OSKALOOSA — An excessive heat warning went into effect on Sunday for much of the southern half of Iowa and remains in effect through 9pm on Wednesday (8/23).

The National Weather Service indicates that heat index values over the next few days will peak between 105 and 115. Extreme heat and humidity will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities. The long duration of the heat can be particularly hard on the very young, the elderly and those with medical conditions.

The NWS says you should take precautions, particularly those vulnerable to the heat. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances. 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 lightweight and loose fitting clothing when possible. 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.
