The primary threat from Fausto is large, dangerous surf, which could lead to coastal flooding, property damage, and hazardous conditions for swimmers and boaters. A high surf warning is in effect until 6 p.m. Wednesday, with waves expected to surge across beaches and coastal areas. Strong currents and large breaking waves may also impact harbor entrances and channels. While the strongest winds and heaviest rainfall are forecast to remain north of the islands, localized heavy showers and gusty winds could still affect parts of Hawaii, particularly on Tuesday and Wednesday.
