U.S. West Coast on Alert Again as Massive Waves Return

A renewed coastal emergency is unfolding along the U.S. West Coast as powerful Pacific storms generate massive waves, dangerous surf, and hazardous coastal conditions, especially along California. Emergency agencies are increasing warnings as long-period swells combine with storms to heighten risks of flooding, erosion, and infrastructure damage. With holiday travel ongoing, officials urge vigilance, as coastal hazards can escalate quickly with little warning over the next 48–72 hours.
