For the second time this month, high surf was slowing traffic in Kaaawa.

Kamehameha Highway was being contraflowed Saturday due to high-surf erosion on the shoulder lane, the Department of Transportation said.

DOT urges drivers to exercise caution and to be prepared for delays in the area.

A high-surf advisory remains in effect until 6 p.m. today for the north shores of Oahu, Molokai and Maui, according to the National Weather Service.

Also under the advisory are the north and west shores of Kauai and Niihau. Surf is expected to reach 15 to 20 feet today.

Surf along the west shores of Oahu and Molokai was expected to rise to 10 to 15 feet today.

On Feb. 11, high surf washed over the highway and damaged some of the asphalt and guardrail in Kaaawa. The DOT closed the northbound lane of Kamehameha Highway near Kaaawa Valley Road and Kanenelu Beach.

Crews removed the damaged asphalt and guardrail, filled the area with controlled low-strength material, installed a new guardrail and repaved the roadway.

The temporary fix allowed two-way traffic to resume while the state worked on a long-term solution.
