Full Notification

The National Weather Service has extended an Extreme Heat Warning for the City of St. Louis until Wednesday, 7/30/2025, at 7:00 p.m.

Dangerously hot conditions with heat index values up to 113 are expected and can quickly cause heat stress or heat stroke if precautions are not taken. The very young, the elderly, those without air conditioning, and those participating in strenuous outdoor activities will be the most susceptible. Also, car interiors can reach lethal temperatures in a matter of minutes. 

Drink plenty of fluids, stay in an air-conditioned room, avoid the sun, and check on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances. 

Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early

morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight, loose-fitting clothing whenever possible. 

To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1.
