Heavy rain caused by the remnants of Tropical Storm Mario resulted in at least one death, as well as flooding and mudslides Thursday in San Bernardino County.
In Barstow, a car was swept off the road at about 7:15 p.m. The driver, Brandon Padilla Aguilera, was rescued by the Barstow Fire Department. His 2-year-old son, Xavier Padilla Aguilera, was carried away by the rushing water and died. In a Facebook post Friday, the city said authorities searched for the boy for 20 hours before finding the body.
"We extend our deepest condolences to those affected by this tragedy," the city wrote. It added an acknowledgement of first responders and volunteers "who worked around the clock in challenging conditions."
South of Barstow, in the San Bernardino Mountains, debris swept through the Potato Canyon, Oak Glen and Forest Falls communities — which lie north of Beaumont and south of Big Bear Lake — starting at about 4 p.m. Thursday, according to the San Bernardino County Fire Department. Multiple flash flood warnings were issued by the National Weather Service, as rainfall rates reached 1.5 inches per hour. More than 2 inches of rain fell across parts of the area.
Crews still were working to get into the communities to do damage assessments as of Friday morning. Highway 38 was blocked at Valley of the Falls Drive.
The threat of heavy rainfall is largely gone, though we could see light moisture early next week.
The damage is a reminder of how powerful and fast-moving storms and their aftermath can be.
