Issued: Aug 30, 2014 2:30 PM HST

Based on data through 2:00 pm Aug 30 2014 HST

Weak surface high pressure north of the state continued to result in light trade winds across the Hawaiian island region this afternoon. Numerous though widely separated patches of scattered low clouds along with a few embedded clusters of broken low clouds were meandering westward through the region. The low clouds near the islands were moving along near 12 miles an hour.

A weak low level vortex or low cloud circulation center was skirting the northeast coast of Molokai. Broken low clouds associated with this weak system were mostly between 90 and 200 miles northeast of Molokai. The presence of this weak circulation and the light trades allowed some clouds to form over Maui county from midday.

At 2 pm, broken to overcast low clouds had gathered over most of the inland slopes surrounding the Big Island. The immediate coastlines and the highest elevations in the interior of the island remained mostly sunny. Molokai and Lanai were mostly cloudy. Maui and Kauai had just about an even mix of cloudy and sunny skies. Skies over Oahu were nearly all sunny to mostly sunny.
