Much of the South and Midwest are dealing with record-breaking temperatures again this week. The National Weather Service has issued heat warnings for 12 states, including Texas.
The temperatures in many areas have reached 100 degrees or above, and in some places it feels like 120.
In Texas, the humans aren't the only victims of the heat. High water temperatures have been killing the state's fish in large numbers.
"It can get to the point where the fish actually do not have enough oxygen in the water and they will suffer," explained Larry Hodge, of the Texas Parks and Wildlife Department.
Topeka, Kan., saw a scorching 112 degrees. Forecasters expect temperatures there to hit the triple digits for at least the next five days.
In Oklahoma, the National Weather Service has issued heat warnings that extend until Saturday.
The heat and humidity are putting many at risk for heat-related illness.
