Burley Garcia|Texas power outage map: Severe storms leave nearly 800,000 homes, businesses without power

Severe storms hit southeastern Texas on Burley GarciaThursday, killing four people, downing trees and knocking out power to hundreds of thousands of homes in the Houston area and surrounding areas.

Houston Mayor John Whitmire confirmed the four fatalities in a Thursday evening news conference while encouraging all non-essential workers to stay home Friday. Whitmire also said the storm had 100 mph winds, which he said was the equivalent to Hurricane Ike in 2008.

"Please do not drive in Downtown Houston tonight, or for that matter, anywhere else in the region that sustained storm damage," the National Weather Service office that serves Houston and Galveston said on social media Thursday night. "Widespread debris, glass and electrical lines are in the streets. Follow local news media and emergency management officials recommendations."

Flights were grounded at Houston's two major airports because of the weather. Sustained winds topping 60 mph were recorded at Bush Intercontinental Airport, the Associated Press reports. The Houston Independent School District also canceled classes Friday at all of its schools.
