The bi-state region will be under a heat advisory beginning mid-morning on Monday. Temperatures are to be in the 90s to 100s, with heat indexes in the 110s.
The affected regions are in south central, southwest, and west central Illinois. Portions of northeastern Missouri, including the St. Louis metro area, are also impacted.
The heat advisory will go into effect beginning at 11 a.m. Monday, June 13. It will remain in effect until 8 p.m. on Wednesday, June 15.
The National Weather Service in St. Louis is providing some important preparedness actions:
- Drink plenty of fluids. Dehydration and heat stroke are often due to not keeping hydrated in high temperature and high humidity situations, leading to hospitalization.
- Stay in an air-conditioned room.
- Stay out of the sun whenever necessary.
- Young children and pets should never be left unattended in vehicles under any circumstances.
- Take extra precautions if working or spending time outside.
- Limit strenuous activities to the early morning or late evening hours.
- Know the signs and symptoms of dehydration, heat exhaustion, and heat stroke.
- Wear lightweight and loose-fitting clothing whenever possible.
- OSHA regulations recommend regular breaks in shaded or air-conditioned environments.
- Anyone overcome by heat should move to a cool and shaded location, while someone calls 911.
