King tides inundate streets and flood homes and businesses along both US coasts

HUNTINGTON BEACH, Calif, Oct 29, (AP): King tides have inundated parts of both US coasts, flooding streets and sending seawater into homes and businesses in beach communities in California, Florida and the Carolinas. The tides began with the full moon earlier this week and could cause flooding in some areas into the weekend, forecasters said.

King tides are caused by the gravitational pull and alignments of the Earth, moon, and sun. They can occur several times a year and last several days. This week's king tides have been exacerbated by additional factors, forecasters said Wednesday. In Florida, strong high pressure to the north and low pressure over the Caribbean were causing increased swells, Chris Fisher, a National Weather Service meteorologist in Miami, said.

Along the California coast, the ongoing super El Niño has warmed the ocean, leading to an increased volume of seawater. Another factor was the occurrence of Kelvin waves, a series of pulses of warm water that lift the sea level, said Roger Gass, a meteorologist with the weather service's Bay Area forecast office in Monterey. This week's king tides, like their name, have definitely been noticeable. Residents didn't need a beach to see the ocean.

The ocean came to them. In Southern California, Stacey Frederick snapped photos and videos of people walking in knee-deep water and paddleboarding on the Pacific Coast Highway outside a coffee shop where she works as rising tides pushed water ashore. Officials shut down traffic on a flooded portion of the four-lane highway, which winds from Orange County up through California. King tides aren’t new, yet this was unusual, Frederick said.

"It floods a little bit, but never to this point,” said Frederick, 38, who has lived in Huntington Beach for five years. Record high tides were set this week in Santa Barbara, San Pedro, San Diego and nearby La Jolla, according to the weather service. In Sunset Beach, the water washed over the three layers of sandbags that Lorraine Friedman, 75, had stacked inside her garage and on the small patio outside her studio apartment.

She has lived in the seaside community for nearly three decades and her apartment has flooded only once before, some 20 years ago. "This is the second day I’ve been flooded - two days - and tomorrow I’ll get flooded again,” she said Wednesday. In the northern part of the state, minor flooding was expected through Saturday in low-lying areas along shorelines and tidal waterways during peak high tides, the weather service said.
