Issued: Sep 02, 2014 2:30 AM HST

Based on data through 2:00 am Sep 02 2014 HST

An area of broken showery cumulus and stratocumulus is associated with a low level trough SW of Oahu. The cluster of clouds is located about 230 miles SW of Honolulu, with cloud tops reaching 20 thousand feet, and moving W at about 15 mph. Another area of showery cumulus clouds is moving into the windward Big Island coastline with cloud tops around 12 thousand feet.

On the Big Island, a line of broken low clouds extends across windward coastal locations from Kapoho to Waipio valley. The rest of the Big Island remains mainly under scattered low clouds. On Maui county, mainly scattered low clouds prevail except for patches of locally broken low clouds moving across windward areas of Maui from hamoa to Haiku, the W Maui mountains and portions of N Molokai. On Oahu, scattered low clouds prevail except for some lingering patches of broken low clouds with a few showers across the Koolau mountains. On Kauai county, localized broken low clouds still linger over interior and N Kauai.

Elsewhere, scattered cumulus and stratocumulus clouds cover the area between 140°W to 155°W, becoming locally broken W of 155°W. Individual cloud elements are moving w/nw at about 15 mph. Latest water vapor imagery depict an upper level trough about 490 miles NE of Midway atoll, gradually migrating E at 15 to 20 mph. This trough is supporting an area of layered clouds and active thunderstorms around 760 miles NW of Kauai with highest cloud tops around 42 thousand feet.

Far S of the islands, a very active pattern can be observed along the intertropical convergence zone, or ITCZ, with broken to overcast layered clouds and large clusters of active thunderstorms spreading between 04°N to 12°N and 150°W to 180. Highest cloud tops are pushing 56 thousand feet.
