LAS VEGAS (July 11, 2026) — Extreme heat can become dangerous in minutes. With temperatures expected to reach 111 degrees this weekend, the American Red Cross of Southern Nevada is urging residents to take steps now to stay safe and check on those most at risk.

An Extreme Heat Warning remains in effect for the Las Vegas Valley, with temperatures expected to reach 111 degrees Saturday and remain near 109 degrees Sunday. Prolonged exposure to extreme heat can quickly lead to dehydration, heat exhaustion or heat stroke, especially for people working or exercising outdoors and those without reliable air conditioning.

Extreme heat is the leading weather-related cause of death in the United States, claiming more lives each year than hurricanes, floods and tornadoes combined. Data from the Centers for Disease Control and Prevention show that heat has killed about 2,000 people a year since 2020. Heat-related deaths reached 2,415 in 2023 and 2,394 in 2024, the two highest annual totals on record.

“Heat-related illness can happen quickly, especially when people are active outside or do not have a cool place to get out of the heat,” said Rachel Flanigan, Executive Director of the American Red Cross Southern Nevada Chapter. “Drink water regularly, don’t wait until you’re thirsty, check on neighbors and loved ones who may be at greater risk, and know where your local cooling station is before you need it. These simple steps can help prevent heat-related emergencies and save lives.”

Stay Hydrated, Stay Cool, Stay Connected
The Red Cross recommends taking these steps when temperatures rise:

• Stay hydrated: Drink water regularly and do not wait until feeling thirsty. Avoid alcohol and limit drinks with too much caffeine, which can contribute to dehydration.
• Stay cool: Spend time in air-conditioned places when possible. Avoid strenuous outdoor activity during the hottest part of the day and take breaks in the shade or indoors.
• Dress for heat: Wear lightweight, loose-fitting, light-colored clothing. Use sunscreen with SPF 30 or higher and reapply as needed.
• Check on others: Stay in contact with older adults, people with medical conditions, neighbors without air conditioning and anyone who may need help staying cool.
• Use caution in vehicles: Never leave children, pets or anyone with limited mobility in a parked vehicle, even briefly. Temperatures inside a vehicle can rise quickly, even when the windows are cracked.

Know the Signs of Heat Illness
Heat cramps, heat exhaustion and heat stroke can develop when the body cannot cool itself fast enough. Warning signs can include muscle cramps, heavy sweating, weakness, dizziness, nausea, headache, fainting or confusion.

• Heat cramps can cause muscle pain or spasms, often in the legs or abdomen. Move to a cooler place, rest and drink water or a sports drink.
• Heat exhaustion can include heavy sweating, weakness, nausea, dizziness, headache or fainting. Move the person to a cool place, loosen tight clothing and have them sip water slowly. Seek medical help if symptoms worsen or do not improve.
• Heat stroke is life-threatening. Warning signs can include a body temperature of 103°F or higher, confusion, loss of consciousness, hot, red skin, a rapid pulse or vomiting. Call 911 immediately and begin cooling the person with water, ice packs or cool cloths until help arrives.

Prepare Before the Hottest Days Arrive
Residents can prepare now by identifying cool places to go, checking air conditioners and fans, keeping extra water on hand and reviewing plans for outdoor work, recreation and travel. Anyone who works or spends long periods outside should take frequent breaks, watch for symptoms and check on others who may be showing signs of heat illness. To learn more, visit redcross.org/heat.
