A severe storm with hurricane-force winds and embedded tornadoes swept through Houston on Thursday evening, causing widespread damage and significant power outages. Winds gusting between 80 to 117 mph blew out windows in high-rise buildings, downed trees, and toppled transmission towers. The storm left over 1 million customers without power, with Harris County being particularly affected. At least four people have been confirmed dead, according to Houston Mayor John Whitmire, and officials have urged residents to stay off the roads due to the dangerous conditions.
