(KRON) -- With storm-powered waves forecast to reach 35 feet this weekend, city officials announced they will close the wharf and all Santa Cruz beaches until the giant swell eases. The beaches and wharf closure will begin on Friday, November 13, at 10 p.m., and continue through Sunday, November 15 , at 5 a.m. The National Weather Service issued a High Surf Warning for "waves potentially reaching 25 to 35 feet along portions of the coast," City of Santa Cruz officials wrote. "Large waves can arrive unexpectedly, sweep people off their feet, and create life-threatening conditions even for those standing well away from the water."

On Friday, double overhead wave sets were already pounding the coast, and gusty winds created messy conditions for surfers. XL waves are forecast on Saturday, with 15-foot sets at Pleasure Point in Santa Cruz and 30-foot sets at Mavericks near Half Moon Bay, Surfline reported. Along Monterey County's beaches, officials warned of waves as large as 50 feet.

"Waves of 25 to 35 feet are expected, with occasional waves reaching 40 to 50 feet in certain areas. Over the past several years, our community has experienced heartbreaking tragedies in which individuals have lost their lives under similar ocean conditions. What began as a simple visit to enjoy the beauty of our coast ended in tragedy for families," the sheriff's office wrote. Officials said, if you see someone swept into the ocean, call 911 immediately. Do not enter the water to attempt a rescue, because doing so could place additional lives at risk, MCSO said. ...read more read less
