Flash flooding has sparked an emergency declaration in San Diego after four inches of rain fell in six hours on Monday.
San Diego mayor Todd Gloria declared a state of emergency after homes were inundated and cars were overturned as torrential rain swept through southern California over a roughly six-hour period on Monday.
Flood waters swept away vehicles and caused cars to pile on top of each other, while several feet of water inundated the Mountain View, Shelltown and Southcrest neighbourhoods, as well as multiple highways.
Meanwhile, three inches of rain fell in National City, while San Diego International Airport was hit with two inches of rain – the fifth-highest single-day total for any time of year since the National Weather Service began tracking rainfall totals in 1850, the San Diego Union-Tribune reported.
The San Diego Fire Department performed over 20 emergency rescue operations along the San Diego and Tijuana rivers, with at least eight migrants rescued after they were endangered by the floodwaters of the Tijuana River Valley on the US side, authorities said.
