Chicago's Cook County is bracing for an extreme heat wave this weekend, with temperatures expected to soar into the 90s for several consecutive days. The National Weather Service (NWS) forecasts that the combination of heat and humidity will push the heat index above a dangerous 100 degrees Fahrenheit.
Extreme Heat Alert in Effect
An extreme heat alert will be in effect for Cook County from 10 a.m. Saturday until midnight on Tuesday, according to weather officials. This extended period of high temperatures poses a significant risk to public health, especially for vulnerable populations.
“First and foremost, I want to make sure every Chicagoan understands the danger of this moment and any moment when we have extreme heat,” said Mayor Brandon Johnson during a Friday morning press conference.
Prolonged Heat Wave Creates Higher Risk
Brett Borchardt, a meteorologist with the National Weather Service, warned that this first heat wave of the year could last until Tuesday. The extended duration of the heat, combined with high nighttime temperatures and the time elapsed since the last heat wave, could make it more deadly, as people are less prepared.
“The impacts of heat are cumulative,” Borchardt stated. “If you spend one day in the heat, no problem, but on the third and fourth day, that’s when it really starts to take a toll on our bodies, especially when we’re not able to cool off at night.”
Cooling Centers and Safety Tips
Approximately 11% of Chicago residents lack access to air conditioning. Dr. Olusimbo Ige, commissioner of the Chicago Department of Public Health, urged those without adequate cooling to visit cooling centers or, at a minimum, to cool their necks using cold cloths. She emphasized the importance of staying hydrated, avoiding strenuous activities during peak heat hours, and checking on elderly neighbors or family members.
- Stay hydrated by drinking plenty of water.
- Avoid strenuous activities during the hottest part of the day.
- Seek out air-conditioned spaces, such as cooling centers or libraries.
- Check on elderly neighbors and family members.
- Never leave children or pets in parked cars.
