Hilary has triggered deadly flooding, heavy rains, and powerful gusts across parts of the southwest and Mexico, transforming streets into raging rivers and forcing some residents to flee, and leaving others in need of rescue, even after weakening to a post-tropical cyclone.
More rain is expected to fall throughout Monday and Tuesday as officials clean up the aftermath. After hitting Southern California on Sunday as a tropical storm – the state’s first since 1997.
Hilary headed into Nevada as its first-ever recorded tropical storm and was moving over central parts of the state early Monday, about 390 miles north of San Diego, packing sustained winds of 35 mph with higher gusts, the National Hurricane Center said. As Hilary moves across the southwest, the storm has brought power outages, life-threatening flooding, and calls for residents to evacuate or shelter in place.
Live updates: Hilary brings major flood risk to California
The storm broke rainfall records across Southern California: Palm Springs got nearly a year’s worth of rain with 4.3 inches in 24 hours, one of its rainiest days ever. Death Valley nearly set a record with 1.68 inches, and the Furnace Creek area, which usually gets about two-tenths of an inch in August, got 0.63 inches.
And the storm is the rainiest tropical storm system in Nevada’s history, nearly doubling the state’s 116-year-old all-time record, according to preliminary data from NOAA’s Weather Prediction Center. Hilary has released 8.7 inches of rain on Lee Canyon, Nevada, smashing the previous record of 4.36 inches in 1906.
More rain is expected to cause dangerous flash, urban and arroyo flooding in some places, including landslides, mudslides and debris flows. Localized flooding is expected into Tuesday morning across northern portions of the Intermountain West.
In Palm Springs, a section of Interstate 10 is shut down while road crews clear away mud left behind by floodwaters from Tropical Storm Hilary, but other routes in and out of the desert oasis near Joshua Tree National Park are open.
In addition, many freeway off-ramps are limited because of mud, and CalTrans crews are working to clear those in an effort to ease accessibility.
Emergency telephone service, which had been down since midmorning, has been restored, the police department said, but an outage continues to affect other areas of the Coachella Valley.
“With what we’re expecting, it may overwhelm us.”
Here’s the latest:
• Flood watches are in effect for more than 16 million people from Southern California to northern Idaho. Places that normally don’t see flash flooding “will flood,” the National Weather Service said. “Lives and property are in great danger through Monday.”
• Strong and gusty winds are due to persist Monday across portions of the Western US, particularly in and near areas of higher terrain. Coastal tropical storm warnings have been discontinued.
• More than 48,000 customers are without power across California, PowerOutage.us reports. About 18,000 customers remain without power in Los Angeles, and 43 crews are working throughput the city to get their power back on, Marty Adams, general manager and chief engineer at the Los Angeles Department of Water and Power, said Monday. He said a total of about 41,000 customers were without power at one point, and the city has restored power to about 22,000 customers.
• People in parts of Southern California should not travel unless they are fleeing an area under flooding or under an evacuation order, the National Weather Service has warned.
• Flooding, mudslides and downed trees and wires are widely reported across Southern California. At least nine people were rescued Sunday in a San Diego riverbed, San Diego Fire-Rescue said, with water rescues also reported in Ventura County and Palm Springs.
• In Mexico, where the storm first landed, power has been restored to 80% of customers in the three states affected by Hilary, according to the national power company. “379,850 users have been affected, and electricity supply has been restored to 302,134, equivalent to 80%,” said the Federal Electricity Commission in a statement Monday.
To the west, Los Angeles and Ventura counties saw “considerable damage” Sunday night amid reports of dangerous flash flooding, and rock and mudslides, the National Weather Service said, adding up to half an inch of rain could fall per hour.
Cars were stuck in floodwaters in the Spanish Hills area, the National Weather Service reported.
Crowley urged residents to take precautions on the roads.
“A relatively small amount of water can sweep a vehicle away,” she said.
And as Hilary triggered flood warnings across Los Angeles, a magnitude 5.1 earthquake on Sunday afternoon shook the area and other parts of Southern California, the United States Geological Survey said.
In Los Angeles, the worst of the storm was over as of Monday morning, according to officials. All weather warnings in the city were canceled. “We are past the brunt of the impact,” said National Weather Service meteorologist Ariel Cohen.
First day of school is a wash for some students
Schools in San Diego and Los Angeles are set to reopen Tuesday after closing Monday in anticipation of the storm. Officials canceled classes for the more than 121,000 students in the San Diego Unified School District.
The Los Angeles Unified School District, the second-largest in the nation, also shut down Monday. The district spans about 700 square miles, meaning the impact of the storm varied for its students.
