A new west-northwest swell prompted high surf advisories for north and west facing shores on Oahu, Kauai County and Molokai and for north shores of Maui.

The westerly component of the swell should wrap and bring some below-advisory level waves to some south shore beaches, National Weather Service forecasters said.

The surf of 18 to 24 feet is expected on north and west shores Friday.

The surf is expected to bring strong breaking waves, shore break and rip currents that could make swimming difficult and dangerous on north and west shores.

The advisory is in effect until 6 a.m. Saturday.

Some town spots on Oahu’s south shore could see surf rising to 3 to 7 feet Friday as waves wrap around west shores,

However, a cold front moving over the islands wil bring breezy south to southwest winds and rain to Oahu and Maui on Friday. 

Winds of 10 to 15 mph Friday, could gust to 30 mph on south shores and should shift to the north winds in the afternoon and evening after the front passes.

The swell will gradually subside from Saturday into early next week. Another small to moderate west-northwest swell is expected to arrive on Tuesday.
