The U.S. National Tsunami Warning Center issued a tsunami warning for California’s northern coast late Tuesday after a distant seismic event generated long-distance waves. Officials said the first waves were expected to reach Crescent City at about 11:50 p.m. local time. Early Wednesday, monitoring stations confirmed tsunami waves of roughly 1.6 feet above normal tide levels at Arena Cove and about 3.6 feet at Crescent City. Authorities advised residents and mariners to stay clear of beaches and harbors until the advisory is lifted, warning that additional, potentially stronger surges could follow.
