Looking Ahead

ARTICLE CONTINUES BELOW AD

Increasing trades will keep showers focused over windward and mauka areas during the next several days. The southern portions of the aloha state will see more shower activity as a weak surface trough passes just to the south. The trough will strengthen just west of Kauai heading into the weekend. This will result in a return to southeasterly winds and an increased threat of unsettled weather over the western islands.
