Dangerous heat period signaled for Northern, Central Illinois

High temperatures and humidity expected during watch

Large portion of Illinois under heat watch
The Extreme Heat Watch covers a large portion of Illinois, including major cities like Chicago, Peoria, Springfield, and their surrounding areas. Residents throughout Northern and Central Illinois should closely monitor weather forecasts and heed safety advice.
Stay safe with these helpful precautions
* **Stay Hydrated:** Drink plenty of water throughout the day, even if you don't feel thirsty. Avoid sugary drinks and alcohol, which can dehydrate you. * **Seek Air Conditioning:** Spend time in air-conditioned environments, such as shopping malls, libraries, or cooling centers. Check with your local municipality for a list of cooling centers near you. * **Limit Outdoor Activities:** Reduce strenuous activities during the hottest parts of the day (typically between 10 AM and 4 PM). If you must be outside, take frequent breaks in the shade. * **Wear Appropriate Clothing:** Wear light-colored, loose-fitting clothing to help your body stay cool. A wide-brimmed hat can also provide protection from the sun. * **Check on Vulnerable Individuals:** Pay attention to elderly neighbors, individuals with chronic illnesses, and young children. These groups are particularly susceptible to heat-related illnesses. * **Never Leave Children or Pets in Cars:** Temperatures inside a vehicle can rise rapidly, even with the windows slightly open. This can be fatal. * **Know the Signs of Heat-Related Illnesses:** Be aware of the symptoms of heat exhaustion (dizziness, headache, nausea, weakness) and heatstroke (high body temperature, confusion, seizures). If you suspect someone is experiencing heatstroke, call 911 immediately.
