Hilary updates: Over 1 foot of rain hits San Bernardino as LA avoids catastrophe

All tropical storm warnings have been canceled across Southern California as the remnants of Hilary, which no longer meet the threshold of a tropical cyclone, track north.

Once a Category 4 hurricane, Hilary tore through Southern California with historic rainfall on Sunday, flooding roads and knocking out power.

Hilary's record-breaking stats

Hilary, the first tropical storm to move into Southern California since 1997, marked the first time ever that tropical storm watches were issued in the region.

Sunday set a new record for the wettest August day ever in Palm Springs, San Diego and downtown Los Angeles.

Hilary's highest rain total was in Upper Mission Creek in San Bernardino County, where 13 inches of rainfall was recorded.

Tropical storm warnings canceled across Southern California

All tropical storm warnings have been canceled across Southern California as the remnants of Hilary, which no longer meet the threshold of a tropical cyclone, track north, according to Ariel Cohen, meteorologist in charge at the National Weather Service Los Angeles.

Residual mudslides and rockslides are still a threat in California from the weekend rain.

The moisture from Hilary is now moving through the Rockies. On Monday, the flooding threat will be from the Sierra Nevada mountains into the northern Rockies in Idaho and eastern Oregon.

LA schools expected to reopen on Tuesday

Los Angeles "avoided a potentially catastrophic set of conditions" from Hilary, LAUSD Superintendent Alberto Carvalho said Monday.

Carvalho defended the decision to close LA's public schools on Monday citing reasons including that many students walk to school and many employees live outside of LA.

"It would have been reckless for us to make a different decision" on Sunday, he said.

Schools appear to be in good condition, he said, noting that about 24 schools don't have phone or internet access and one elementary school that serves students with disabilities appears to have been impacted by a mudslide.

Carvalho said students should expect to resume their regular school day on Tuesday.

LA residents should stay vigilant for mudslides, downed wires

No deaths or major injuries have been reported in Los Angeles from Tropical Storm Hilary, LA Mayor Karen Bass said at a news conference Monday.

While LA Fire Department Chief Kristin Crowley said no major damage has been confirmed, the mayor warned that "damage can occur in the hours and days after a storm hits, so Angelenos should continue to stay vigilant."

Mudslides and downed wires are also still a threat, Crowley cautioned, adding that residents should continue to avoid flooded roads.

She said rescuers on Sunday night responded to a flooded intersection where five cars were stranded. No one was hurt, she said.

The mayor added that no injuries were reported from Sunday's earthquake, which was unrelated to Hilary.

Over 1 foot of rain hits San Bernardino County

Rainfall totals from Hilary have reached 13.5 inches in San Bernardino County, California, and 11.7 inches in the mountains of Riverside County, California.

Los Angeles County recorded over 7 inches of rain while Palm Springs saw more than 3 inches, which broke the desert city's all-time daily summer rain record.

Bristlecone, Nevada, northwest of Las Vegas, recorded 8.4 inches of rain, including 6 inches in just 24 hours, breaking the rainfall record for a tropical cyclone or remnant in the state.

Hilary also brought fierce winds. In California, gusts reached a whopping 87 mph in the San Gabriel Mountains and 84 mph at Big Black Mountain.

Flash flood warnings continue amid record rain

Flash flood warnings remained in effect on Monday in Los Angeles, Death Valley and some areas of southwest Nevada, after heavy rain fell overnight throughout the region.

Hilary weakened overnight into a post-tropical cyclone and was expected to dissipate in the high mountains of the Sierra Nevada.

Copious amounts of rain fell overnight, including the 10.5 inches that soaked Raywood Flat, California, a rocky area within the San Bernardino National Forest.

About 6.15 inches fell in Los Angeles. Palmdale, a city north of the Los Angeles, had its highest all-time daily rainfall with 3.57 inches.

Palm Springs got 2.82 inches, marking the city’s highest daily rainfall for summer and for August.

San Diego had 1.81 inches, its highest-ever daily August rainfall.

And Bristlecone, Nevada, near Las Vegas, picked up more than 6 inches, mostly within 24 hours. That rainfall broke the record for a tropical cyclone or remnant traveling through Nevada. It approached the 24-hour rain record for the state of 7.78 inches, which was set in 2004.

Hilary winds slow down, but flash flood warnings remain

As of 11 p.m. ET/8 p.m. PT, Hilary remains a tropical storm with maximum sustained winds now down to 45 mph. The center of Hilary is located about 105 miles northwest of San Diego. It is moving at 28 mph.

Widespread flash flood warnings remain in effect across Southern California as areas of heavy rain continue to sweep through the region. The flash flood warnings in Los Angeles and Ventura Counties have been extended until 3 a.m. PT Monday. Flash flooding is ongoing across the region. There are also warnings in many desert areas, including Death Valley.

The widespread heavy rain in Southern California will begin to ease up soon, first in the southeastern part of the state. After 10 p.m. PT Sunday, there is a notable improvement regionwide, with the worst of the heavy rain over and the rain becoming less intense. There is lingering rain overnight in some areas but not as heavy as earlier.

Even though the rain ends, there could still be residual impacts, like landslides or rockslides.
