Tropical Storm Hilary makes landfall in California after earthquakes

Tropical Storm Hilary made expected to make landfall in Southern California Sunday evening, hours after dozens of earthquakes struck the Ventura County area.

After making landfall in California, Hilary marked the first time a tropical storm has touched down in California since 1939.

The news comes hours after the state dealt with more than a dozen earthquakes in the Ojai area and after Hilary made landfall on Mexico's Baja California coast. The storm is feared to bring deadly flash flooding in the border city of Tijuana, Southern California and places as far north as Idaho that rarely get such heavy rain.

As of Sunday night the storm has dropped more than six inches of rain on parts of Los Angeles County and more than three inches of rain on parts of Ventura County over the last 48 hours.

In anticipation of the possible landfall, California Gov. Gavin Newsom's office declared a state of emergency for most of Southern California "to support faster recovery and response efforts." Los Angeles County launched an emergency page for residents looking to get countywide updates on the storm, as well as where to turn to for resources. 

Newsom said 7,500 personnel were activated in southern California, with close to 4,000 California Highway Patrol members, 2,000 Caltran workers and mutual aid across the region. Newsom warned residents to take seriously any alerts of flash floods, lighting and possibility of tornadoes.

President Joe Biden also issued a statement Sunday, saying that federal officials were providing assistance to the area, and urging people to listen to local officials' calls for caution during the storm.

"I continue to be briefed on our preparedness efforts, and the storm’s potential impact — including flooding," Biden's statement read. "My Administration stands ready to provide additional assistance as requested. I urge people to take this storm seriously, and listen to state and local officials."

National Weather Service meteorologist Lisa Phillips says Los Angeles is expected to experience the peak of the storm's rainfall until 9 p.m. Sunday. She said showers are expected through the night into Monday, with showers tapering off during the day.

Customers with both SoCal Edison and LADWP reported power outages across the region due to the heavy rain.

Thousands of residents in Southern California also were rattled Sunday by a preliminary magnitude 5.1 earthquake and several aftershocks centered in Ventura County.

More Weather Alerts

Los Angeles Fire Chief Kristin Crowley, the city's incident commander for the storm, said 1.5 to 3 inches of rain was forecast for the Los Angeles area, along with winds of 20 to 30 mph. 

The Antelope Valley and San Gabriel Mountain areas, outside Los Angeles city limits, were expected to get the brunt of the storm, with 3 to 7 inches of rain and stronger winds, Crowley said.

Flash flooding and coastal flooding and dangerous rip tides were also expected.

Coastal areas will also be dealing with high surf that could create some flooding concerns in beach communities. 

Forecasters said surf of 4 to 7 feet is possible at southeast- and south-facing beaches, along with strong rip currents -- with Catalina Island "most vulnerable" to the strong swells.

The storm is expected to remain in the region through Monday morning, likely clearing out by early afternoon, with scattered thunderstorms possible Tuesday.
