High Surf Warning in Effect for East Side
Alerts (as of 1:00 a.m.)
A Tropical Storm Warning is posted for Hawaii County.
A High Surf Warning is also posted for the east facing shores of the Big Island from 6 a.m. Friday to 6 a.m. Sunday. Surf is forecast to build to 12 to 20 foot faces Friday with higher sets at the best exposures. Waves this big can cause coastal flooding and lead to dangerous ocean conditions. Powerful currents are also a concern and large breaking waves can impact harbor entrances and channels.

Darby swell is expected to peak Friday at warning levels before slowly fading through the weekend. Still highly dependent on Darby’s progress as it approaches the state. At this point, Estelle and Frank are not likely to send significant swell to the Hawaiian Islands.
Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
