Original post: A high surf warning for the west-facing shores of the Leeward Big Island is in effect as a swell increases across the region, according to forecasters with the National Weather Service.

The warning will remain in effect from 6 a.m. on Monday to 6 a.m. on Tuesday, Dec. 16.

A large west-northwest swell from about 290 to 300 degrees is expected to bring dangerously large waves to the area, with surf peaking late Monday afternoon before gradually decreasing on Tuesday.

Surf heights are forecast to reach up to 12 feet along the affected shores, creating hazardous conditions for beachgoers and boaters. Strong breaking waves and powerful currents are anticipated, particularly in channel entrances, where navigating could be dangerous.

Officials are advising residents and visitors to stay away from the shoreline and avoid entering channels during the high surf event. The high surf may also lead to road closures in coastal areas. Authorities recommend postponing channel crossings until conditions improve, urging everyone to exercise extreme caution.

Officials also urge residents and visitors to use caution and follow guidance from ocean safety authorities. As a general rule, authorities advised, if conditions appear unsafe, stay out of the water and only swim at beaches with towered lifeguards.
