“Heat related illnesses increase significantly during extreme heat events. Overexposure can cause heat cramps and heat exhaustion to develop and, without intervention, can lead to heat stroke,” describes the NWS.
This watch is in effect until Thursday at 8 p.m.
During heat waves, consider the following tips from the NWS
- Stay hydrated: Remember to drink plenty of fluids.
- Seek shelter: Stay indoors in an air-conditioned room to keep cool.
- Stay out of the sun, and check up on relatives and neighbors.
- Child and pet safety: Never leave young children and pets unattended in hot vehicles – car interiors can reach lethal temperatures in a matter of minutes.
- Take extra precautions outdoors: If you work or spend time outside, be sure to take additional safety measures.
- Consider the timing: When possible reschedule strenuous activities to early morning or evening.
- Be alert to warning signs: Educate yourself about the signs and symptoms of heat exhaustion and heat stroke.
- Dress comfortably: Wear lightweight and loose-fitting clothing.
For a safer outdoor work environment, follow the Occupational Safety and Health Administration (OSHA)’s guidance by scheduling regular rest breaks in shaded or air-conditioned places. If anyone shows signs of heat illness, promptly move them to a cool, shaded area. In an emergency, call 911.
