Looking Ahead

ARTICLE CONTINUES BELOW AD

Flood advisories have been posted for the Hilo side through the night and into early this morning. High moisture and unstable conditions mean the unsettled weather pattern will continue today, with the potential for locally heavy rainfall on Maui and the Big Island. A drier and more stable trade wind weather regime is expected to gradually become established across the Aloha State by late Thursday, and will continue into early next week. A disturbance forecast to pass south of the islands early next week could boost trade wind speeds.
