Maui and Molokai could see “extremely dangerous surf and overwash” as an extra large northwest swell arrives in the islands, the National Weather Service said Tuesday.
North- and west-facing shores of Molokai and north-facing shores of Maui are under a high surf warning through 6 a.m. Thursday with the potential for “dangerous large breaking waves” of 25 to 35 feet along north shores and 20 to 25 feet along west shores.
The weather service warned of very strong breaking waves and powerful currents that could make navigating channels dangerous. It advised the public to stay away from affected shorelines and impacted channels.
Hookipa, Baldwin and Kuau Bay beach parks reopened on Tuesday after being closed Sunday due to high surf and flooding. No damage was reported.
On Tuesday, the state Department of Health issued a brown water advisory from Waihee to Maliko and from Honolua Bay to Kahekili Beach Park following recent high surf.
The department is advising the public to stay out of coastal waters that appear brown due to possible runoff containing chemicals, pathogens and debris.
