens and transition to sc and cumulus clouds.

Over the islands, trade winds are building up cloud cover over the windward slopes and coasts of the islands. Leeward locations have mostly clear skies. Windward coastal waters have scattered to broken low clouds moving along with the trades with some isolated showers embedded within these clouds. Over leeward waters, skies are mostly clear with the exception of broken cloud cover to the lee of Maui county and the Big Island.

Water vapor imagery shows an upper level trough extending from 15°N and the dateline to 30°N 172°W, and continues to the north. The rest of the subtropical central Pacific is dominated by an upper level ridge.

Far south of the state, isolated thunderstorms stretch across the intertropical convergence zone between 5°N and 12°N.
