The National Weather Service in Chicago has issued an Excessive Heat Warning from Monday noon to Tuesday 10 pm due to dangerously hot conditions with heat index values up to around 105 degrees Monday and up to around 110 degrees possible Tuesday.  Dangerously hot conditions with heat index values between 103 and 107 Monday and around 110 Tuesday expected. 

An Air Quality Alert is in effect until midnight Monday.  The Illinois Environmental Protection Agency has determined that an Air Pollution Action Day will be declared for the greater Chicago Metropolitan Area.  An Air Pollution Action Day is declared when weather conditions are such that widespread ozone and or particulate levels are expected to be at or above the Unhealthy for Sensitive Groups category of the Air Quality Index for multiple days.  Active children and adults, especially people with pulmonary or respiratory disease such as asthma, should limit prolonged outdoor activity. Area residents are urged to reduce pollution levels. Air quality forecasts, current air quality, and tips on how you can reduce your emissions can be found at www.airnow.gov .

As extreme weather can be hazardous and unpredictable, OEMC and City departments are reminding residents and visitors of safety tips and the resources available in event of a storm or heat emergency to help alleviate the impact.

Public safety is the top priority of the City of Chicago and OEMC will work closely with the National Weather Service in Chicago to monitor conditions. Should emergencies, severe storms or extreme heat arise, OEMC will coordinate the City’s response by working with departments citywide to assist residents and vulnerable populations.

The city’s emergency response plan is operational when an extreme heat warning is issued by the National Weather Service (NWS) when the heat index is expected to exceed 105°-110°F for at least two consecutive days.

To receive the latest updates on heat advisories and weather emergencies, residents can register  for the City’s emergency alert notifications at NotifyChicago.org, check OEMC’s social media pages, tune to local media or download the Chicago OEMC App.

CPS is reminding all school leaders and families that our school leaders and teachers are eager and ready to welcome back students to classes August 26, for the first day of School Year 2025. All CPS classrooms are equipped with air conditioning, and District staff will be working with schools to fix any air conditioning issues that may occur and to follow the District’s policies and procedures and move students as needed to a cooler space.

CPS has canceled all outdoor athletic contests for Monday, August 26 and Tuesday, August 27. In addition, all outdoor practices will either be moved indoors or canceled on these days.

The District is reminding school leaders to keep classrooms comfortable; draw shades to keep out sunlight, close doors in rooms with window air conditioners, and turn off overhead lights, computers, monitors, and appliances when not required for instruction. CPS also advised families to dress children in light, loose-fitting clothes, and to please send them to school with full water bottles. 

All outdoor athletic contests will be canceled for Monday, August 26 and Tuesday, August 27. In addition, all outdoor practices will either be moved indoors or canceled on these days.

The Department of Family and Support Services (DFSS) will now operate the cooling centers at Community Service Centers Monday through Thursday. They will operate normal hours except for Garfield Service Center which will be open for extended cooling on Monday and Tuesday. 

Due to the Excessive Heat Warning, the DFSS Senior Services team, working with OEMC, is sending a robocall out to seniors on Monday and is monitoring well-being checks. 

The City of Chicago’s cooling areas located at the City's six community service centers operated by the Department of Family and Support Services will be open from 9 a.m. to 5 p.m. Note: the Garfield Service Center at 10 South Kedzie from 9 a.m. to 5 p.m. for cooling and 24/7 for those needing shelter placement. 

Also from Monday, August 26 through Friday, August 30, all six DFSS Senior Centers will be open from 8:30 am to 4:30 pm (Renaissance Court from 10 am to 5 pm).

(For additional information, visit 311.Chicago.gov or call 3-1-1.)

Chicago Park District facilities, Chicago Public Libraries, City Colleges of Chicago and Police Department District stations are also available for relief from the heat and humidity. Chicago Police Department district stations are available 24 hours for relief from the heat and to be connected with shelter.

Chicago Public Library is providing evening and extended hours as we respond to the extreme heat and is striving to keep as many locations open as possible to help offer much-needed relief from hot temperatures.

For locations and hours, visit Cooling Centers - Map | City of Chicago | Data Portal. Residents can also call 3-1-1 for the nearest location and hours. Information about Chicago Park District beaches, pools, water playgrounds, and water spray features is available here. Note: Only the Chicago Park District facilities listed on the data portal provide access to air conditioning, as some facilities are not air-conditioned.

Homeless outreach teams will operate citywide. On Monday, August 26th through Thursday, August 29th, DFSS and delegate agency street outreach teams will be operating across the city during the day. Three outreach delegate agencies will be operating in the evening in select locations. 

When the temperatures climb to extreme levels, it is important to check on relatives, neighbors, seniors, and our vulnerable population. If you are unable to make contact, you can request a well-being check by downloading the CHI311 app, visiting 311.chicago.gov, or calling 3-1-1. If there is a medical emergency due to a heat related illness, call 9-1-1.

The Department of Family and Support Services will conduct robocalls to seniors in their network to notify them of the extreme heat and provide information to stay cool. 

When the temperatures climb to extreme levels, we encourage everyone to monitor themselves and others for the telltale signs of heat-related illness. Extreme sweating, intense thirst, nausea, fatigue or weakness, and dizziness or confusion can all be indicators of heat exhaustion or heat stroke. Some people are at greater risk than others: infants and young children, people 65 years of age or older, people who are overweight, individuals who work outdoors and those who are physically ill, especially with heart disease or high blood pressure, or who take certain medications, such as for depression, insomnia, or poor circulation. If there is a medical emergency due to a heat related illness, call 9-1-1.

 

The Chicago Department of Buildings (DOB) advises property owners and building managers to check their electrical and cooling equipment now to make sure it is in working order before the temperatures really start to rise.
