Newport Beach Flood Prep: 22-Inch Surge Forecast

Newport Beach residents face immediate changes to their daily routines as the city mobilizes against a predicted surge in ocean levels. Local authorities declared a local emergency more than a week before the highest tides are expected to arrive, aiming to protect streets, homes, and businesses from potential inundation.

City staff are currently working across the area to reinforce beach berms and install protective equipment. The municipality is distributing free sandbags to residents and urging them to check low-lying areas around their properties. These actions come in response to a National Weather Service warning that predicts significant coastal flooding in Orange County and San Diego through Thursday.

The NWS expects tides to reach as high as eight feet in parts of the region, which could close roads and submerge critical infrastructure. In the San Diego office, officials advised the public to avoid beaches during high tide periods. They instructed people to stay further back from the ocean than usual, noting that waves will travel much farther up the sand than expected. Residents should also stay off rock walls and jetties to avoid being caught by breaking waves.

Newport Beach city manager Seimone Jurjis explained that ocean water levels are already running 15 to 22 inches higher than normal. This deviation is driven by the combination of El Niño conditions and a Kelvin wave. Jurjis noted that a rise of a foot and a half can determine whether water stays below a seawall or spills into garages and living spaces.

The current situation adds stress to a region already dealing with extreme weather this month. Recent events included flooding that overwhelmed city streets and large waves that damaged beachside homes. The remnants of Tropical Storm Rachel also passed through California, destroying a boardwalk and forcing evacuations in some areas. As a historic El Niño continues to unfold in the Pacific, the state anticipates severe storms will persist through the winter.

The NWS forecast indicates that minor to moderate coastal flooding is possible from San Luis Obispo County to Los Angeles County. While the most severe impacts are expected in the south, the wider stretch of the coast will see elevated water levels. The city’s early activation of its emergency protocol allows for a structured response before the peak of the tidal surge arrives.
