Heat-induced illness can occur amid such high temperatures.

To help prevent heat illness caused by high temperatures and humidity, the NWS recommends taking the following precautions and steps:

  • 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 911.
