Hurricane Marie-Related Rain Pelts SoCal; Flooding Reported

LOS ANGELES, CA — Hurricane Marie-related rainfall pelted parts of the Southland Sunday, flooding some coastal areas and creating dangerous surf and rip currents.

Flooding was reported at parking lots in Seal Beach and Zuma Beach, and was "flowing into homes and streets" in Long Beach, according to the National Weather Service.

A flood advisory for west central Los Angeles County, including the Franklin and Palisades burn scars, expired at 1 p.m. Sunday, but another flood advisory, this one for eastern Los Angeles County including the Summit and Bridge burn scars, was in effect until 7:45 p.m., with Arroyo and small stream flooding expected. Motorists were urged to turn around if they encounter flooded roads.

The NWS reported Sunday afternoon that rain totals across Los Angeles County were around 0.25 to 0.75 inches, with an additional 0.10 to 0.25 inches possible.

The Los Angeles County Department of Public Health issued an ocean water quality rain advisory for all LA County beaches until at least 2 p.m. Wednesday. Beach users were cautioned to avoid water contact for at least 72 hours after rainfall.

Officials had already urged inexperienced swimmers to stay out of the water due to the rip currents.

The NWS said it had high confidence that Marie would remain well offshore but will send a growing southerly swell and large waves toward the coast as the Labor Day weekend continued, particularly at south-facing beaches.

A high surf advisory and coastal flood advisory will be in effect until 11 p.m. Tuesday for portions of the Los Angeles County and Orange County coasts.

Large breaking waves of 6 to 10 feet for south and southwestern-facing beaches and 4 to 7 feet for west-facing beaches are expected, with strong and dangerous rip and longshore currents.

Forecasters also warned of minor coastal flooding from a combination of high surf and high astronomical tides along vulnerable south-facing shores, with Avalon, Long Beach's Alamitos Peninsula and Malibu among the areas of greatest concern.

"With huge crowds expected at the beaches for the Labor Day holiday, the emphasis for these statements is to alert the public to be extra careful in and near the ocean," according to the NWS.

High tides will also increase through early next week and are expected to exceed 7 feet by Monday. The combination of elevated tides and the south swell will create a moderate risk of coastal flooding in some areas.

Marie is forecast to track northwest over the next several days while remaining well off the California coast.

Forecasters cautioned that roads could become especially slick with any wetting rain because of oils that have accumulated during the dry summer months.

There is also a 5% to 15% chance of thunderstorms, mainly in the Los Angeles County mountains and urban areas. Any stalled or repeatedly developing storms could produce more than a quarter-inch of rain in an hour, according to the weather service.

Los Angeles Mayor Karen Bass said her office will continue coordinating with the Emergency Management Department, Los Angeles Fire Department, Los Angeles Police Department, Los Angeles County Public Works and other relevant city departments to ensure all personnel are ready to respond as needed.

Humidity will increase as Marie's moisture reaches the region, with increased cloud cover expected through the weekend. Overnight temperatures could remain in the 70s along southern coastal areas and coastal valleys where clouds persist.

Forecasters said unsettled weather could linger into early next week as moisture from the remnants of Marie interacts with an unusually active jet stream over the region.

When the storm moves on, the Southland is in store for another heat wave, with temperatures soaring into the 90s in many areas beginning Monday and peaking Tuesday through Thursday with triple-digit highs in the warmer areas, before declining to more-average levels next weekend.
