Memorial Day Weekend Weather Forecast
Alerts (as of 1:00 a.m.)
Special Weather Statement: Coastal flooding is anticipated the Memorial Day weekend along all shores of the Hawaiian Islands due to record level spring (king) tides. Impacts include beach flooding, standing water on roadways and low-lying areas near the coast. A large summer south swell is also expected to exacerbate the problem leading to additional beach run up, flooding and erosion.
High Surf Advisory: South facing shores through 6 a.m. Sunday.
