At 200 am HST, satellite imagery showed a large area of broken to overcast layered clouds associated with hurricane madeline between the Big Island and 140°W from 15°N to 28°N. Embedded thunderstorms were shown within 100 miles of the eye of hurricane madeline that was centered around 515 miles east of Hilo. Maximum cloud tops associated with these storms extended to around 50 thousand feet. Madeline was tracking toward the west-northwest at 10 mph. The western edge of this large area of cloud coverage was moving over the windward Big Island waters.

Scattered to broken layered clouds with a few embedded thunderstorms were shown a few hundred miles southwest of Oahu. These clouds were associated with a weak low pressure that was tracking toward the west-northwest. Maximum cloud tops extended to around 45 to 50 thousand feet. Scattered debris or high clouds associated with these thunderstorms were shown lifting north and northeast over Kauai and Oahu.

Broken to overcast layered clouds, mostly upper clouds, associated with an upper trough and surface frontal boundary were shown over the far northwest section of the discussion area, which was several hundred miles northwest of Kauai. This area of clouds was slowly tracking toward the east.

Scattered cumulus clouds were shown over and around the main Hawaiian islands tracking toward the west-southwest within the trade winds south of high pressure. Scattered high clouds that were lifting northward over Oahu and Kauai combined with the low-level clouds were translating to mostly cloudy conditions. Elsewhere, much of these low clouds were focusing over the windward locations of each island, with only a few clouds managing to spill over to the leeward areas.
