Looking Ahead

Moderate trade winds are expected into next week. Tropical moisture from former tropical cyclone Nora and an old front will spread across the island chain through the weekend, resulting in a wetter weather focused mainly over windward and mauka areas. This moisture will pass west of the islands by Monday with drier conditions expected during the first part of next week.
