King Tides Flood Newport Beach Streets

Newport Beach experienced significant street flooding Monday morning as king tides sent the ocean surging into neighborhoods, inundating streets with knee-deep water and prompting warnings for drivers.

The affluent coastal community in Orange County saw normally busy streets transformed into waterways, with residents working to protect homes and businesses. Aerial footage captured people stacking sandbags along Edgewater Avenue and Washington Street on the Balboa Peninsula as floodwaters advanced.

Areas near 38th Street and River Avenue, close to Newport Island, were submerged under about a foot of water. One resident described the flooding as unprecedented for the area, noting that a tidal gauge recorded a record 8.3 feet at 9:18 a.m. on Monday.

City officials had been preparing for the high tides, with crews reinforcing sand berms, deploying pumps, and inspecting seawalls. Newport Beach City Manager Seimone Jurjis stated that emergency resources were prepared to address the dangerous conditions.

This event follows a previous local emergency declared on October 9, when powerful swells and elevated tides caused similar flooding on the Balboa Peninsula, stranding motorists and submerging vehicles. That earlier incident was exacerbated by Tropical Storm Rachel and a Kelvin wave.

Coastal flood warnings were issued by the National Weather Service for Orange and San Diego counties through Thursday afternoon, with potential impacts to homes, businesses, and infrastructure. Less severe advisories were also in place for Los Angeles, Ventura, Santa Barbara, and San Luis Obispo counties.

Other Southern California coastal cities have also faced recent flooding. Long Beach has experienced destructive coastal flooding, with waves impacting waterfront properties and boardwalks. The flooding has also disrupted transportation, with Metrolink suspending service between Laguna Niguel/Mission Viejo and Oceanside stations due to elevated tides.

Millions in emergency funding have been allocated to repair a large crack that developed beneath Pacific Coast Highway near Laguna Beach during earlier October high tides. Forecasters attribute the unusually high tides to warming ocean waters linked to an emerging El Niño pattern and Kelvin waves, which are pushing sea levels above predicted astronomical levels.

Further exceptionally high tides are anticipated around Thanksgiving and Christmas, potentially impacting coastal communities already affected by recent events. The National Weather Service advises residents to avoid flooded areas, including roadways, beaches, jetties, and seawalls.
