A sudden thunderstorm brought powerful winds and intense rain to San Diego's East County Tuesday afternoon.

“All of a sudden you couldn’t even see the parking lot because the wind and the rain were pure white just coming down," said Debbie Barrett, who was at a Rancho San Diego shopping center when the storm hit. "Everything in the front was flying around. Trees were falling."

Fallen trees crushed cars, damaged buildings and blocked roads.

“Everything was just going sideways. I saw some of the dead branches starting to blow off and the next thing I know, the whole tree is going over," Dan Barber said.

NBC 7 meteorologist Dagmar Midcap said the sideways winds were caused by a microburst.

"A microburst happens when the rain cools the atmosphere and the weight of the storm begins to collapse. That air has to go somewhere when it hits the ground. Those wind bursts go sideways,” Midcap said.
