Continued high surf meant more activity for lifeguards on Oahu’s north and west shores as a massive northwest swell worked its way across the state Sunday.

Lifeguards recorded 17 rescues, 41 assists and 4,155 preventive actions as adventurous surfers braved monstrous surf and visitors and locals alike flocked to the beach to take in the spectacle of 30-foot waves.

Despite the volatile conditions, only one rescue on Oahu resulted in a hospitalization. An 11-year-old girl was treated by lifeguards and paramedics after swallowing water at Nanakuli Beach Park, Emergency Services spokeswoman Shayne Enright said.

She was transported to an area hospital in unspecified condition.

A high-surf warning remains in effect for north- and west-facing shores of Oahu, Kauai, Molokai and Niihau and north-facing shores of Maui through 6 p.m. today. In addition, a high-surf advisory for west shores of Hawaii island and a small-craft advisory for coastal waters within 40 nautical miles are also in effect through the same period.

Forecasters warn that large breaking waves will cause hazardous conditions, including life-threatening rip currents, in the surf zone. Localized coastal flooding and beach erosion may also occur, particularly during high tide this morning.

The National Weather Service predicts generally light winds with local land and sea breezes through today with passing showers for the windward areas of Maui and Hawaii island. A weak front will move southeast across the islands tonight through Tuesday, bringing an increase in showers.
