Alerts (as of 1:00 a.m.)
Special Weather Statement: Coastal flooding is likely through Memorial Day 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 fading but will exacerbate the problem leading to additional beach run up, flooding and erosion. The flooding is likely to be worst during the evening high tide.
