 As Texans clean up from the destructive hurricane barrel, in Houston, the heat index expected to soar to the triple digits again today. Even though I open up all the windows, you get the breeze, your house is still hot. Oh, wow. Dangerously hot for nearly 2 million Texans still without power. The storm already blamed for at least nine deaths in the U.S. With power outages entering a third day, some residents are prepared to leave to find relief.
