 W-D-E-L. On the CBS News Weekend Roundup. I'm Allison Keys. That deadly heat wave that's been baking the nation isn't over yet, and it's especially awful in places devastated by Hurricane Beryl, such as Texas. Some half a million in the Houston area won't have electricity until next week, and angry residents are waiting in long lines for food and water. CBS's Janet Chamleon is there.
