Issued: May 21, 2013 7:30 PM HST


Based on data through 7:00 pm May 21 2013 HST


Water vapor imagery depicts an upper low near 31°N 155.6°W, about 685 miles north of Honolulu at 7 pm. This low has been lifting north over the last several hours. Thunderstorms had diminished near the upper level low over the last several hours. Thin high clouds have passed over the main Hawaiian islands at times in the upper level wind pattern, from southwest to northeast. As of 7 pm, just a few thin wisps are noted. Another upper level low is near 15°N 178°E, about 1640 miles west southwest of Honolulu, and has been nearly stationary.

The last visible imagery of the day shows plenty of clouds covering the Big Island, extending up the slopes to around 10000 feet. Kauai also has plenty of clouds overhead, with clouds covering most of the garden isle and extending about 45 miles north northeast of the island. On Oahu, clouds are concentrated on the northern half of the island. Molokai has a few clouds over the eastern end of the island while Lanai has a few over the interior of the island. Scattered clouds are found over the west Maui mountains, with additional clouds found over the Haleakala slopes. The clouds over Haleakala are thickest over the northwestern side of the mountain.
