Seven-day forecasts of temperature, humidity, wind speed, and cloud cover from the National Weather Service serve as inputs for Cattle Heat Stress Forecast Maps. The prediction of animal stress is based on an equation that combines weather forecast data to estimate cattle heat stress response, and produces a map showing stress categories by color. The U.S. Department of Agriculture offers daily maps for the current day and forecasted out six additional days, and provides maps for six regions of the contiguous United States.

The site also offers information on recognizing heat stress in animals and options for taking action to minimize heat stress before and during an extreme heat event.
