A tornado was confirmed in a Los Angeles County city Thursday. Where is Pico Rivera?
An EF0 tornado was confirmed in Pico Rivera early Thursday morning amid an ongoing storm drenching Southern California. The National Weather Service Los Angeles confirmed the tornado between 3 a.m. and 4 a.m. Thursday, according to a post on X. The tornado had a wind speed of 85 miles per hour and was one mile in length and 80 yards in width, according to preliminary details from the NWS Los Angeles. It lasted two minutes, and caused 'exterior damage to homes and cars, multiple snapped trees.' NWS Los Angeles said Wednesday that a weak tornado was possible in the storm impacting the state. 'We don't want to rule out the chance for a brief, weak tornado, although the overall rain is the largest hazard with this storm,' said Rose Schoenfeld, meteorologist with the NWS Los Angeles in a webinar Wednesday. Pico Rivera is city in Los Angeles County that's about 13 miles southeast of downtown Los Angeles. The city is home to over 62,000 people, according to the 2020 U.S. Census Bureau. The Enhanced Fujita Scale is used to assign a tornado a rating based on estimated wind speeds and related damage, according to the NWS office in Oklahoma. Tornados can receive an EF rating of zero to five. It's important to note that the EF scale is a set of wind estimates, not measurements. A tornado with an EF0 rating had a three-second gust of 65-85 miles per hour at the point of damage, according to the Storm Prediction Center.

Where and when rain is forecast to hit wildfire burn scar areas around Southern California
Forecasters released a breakdown Tuesday of where and when heavy rainfall this week is expected to hit areas of Southern California left burn-scarred by recent wildfires, raising the risk of potentially dangerous debris flows in those parts of the region. Debris flows and mudslides are most common during a period of intense rain following wildfires, the rain potentially destabilizing the terrain that was scorched barren and carrying land, mud and even sometimes larger objects like boulders, according to the National Weather Service. Areas of Los Angeles County left burn-scarred by the deadly Palisades and Eaton fires last month are among the areas where forecasters are warning of possible flooding and debris flows triggered by rainfall this week. Those burn scars, along with parts of the region burned by the Franklin Fire in the Malibu area and the Bridge Fire in the Angeles National Forest last year, are the areas at greatest risk of seeing debris flows, forecasters say. Here is the breakdown National Weather Service Los Angeles has given for where and when is expected to hit burn scar areas. Lake Fire: The area left burned by the 38,000-acre wildfire that broke out in a northern area of Santa Barbara County last July is one of the parts of the region expected to see heavy rainfall this week. A flood watch is in effect between 10 a.m. Thursday until 12 a.m. Friday. Palisades, Eaton, Franklin and Bridge Fires: All these wildfires burned through areas of Los Angeles County between last summer through January this year, with the Bridge Fire burning in neighboring San Bernardino County. A flood watch is in effect for all these burn scar areas from 1 p.m. Thursday until 4 a.m. Friday. "Given the elevated chances for significant debris flows, consisting of raging torrents of rockslides and mudslides that can be damaging and even deadly, now is the time to start getting prepared for these potentially dangerous conditions," National Weather Service Los Angeles Meteorologist Ariel Cohen said Tuesday, predicting a 50 to 70 percent chance of such "significant" debris flows. Still expecting strong storm for #SoCal Wed-Fri - Significant rain likely all areas - 10-20% chance of thunderstorms Thu/Thu night - Widespread roadway flooding likely - Moderate to high risk of mud/debris flows near recent burn scars - Snow levels 6000 ft or higher #CAwx — NWS Los Angeles (@NWSLosAngeles) February 11, 2025 Emergency preparations have been underway, including the placement of more than 7,500 feet of concrete barriers and 6,500 sandbags in the Palisades Fire area alone. Meanwhile, state officials have been carrying out cleanup efforts, which include clearing out debris that heavy rain can carry and taking other measures to lower the risk of mudslides and debris flows, over the last month. A flash flood watch is also in effect for other parts of Southern California including Orange County and Riverside County, where emergency officials met with firefighters and law enforcement in Lake Elsinore to discuss storm preparations, including those bracing for the possibility of mud and debris flow in recent burn areas, according to the county's Emergency Management Department.

Heavy rain sends mud onto PCH, highway shut down from Malibu to Santa Monica
Heavy overnight rain sent mud flowing onto the Pacific Coast Highway, leading to a full shutdown of the highway between Malibu and Santa Monica Friday, authorities said. Forecasters had issued a flood advisory for that area of the coastline Thursday night, with the National Weather Service Los Angeles warning of possible "mud flows and shallow debris flows" in areas left burn-scarred by the Palisades Fire. On Friday, Caltrans officials said a slide occurred in an area of the Pacific Coast Highway just north of Big Rock Drive in Malibu. Lanes in both directions on the PCH are closed between Carbon Beach Terrace in Malibu and Chautauqua Boulevard in the Santa Monica area, the transportation agency said just before 9 a.m. It's a roughly 11-mile stretch of the highway, which was just beginning to reopen after being fully closed for weeks due to the Palisades Fire and ongoing cleanup efforts. Bulldozers had to remove about 10 truckloads of debris, Caltrans officials said, saying there was more debris drying out on the shoulder of the highway before being removed Friday morning. The agency's geotechnical team is going to closure area Friday to determine when the highway can reopen. 🚧PCH UPDATE🚧 A slide occurred overnight on PCH, just north of Big Rock Dr. Caltrans crews removed about 10 truckloads of debris. There is more on the shoulder drying out before removal. Our Geotechnical team will survey the closure area today to decide if & when to reopen. #PCH — Caltrans District 7 (@CaltransDist7) February 7, 2025 Video from overnight shows heavy rain pouring down in the Pacific Palisades and nearby areas, mud dislodging from boulders along the PCH and spilling onto the roadway. With rain in the forecast this week, fears have arisen over mudslides and debris flows being triggered by the precipitation, particularly in areas where wildfires have left the terrain scorched barren.
