Scattered clouds were found over the eastern half of Kauai at 8 am, while scattered clouds were found over the east facing slopes and adjacent coastline of the Koolau range on Oahu. A few clouds were found over the eastern third of Molokai, while Lanai and Kahoolawe had just a cloud or two overhead. Maui is virtually cloud free at 8 am with just a couple clouds over the west Maui mountains, and over the east facing slopes of Haleakala above Hana. On the Big Island, clouds are found over the east facing slopes of the Kohala mountains and over the east facing slopes of the north Hilo, south Hilo, and Puna districts. A few clouds are found over the lower slopes of the Kau and and north Kona districts.
Scattered low clouds are found within 40 miles to the northeast of the islands. Between 40 and 300 miles to the northeast, coverage increases with areas of broken cumulus. Low clouds upstream of the islands are moving in from the east northeast around 15 mph.
High clouds are found to the northwest of Kauai, mainly over the northwest islands from Nihoa to laysan. The high clouds are not thick enough to obscure the lower clouds in this area, which appear to be scattered in nature.
About 300 miles south of the Big Island is an area of towering cumulus reaching near 52000 feet. Another area is about 400 miles southwest of the Big Island with tops near 46000 feet.
