Tornado touches down in Sienna Plantation

Harvey started as a Category 4 hurricane when it made landfall near Corpus Christi around 10 p.m. Friday, and slowed to a still devastating Category 2 by early Saturday morning.

The storm quickly grew Thursday from a tropical depression into a Category 1 hurricane, and then developed into a Category 2 storm early Friday. By Friday afternoon, it became a Category 3 storm before strengthening to a Category 4. Harvey is the first Category 4 hurricane to hit the Texas coast since Hurricane Carla in 1961.

With its strong winds and heavy rain, Harvey left plenty of damage in its path.

A confirmed tornado ripped through the neighborhood of Sienna Plantation early Friday morning. At least 50 homes were damaged, Fort Bend County Judge Robert Herbert said. 

There were no reports of injuries.
