In the Cajon Pass early Monday, the driver of a SUV that was pulling a trailer drove through waist-deep, swift-moving water. Fortunately, all three people in the vehicle were rescued.
Video showed the vehicle was pinned to a tree as a rescue team responded.
"They were screaming for their lives," San Bernardino County firefighter Chris Prater said about the rescue. "It was by far the scariest moment they said they had ever been in."
"Last night's scene had every common denominator for a fatal incident," Prater added. "These three individuals who were rescued were extremely lucky to make it out of that situation alive."
On many freeways, cars have been hydroplaning and spinning out of control. Derek Hernandez says his car can still be driven, but it's leaking oil. The car was hydroplaning and lost control.
"I felt the car start to swerve around, and that's when the guy hit me and I completely swerved around," he said.
In Colton, runoff caused part of a side street in one neighborhood to collapse. The owner of a home nearby has been told to be prepared to evacuate.
Officials aren't exactly sure what caused it, but it appears to be rain-related.
