Extreme Heat Warning Saturday 6/21 through Tuesday 6/24

The National Weather Service has issued an Extreme Heat Warning for the City of St. Louis beginning at noon on Saturday, June 21, through 9:00 p.m. on Tuesday, June 24.

Dangerously hot conditions with heat index values up to 108 are expected. Heat-related illnesses increase significantly during extreme heat and high humidity events.

Extremely high temperatures and humidity could 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.

Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to the early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose-fitting clothing when possible and drink plenty of water.

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 immediately.

Where`s baby? Look before you lock! Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes.
