HOUSTON -

Residents in northwest Houston are cleaning up after a powerful storm knocked out at least one roof and several windows.

The storm rolled in Saturday afternoon and hit the Spring Branch area particularly hard.

Brian Rios was sitting home alone in the 2300 block of Jacqueline Drive when the winds lifted up the metal poles to his carport and sent them crashing into his roof.

"It just sounded like a big boom, like two cars were colliding," Rios said.

His father's vintage car, which was sitting in the driveway, was also damaged.

A few blocks away, Jose Hernandez captured cellphone video of what appears to be a funnel cloud in the sky.

"All of a sudden the winds started coming real fast and it sounded like a train or something," Hernandez said.

The storm shattered windows at the La Catalina Apartments on Johanna Drive. It also knocked down an entire wall of cinder blocks at a storage facility on the same street.

"The first thing that came to my mind was to hit the floor because everything was flying," said Maria Mungia, who lives in apartment complex near the storage facility.

As of 10 p.m. Saturday, Center Point Energy reported there were still 1,500 residences across the Houston area without power.
