July 5, 2022

The City of Chicago’s Office of Emergency Management and Communications will monitor conditions citywide and escalate plans as needed for extreme heat conditions and any threat of severe weather

The City of Chicago’s Office of Emergency Management and Communications (OEMC) is monitoring weather conditions citywide and will work with City of Chicago departments and agencies to provide resources for residents to find relief from extreme heat forecasted for tomorrow and throughout the summer.

The National Weather Service in Chicago has issued a Heat Advisory in effect for Tuesday, July 5 at noon through 8 p.m. with expected peak afternoon heat index values between 105 to 109 degrees. Hot temperatures and high humidity may cause heat illnesses to occur.

Residents should contact 3-1-1 if they are in need of assistance. It’s also important to check on relatives, neighbors, seniors and our vulnerable populations when temperatures climb to extreme levels. If you are unable to make contact, you can request a wellbeing check by downloading the CHI311 app, visiting, or calling 3-1-1. If there is a medical emergency due to a heat related illness, call 9-1-1.

During hours of operation, residents can also find relief in one of the City’s more than 75 Chicago Public Library locations and more than 31 Chicago Park District fieldhouses as well as 176 splash.

OEMC will continue to monitor conditions with the National Weather Service (NWS) in Chicago. To receive the latest updates on heat advisories and weather emergencies residents can register for the City’s emergency alert notifications at

If conditions warrant, an extreme heat warning will be issued by the National Weather Service (NWS) when the heat index is expected to exceed 105°-110°F for at least two consecutive days. Once issued, the city’s emergency response plan is activated.

Heat-related Illness
Heat exhaustion is a milder form of heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement of fluids. Heatstroke is more serious and occurs when the body starts to lose its ability to regulate itself. The telltale signs of heatstroke are:
• An extremely high body temperature, such as 103 degrees or above
• Dizziness and nausea
• A throbbing headache and a pulse that is rapid and strong
• Skin that is red, hot and dry

If you see someone suffering from heatstroke, call 9-1-1 immediately and then try to move the person into a cool place and cool the person with water.

Tips to Beat the Heat
• Stay hydrated – drink lots of water, AVOID alcohol, caffeine, sodas.
• Stay inside, if you don’t have air conditioning, keep shades drawn and blinds closed, but windows slightly open.
• Keep electric lights off or turned down.
• Minimize use of your oven and stove.
• Wear loose, light, cotton clothing.
• Take cool baths and showers.
• Don’t leave anyone (including pets) in a parked car, even for a few minutes.
• It’s important to check on family, friends, neighbors and especially our seniors…staying connected is key.

Weather and Public Safety
OEMC will monitor events through a collaboration with public safety partners. OEMC advises Chicagoans to be aware of weather conditions and to follow instructions and heed all warnings from public safety officials. We encourage residents to check the weather before heading out. For the most up-to-date weather information, please tune into local media or download a weather app.
