I tried to catch it late flight last night, and it was canceled. Airport was crazy. Ended up driving to Vegas to escape. Everybody is not prepared and it's going to be a shit show trying to leave Southern California. If you stay there, be prepared to be without power and Internet… pic.twitter.com/cFMUZgzuot

Palm Springs and the Coachella Valley, a dry, desert area that rarely sees rain at all, began trending internationally on X late Sunday night as witnesses and residents shared footage on social media of cars floating, roads that looked like bodies of water, and debris filling the streets.

Palm Springs and others parts of Southern California faced the threat of flash flooding along with landslides and mudslides today after storm Hilary unleashed record-breaking downpours overnight.

The National Weather Service has warned of "life-threatening and locally catastrophic flooding" across the Southwestern U.S. into Monday evening.

"Post-Tropical Hilary is expected to produce additional rainfall amounts of 2 to 4 inches, with isolated storm total amounts to 12 inches, across portions of Southern California and Southern Nevada through today," the NWS said. "Continued flash and urban flooding, locally catastrophic, is expected."