Schools in the Los Angeles district will reopen on Tuesday, according to superintendent Alberto Carvalho.
“Our teams have been scouring our schools, and so far, conditions are pretty good,” Carvalho said. A couple dozen schools have lost phone and internet service, and one school has been impacted by a minor mudslide.
“It would have been reckless for us to make a different decision,” Carvalho said of the decision to close schools Monday.
“Los Angeles was tested but we came through it and we came through it with minimal impacts, considering what we endured,” said Los Angeles City Council President Paul Krekorian.
The Nye County School District in Nevada also canceled classes Monday, with plans to reopen Tuesday.
Cars stranded in roads deluged with mud and water
Once a hurricane, Hilary weakened as it made landfall Sunday in Mexico – where at least one person died – then crossed into the Golden State. The storm’s center was roughly 10 miles southeast of downtown Los Angeles around 8 p.m. local time Sunday, moving north with weakened 45-mph winds, according to the hurricane center.
The Los Angeles Fire Department fielded more than 4,000 emergency calls on Sunday and responded to about 1,800 incidents, Chief Kristin Crowley said in a news conference on Monday. The calls included a request for help for five cars stranded in a flooded intersection of Sun Valley. One person was safely rescued and no one was injured in the Sun Valley incident, Crowley said.
Flood water has affected an underground power vault, leading to an outage for about 6,000 customers in the Beverly Grove area, with other outages reported in Hollywood, Hyde Park and Brentwood. The vast majority of city power customers remain unaffected by the storm, according to Los Angeles officials.
As the storm barreled through, covering roadways with debris and water, roads were blocked across Southern California by Sunday night. A section of Interstate 8 in Imperial County, east of San Diego, was closed Sunday after boulders came loose from an adjoining slope and fell into the road.
In San Bernardino County, a stretch of State Route 127 covered in floodwaters was closed, while a section of Interstate 15 was shuttered in Barstow because of downed power lines after a lightning strike, authorities said.
Crews across the region Sunday evening rescued people caught in the storm, including at least nine in a riverbed area in San Diego. “Crews are still looking for more people who may need help. #riverrescue,” San Diego Fire-Rescue said.
And Ventura County firefighters searched the Santa Clara River for people trapped in the waters on Sunday night, videos show.
The storm led to other disruptions across Southern California, with many parks, beaches and other locations closed as officials called on residents to stay indoors.
And Hilary is continuing to cause damage as it moves into Nevada. In Mt. Charleston, Nevada, the storm brought significant flooding on Monday morning, washing out the roadways. Residents are sheltering in place, the power is shut off, and the Nevada National Guard is on its way to assist, according to a Facebook post from Clark County.
West of Las Vegas, rushing water is flowing like a river down Echo Road, leaving vehicles stranded from Mary Jane Trailheads and Trail Canyon, according to the U.S. Forest Service. Emergency crews are evaluating and ask for people to stay out of the area, the service said.
Record rainfall in Southern California
California had been preparing for difficult conditions, positioning first responders across Southern California to brace for water rescues in flood-prone areas like wildfire burn scars and deserts amid fears areas unaccustomed to rain could suddenly receive a year’s worth or more, triggering flash floods and landslides.
Rainfall totals have been significant:
Daily and monthly rainfall records were broken Sunday, with 1.53 inches falling in downtown Los Angeles, 1.56 inches in Long Beach and 2.95 inches in Palmdale, according to the weather service.
In Cathedral City, a desert community roughly a 110-mile drive east of Los Angeles, at least a dozen people were being rescued Monday afternoon from a senior boarding care facility after mud trapped them inside, city spokesperson Ryan Hunt said.
All of the people being rescued are “doing OK,” Hunt said. No other information was immediately available.
Santa Clarita, about 30 miles north of Los Angeles, experienced steady rain for about 10 hours, with the storm dropping well over four inches of rain on the valley. Parts of Sand Canyon Road could be seen falling into rushing water.

As the storm continues to affect the West, officials with Oregon’s emergency management are bracing for possible flooding across portions of the state.
“We have reports of minor flooding currently and communities using sandbags to mitigate the impacts, but there have been no requests for state support at this point,” Crabb went on.
According to Crabb, the office is working with county and tribal partners.
Portions of Oregon are under a flood watch through Tuesday afternoon, according to the National Weather Service.
“The remnants of Hurricane Hilary will bring periods of moderate to heavy rain to portions of northeastern Oregon through Tuesday,” the weather service said in a forecast message.
