An excessive heat warning is in effect until 8 p.m. Wednesday for southern Illinois.
According to the National Weather Service, dangerously hot conditions with heat index values of 110 to 115 are expected Monday afternoon, 105 to 110 on Tuesday afternoon, and around 105 degrees Wednesday afternoon.
Extreme heat and humidity will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities.
Overnight lows will only fall into the mid 70s to around 80, providing little relief.
During extreme heat, officials advised to to 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, OSHA recommends scheduling frequent rest breaks in shaded or air-conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location.
Call 911 for any heat stroke-related emergencies.
