Multiple cars swept away in LA River during Tuesday storm

Los Angeles city fire crews Tuesday morning were reporting a total of three vehicles in the Los Angeles River at the Washington Bridge near downtown Los Angeles. 

Two of the vehicles are stacked atop each other in the water, but a third has been washed downstream, where L.A. County fire crews are staging by the river in the Compton area.

According to a Public Information Officer, it's believed only one of the cars swept into the river had anyone inside. That person was able to escape safely.

The Los Angeles Fire Department was attempting to recover one vehicle that rolled into the Los Angeles River shortly before 6 a.m. 

Crews found the car at 7:30 a.m., against a column or abutment in the river, with water rising due to the storm rolling through. LAFD says that once conditions allow, crews will attempt to recover the vehicle. The driver of that vehicle has not been located.

By 8 a.m., some mountain and foothill areas had already received as much as 7 inches of rain, while coastal and valley areas had received between 1 and 3 inches, according to the National Weather Service.

Traffic signals were knocked out of service on Pacific Coast Highway from Coastline to Cross Creek in the Malibu area, making already treacherous driving conditions even more dangerous.
