Looking Ahead
Light to moderate trades have returned and will hold through tonight, then gradually increase as Hurricane Olivia begins to approach the state Tuesday. The latest forecast from the Central Pacific Hurricane Center (CPHC) has Olivia moving through the eastern end of the state late Tuesday into Wednesday as a tropical storm, then passing south of Oahu and Kauai Wednesday into Thursday. Expected impacts for each island through this period can be found in the local hurricane statements and the latest CPHC advisories. A wet pattern with gusty trades will likely hold Thursday through Friday as Olivia continues westward and away from the state. A drying trend appears likely from east to west Friday through the upcoming weekend.
