EXTREME HEAT WARNING
Neighbors can expect dangerously hot conditions with possible heat index values around 105°
June 29, 2026
Dear Neighbor,
The National Weather Service (NWS) is forecasting several days of dangerous heat and humidity across the Chicago area this week and has issued an extreme heat warning.
WHEN: The Watch will be in effect beginning Monday, June 29 at 12 p.m. through Wednesday, July 1 at 10 p.m.
IMPACT: Heat related illnesses increase significantly during extreme heat and high humidity events. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check on relatives and neighbors.
The Office of Emergency Management and Communications (OEMC) is closely monitoring conditions alongside the National Weather Service and will continue coordinating with City departments to support neighbors, particularly our most vulnerable populations, if conditions worsen.


The combination of heat and humidity may make it feel at or above 100°F for several days in a row, so now is the time to prepare.

Check on Your Neighbors
The magnitude of anticipated heat, combined with oppressive warmth at night will lead to hazardous conditions, particularly for the elderly, young children, neighbors experiencing homelessness, and people with pre-existing or underlying health conditions.
Please take a moment to check on family members, neighbors, and friends. You can request a well-being check by calling 3-1-1, visiting 311.chicago.gov, or using the CHI311 app. If someone is experiencing a heat-related medical emergency, call 9-1-1 immediately.
Neighbors in need of shelter can also contact 3-1-1 for shelter placement. During periods of extreme heat, the City's Homeless Outreach and Prevention teams proactively conduct well-being checks, provide transportation to cooling centers and shelters, distribute water and other essential supplies, and connect unsheltered neighbors with available resources.

ComED
ComEd offers a variety of energy efficiency tips to help manage costs during extreme heat. Visit ComEd.com/HomeSavings for more information.
Public safety is paramount, and ComEd encourages customers to take the following precautions:
If you encounter a downed power line, stay away and report it immediately to ComEd at 1-800-EDISON1 (1-800-334-7661). Spanish-speaking customers should call 1-800-95-LUCES (1-800-955-8237). Never assume a power line is safe.
If you experience a power outage, report it to ComEd by texting OUT to 26633 (COMED), calling 1-800-EDISON1, or using ComEd's Outage Tracker.
In the event of an outage, do not approach ComEd crews working to restore power to ask about restoration times. Crews may be working on live electrical equipment, and the perimeter of the work zone may be hazardous.
Additional Reminders
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.
Under Chicago's Cooling Ordinance, certain residential buildings must provide air conditioning in apartments or maintain an air-conditioned common cooling area when the heat index exceeds 80°F.
If you plan to visit one of Chicago's beaches, only swim when lifeguards are on duty and check water conditions before heading out.
I've attached additional heat safety graphics with additional resources and important information. Please take a few minutes to review them and share with friends, family, and neighbors who may benefit.
As always, our office is here to help connect you with City resources. Let's continue looking out for one another during this week's extreme heat.
Stay cool, stay hydrated, and stay safe!
Yours in Service,
Alderwoman Angela Clay
