The NWS Phoenix AZ issued an extreme heat watch at 11:36 p.m. on Sunday valid from Wednesday 10 a.m. until Thursday 8 p.m. The watch is for Imperial County Southwest, Imperial County West and Imperial Valley.

The NWS informs, "Dangerously hot conditions. Afternoon temperatures of 109 to 115 degrees possible. Localized Major Heat Risk."

"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," explains 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: 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: Do not leave young children and pets unattended in vehicles when car interiors can reach lethal temperatures in a matter of minutes.
• Exercise caution outdoors: If you work or spend time outside, take additional safety measures.
• Time your activities wisely: If possible, reschedule strenuous activities to early morning or evening when the heat is less intense.
• Recognize warning signs: Familiarize yourself with symptoms of heat exhaustion and heat stroke.
• Stay cool with clothing: Select lightweight and loose-fitting outfits for enhanced comfort.

To minimize risks during outdoor work, the Occupational Safety and Health Administration (OSHA) advises incorporating frequent rest breaks in shaded or air-conditioned areas. If someone experiences heat-related symptoms, promptly relocate them to a cool and shaded spot. In case of an emergency, dial 911.
