Detroit, Michigan – An extreme heat wave is blanketing Southeast Michigan, with temperatures in the upper 90s and heat indices reaching 105° in Metro Detroit through 8 p.m. Tuesday, prompting an Extreme Heat Warning for Wayne, Oakland, and Macomb counties.
According to the National Weather Service in Detroit, the rest of Southeast Michigan—including Ann Arbor, Flint, and Port Huron—remains under a Heat Advisory through Tuesday evening. Nighttime lows are offering little relief, raising concerns for heat-related illnesses, especially among vulnerable populations.
Cities including Detroit, Pontiac, and Warren are seeing the most intense impacts, with minimal cooling overnight and infrastructure stress on air conditioning and utilities. Schools and summer camps may adjust outdoor activities, and residents are urged to avoid prolonged sun exposure.
Preparedness actions include drinking water regularly, avoiding strenuous activity in peak heat hours, and checking on elderly neighbors or those without cooling. Authorities strongly advise against leaving children or pets in vehicles.
