Issued: Jul 23, 2014 8:30 AM HST


Based on data through 8:00 am Jul 23 2014 HST


Water vapor imagery shows a northeast through southwest upper level trough with two embedded lows within it. One low is centered about 500 miles north of Kauai while a second low is centered about 1000 miles west northwest of Kauai. The first low is moving off toward the north northeast while the second low is moving slowly toward the east southeast. Some towering cumulus and isolated thunderstorms are located near the centers of the lows.

Low cloud coverage over the islands varied from island to island but for the most part resembles a typical trade wind scenario. Over Kauai low clouds are covering most eastern and interior areas with just a few clouds seen over some leeward locations. Over Oahu low clouds are banked up over the slopes and summits of both the Koolau and Waianae mountain ranges with the trade winds sufficiently strong enough to blow some scattered low clouds over to leeward areas at times. Just a few patches of low clouds are seen over eastern Molokai and interior Lanai. Over Maui patches of low clouds are seen over the slopes of Haleakala as well as over the slopes and summits of the west Maui mountains. Over the Big Island low clouds are banked up over the windward slopes from north Kohala southward through the Hilo and Puna district, the southeast Kau slopes and over most of the lower Kona and southwest Kau slopes.

An area of disturbed weather along the ITCZ which is about 800 miles south-southeast of the Big Island has become a little more organized overnight. This area of thunderstorms is moving slowly toward the west at the present time. Otherwise just a few widely scattered thunderstorms are seen along the ITCZ which is generally running along 10°N.
