Extreme Heat Warning Until TUE 9:00 PM CDT
Heat index values are expected to reach 105 to 110, with health officials warning of illness risks and possible strain on power systems.
The National Weather Service issued an Extreme Heat Warning effective from noon Monday through 9 PM CDT Tuesday, with heat index values expected to reach 107 degrees across the region.
Dangerously hot conditions with heat index values between 105 and 110 are expected, increasing the risk of heat-related illnesses like heat exhaustion and heat stroke during prolonged exposure.
Residents should stay in air-conditioned environments, drink plenty of fluids, and avoid direct sun exposure while checking on vulnerable relatives and neighbors during peak heat hours.
Across Milwaukee County, cooling centers remain open with many sites located along Milwaukee County Transit System routes; call 911 immediately if heat stroke symptoms appear.
Extreme heat conditions may persist through much of next week, potentially affecting the 4th of July weekend, while overnight temperatures are expected to remain unusually warm.
