 Centerpoint rolled out a new map to check the progress of restoration after people were using a Whataburger fast food app to track outages near them. The utility said it had brought in about 12,000 additional workers from outside Houston since landfall to expedite power restoration. Worsening the situation is the scorching heat which has descended on the region. The heat index hit 100 degrees in Houston yesterday and residents were rushing to distribution centers for food, water and ice.
