Visible satellite imagery shows a decaying 200 mile-wide cloud band of mainly cumulus and stratocumulus clouds associated with a former sfc frontal boundary extending from 21.2°N 140.0°W to 15.3°N 148.6°W. Cloud tops were near 7 thousand feet. This band remains nearly stationary.

Closer to the islands, overcast low clouds cover all of the windward areas/slopes of the Big Island below 7 thousand feet, and including the SE slopes of Mauna Loa down to S point. On the leeward Big Island, broken low clouds linger from S Kohala through Milolii below 6 thousand feet. On Maui county, broken low clouds linger over all the slopes of Haleakala below 7 thousand feet, and over interior areas of the W Maui mountains. Locally broken low clouds also linger over the Molokai E mountains and interior Lanai. On Oahu and Kauai county, broken low clouds prevail with a few passing showers from the N affecting mainly the mountain ranges.

Elsewhere, scattered to locally broken cumulus and stratocumulus clouds cover most of the area N of 10°N. Cloud motion is mainly to the S and SW between 150°W and 180, turning to the E and NE from 140°W to 150°W.

Far S of the islands, vigorous thunderstorm activity cover most of the intertropical convergence zone, or ITCZ, between the equator and 10°N. Cloud tops ranged from 45 to 55 thousand feet.
