Detroit, Michigan – Residents across southeast Michigan have a limited window to prepare before a prolonged stretch of dangerous heat settles into the region Tuesday afternoon. Daytime temperatures climbing into the mid-90s to near 100 degrees, combined with oppressive humidity, are expected to push heat index values above 105 degrees through Thursday evening. The lack of overnight cooling will add to the risk, with lows only falling into the low and mid-70s.
According to the National Weather Service in Detroit/Pontiac, an Extreme Heat Watch remains in effect from Tuesday afternoon through Thursday evening for much of southeast Michigan, including Detroit, Ann Arbor, Flint, Pontiac, Warren, Port Huron, Howell, Monroe, Adrian, Midland, Bay City, Saginaw, Lapeer, Caro, Sandusky, Bad Axe and surrounding communities.
The extended heat wave is expected to increase the risk of heat-related illnesses, especially for older adults, young children, outdoor workers and anyone without reliable air conditioning. Urban areas such as Detroit, Warren and Pontiac may experience even warmer overnight temperatures because buildings and pavement retain heat after sunset, limiting recovery from daytime conditions.
Residents are encouraged to stay hydrated, avoid strenuous outdoor activity during the hottest part of the afternoon, and spend time in air-conditioned buildings whenever possible. Never leave children or pets inside parked vehicles, where temperatures can become fatal within minutes. Those without home cooling should check with local emergency management officials for available cooling centers.
The heat watch remains in effect through Thursday evening, and additional heat advisories or warnings may be issued as confidence in the intensity of the event increases. Monitor updates from the National Weather Service and local officials as conditions evolve.
