Looking Ahead

ARTICLE CONTINUES BELOW AD

Breezy trade winds are expected to continue through the week and could become locally windy on the Big Island this weekend. Clouds and showers continue to focus over the windward coasts and slopes, though the trades will be strong enough to carry some showers to leeward areas. Heavy showers and thunderstorms will be possible on the Big Island later Saturday through Monday as a moist and unstable tropical air mass moves over the southern end of the state.
