NWS suggests anyone who works or will spend time outside on Monday to take extra precautions or possibly reschedule strenuous activities to the evening. 

“Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible,” NWS said. “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.”
