At least one person is dead and another is missing amid massive waves fueled by a West Coast storm that hit the California coast on Monday.

The death was reported in Watsonville on Monterey Bay, where a man was found trapped under debris at Sunset State Beach. According to the Santa Cruz County Sheriff’s Office, a large wave trapped him there. He was pronounced dead at a hospital.

About 13 miles south at Marina State Beach, authorities believe high surf also likely pulled a man into the Pacific Ocean around 11:30 a.m. Monday. Strong currents and high waves forced searchers to abandon their search for him and the man remained missing on Monday evening.

A high surf warning remained in effect until at least 6 p.m. Tuesday. The National Weather Service in Monterey warned of breaking waves up to 35 feet high and life-threatening conditions in coastal areas.

On Monday, waves also caused the collapse of a pier at Santa Cruz Wharf, about 70 miles south of San Francisco. Two people were rescued and another swam to safety when part of the structure fell into the sea. Nobody was seriously injured.

“As the latest in a series of storms hit the West Coast, a large westerly swell brought the threat of waves as high as 30 or 35 feet breaking on beaches,” said Weather.com meteorologist Sara Tonks. “A buoy north of Santa Cruz near Port Arena, California, reported wind gusts of up to 36 mph and wave heights of up to 25 feet early Monday morning.”

The wharf was under construction after falling into disrepair over time and being hit by storms last year. According to an update posted to the wharf’s Facebook page Monday evening, it will remain closed until further notice. Adjacent beaches remained closed due to debris littering the area.

According to the National Weather Service Bay Area office, there were reports of ocean rescues even before Monday’s collapse.

“Stay away from the water, you are endangering your life and those of the people who will then have to try to rescue you,” the agency wrote in a social media post.

Due to the high surf, an evacuation order was issued for parts of the area.

Coastal roads in Santa Cruz were closed following the partial collapse of the pier, city officials said.

Gov. Gavin Newsom has been informed and the state’s Office of Emergency Services is coordinating with local officials, the governor’s office said.

The region will see a brief respite from active weather on Wednesday for Christmas and the first day of Hanukkah, but later in the week the next storm will arrive on the coast in a parade, Tonks said.

The Santa Cruz Wharf collapse occurred Monday about a year after the Seacliff State Beach Pier just off the coast was damaged beyond repair by a severe winter storm.
