A tidal surge swallowed streets in Newport Beach on Monday as king tides battered Southern California. The Guardian and the New York Post reported knee-deep floodwater in an upscale Orange County neighborhood. Coastal communities across the state were preparing for days of flooding amid potentially record-breaking tides.

The National Weather Service warned that significant coastal flooding was expected in San Diego and Orange counties. Residents of coastal towns were urged to avoid beaches during high tides and keep farther from the ocean than usual. Water levels began rising Monday as the tide cycle peaked.

King tides are the highest astronomical tides of the year and often preview future sea-level risk. City crews sandbagged low spots while residents moved cars. The pages did not list a death toll tied to the Newport Beach flooding.
