Issued: Jul 28, 2014 8:30 AM HST


Based on data through 8:00 am Jul 28 2014 HST


Water vapor imagery showed a weak upper low near 29°N 155°W. A shallow upper trough extended from the low to 24°N 159°W. The low and trough were moving slowly east southeastward.

The upper level winds from the southwest were carrying a 225 miles wide swath of mostly broken cirrus clouds northeast across the Big Island. This swath was centered along a line from 15°N 160°W to 20°N 152°W to 21°N 146°W. These high clouds over the Big Island, along the northern edge of the swath, were fairly thin and not blocking out much sunshine.

The prevailing trade winds were carrying small clusters of mostly broken low clouds into the Big Island this morning. Only patches of scattered low clouds were noted around the other islands. However, a larger batch of low clouds had gathered along the east and northeast coasts of Maui. At 8 am, skies were mostly cloudy along the windward side of the Big Island. Partly cloudy to mostly cloudy skies were of the northeast half of Oahu and the east tip of Maui. The rest of the state had mostly sunny skies.

Numerous scattered thunderstorms continued to erupt along the tropical areas south of the islands. A roughly 450 miles wide swath of broken to overcast layered clouds and scattered thunderstorms Sat from 07.5°N to 15°N between 140°W and 160°W, and from 03.5°N to 10°N between 160°W and the dateline. The remnant of former tropical depression Genevieve was embedded within the large area of clouds and thunderstorms located about 730 miles southeast of Hilo.
