Heat Advisory for counties in orange


The National Weather Service in Des Moines has issued a Heat Advisory, which is in effect from 1 PM Friday to 7 PM CDT Sunday.

* TEMPERATURE…High temperatures will range from 95 to 99 degrees. With dewpoints in the low 70s, heat index values will range from 100 to 105 degrees throughout this time period.

* IMPACTS…Lack of overnight relief from the heat will lead to additional stress. Strong daytime winds will increase the risk of dehydration. The prolonged nature of this event will compound and amplify heat-related impacts.


A Heat Advisory means that a period of hot temperatures is expected. The combination of hot temperatures and high humidity will combine to create a situation in which heat illnesses are possible. Drink plenty of fluids, stay in an air-conditioned
room, stay out of the sun, and check up on relatives and neighbors. Do not wait until you are thirsty to drink. Avoid drinking alcoholic and caffeinated beverages as they dehydrate you.

Never leave infants, children or pets in a parked car, even for a minute.

Take extra precautions, if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water.

To reduce risk during outdoor work, the occupational safety and health administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency, call 9 1 1.
