Urban heat island

Ameren Missouri has disconnected more than 100,000 households that were behind on their bills in the past year. Advocates say Missouri laws need to change to better protect people in extreme heat.

During the heat wave, Red Cross shelters for tornado victims will also serve as cooling shelters for people who were affected by the storm.

The powerful May tornado tore down thousands of trees. That could mean the neighborhoods with the most damage feel even hotter as summer approaches.
