(Des Moines) The National Weather Service issued a Heat Advisory for the western half of Iowa from 1:00 p.m. to 8:00 p.m. today. Forecasters expect heat index values up to 105 degrees, and high humidity may cause heat illness. The best advice is to stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. The forecast high for Monday is 94 degrees, and Tuesday’s high is 93.
A Heat Advisory is issued within 12 hours of the onset of hazardous heat conditions. The general rule of thumb for this advisory is when the maximum heat index temperature is expected to be 100 degrees or higher for at least two days, and nighttime air temperatures will not drop below 75 degrees; however, these criteria vary across the country, especially for areas not used to dangerous heat conditions.
Take precautions to avoid heat illness. If you don’t, you may become seriously ill or even die.
