The main cloud feature around the main Hawaiian islands is a band of clouds which are the mangled remnants of an old front. The band extends from near 27°N 140°W to 22°N 150°W across the Big Island to 19°N 160°W. The band has been moving toward the south southeast at 5 to 10 mph.
Cloud coverage over the islands themselves varied from island to island but has increased since this morning. Over Kauai low clouds are covering most interior areas with scattered low clouds seen elsewhere. Over Oahu low clouds are banked up over the slopes and summits of both the Koolau and Waianae mountain ranges with scattered low clouds seen over leeward and interior areas. Just a few patches of low clouds are seen over interior Molokai and Lanai. Over Maui low clouds are banked up over the slopes of Haleakala as well as over the slopes and summits of the west Maui mountains. Over the Big Island the above mentioned cloud band along with daytime heating has caused most of the Big Island to become covered in clouds. Cloud tops over the Big Island are estimated to be up to around 25000 feet.
A couple of areas of deep convection are noted along the ITCZ. The first area is centered about 900 miles southeast of the Big Island while a second area lies about 1150 miles southwest of Honolulu. These areas have been nearly stationary over the past several hours.
