High surf warning extended for portions of Garden Isle

The National Weather Service has extended the high surf warning in effect for north- and west-facing shores of Kaua‘i and Ni‘ihau until 6 p.m. Monday. Additionally, State Parks has closed the Kalalau Trail until further notice because of rising stream levels.

The NWS reports dangerously large breaking waves of up to 50 feet along north-facing shores, with surf of up to 35 feet along west-facing coastlines. Because of the hazardous conditions, Ocean Safety Bureau officials advise no swimming at north- and west-facing shores during the warning period.

An extra large northwest swell is expected to bring extremely dangerous giant size surf. Coastal water overwash could occur across many low lying roadways along northern and western facing shorelines, especially during periods of high tide.

The National Weather Service says strong breaking waves and powerful currents are forecast, with ocean water surging and sweeping across beaches, periodically overtopping vulnerable coastal roadways, causing localized beach erosion. Be prepared for road closures.

Wave runup could also impact coastal properties and infrastructure, especially during morning high tide.

Powerful longshore and rip currents will be present, according to the weather office. Beachgoers are urged to stay out of the water and away from shorelines in these areas.

Surges and strong currents inside exposed harbors could cause damage to boats because of the jostling of boats and floating docks. Waves breaking in channel entrances might make navigating these channels dangerous. Postpone entering or leaving channels affected by the high surf until the surf subsides.
