The heat index is an estimate of the “apparent temperature” based on the combined temperature in the shade as measured by an ordinary dry bulb thermometer and the relative humidity. Conditions in direct sunlight will usually be substantially hotter.

Heat indices this high can cause death. The body loses the ability to regulate its temperature by evaporating sweat, possibly causing severe illness such as heat stroke, which is life-threatening. If outside, curtail strenuous activity, stay hydrated, take breaks, and seek shade when possible. Do not leave children or pets in vehicles. Check on elderly and other vulnerable people, especially if they have no air conditioning.

NWS advises “Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up 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 and loose fitting clothing when 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.”
