This system continues to lift to the north and east, moving away from the islands overnight.

Similarly.scattered to broken low clouds remain over the northern and western portions of Oahu, and over the adjacent waters. A few clouds are found over the northern half of Kauai, and few to scattered clouds are found over the Koolau range on Oahu.
The clouds near and over the islands of Maui county at sunset have all but disappeared. Just a few clouds are noted over Maui county at 2 am. Similarly, the clouds over the Big Island have dissipated significantly since sunset. It appears on infrared imagery that scattered clouds remain over the Kau and south Kona districts, with just a few clouds elsewhere.
