Surf produced by these swells could potentially be damaging along exposed south and southeast shorelines beginning late Friday and Saturday, and persisting through the weekend in some areas.

RAINFALL

Heavy rainfall associated with Ana may reach the Big Island of Hawaii Friday afternoon. These rains could cause life-threatening flash floods and mud slides.
