HONOLULU (HawaiiNewsNow) - Surf from a second south swell is expected to start rolling in sometime on Friday.
With the waves forecast to be as big or bigger than the current swell, the National Weather Service has extended the High Surf Advisory for all south-facing shores until 6 p.m. Saturday.
It takes waves of at least eight feet to trigger that advisory.
Inexperienced surfers and swimmers should stay out of the big waves.
There could be dangerous rip currents along southern shorelines and beach erosion is also a possibility.
Tune in to Hawaii News Now tonight beginning at 5 p.m. with Guy Hagi for the latest on the waves and the weather.
