Two upper level lows are noted on water vapor imagery north and northwest of Kauai at 2 am. One low is about 475 miles north northwest of Kauai near 28.4°N 162.8°W. This low has been lifting to the north over the last few hours. The other low is near 28.6°N 175.3°W, about 1065 miles northwest of Kauai. This low has been moving to the southeast over the last several hours.
The high clouds over the eastern islands have thinned since sunset. Most of the high clouds at 2 am are over Maui and the Big Island. The high clouds over Maui are obscuring lower clouds over the slopes of Haleakala, while the high clouds are thin enough over the Big Island to only partially obscure lower clouds.
Low clouds on the Big Island are found along the east facing slopes of the island, and over the southeast facing slopes of the Kau district. As mentioned above, low clouds over the Haleakala slopes are obscured by the higher clouds. Scattered low clouds are over the east facing slopes of the west Maui mountains. Low clouds are found over Lanai, Kahoolawe, and the north shore of Molokai east of kalaupapa. Low clouds have spread across Oahu from the east, and cover the island from the east facing shores to the base of the Waianae range. Low clouds cover Kauai at 2 am.
Low clouds near the islands continue to move in from the east northeast between 20 and 25 mph.
