Clark County sees 7 heat-related deaths; officials urge caution through heat warning
The Southern Nevada Health District is urging residents to take caution amid the current excessive heat warning.
Clark County has so far in 2023 reported seven heat-associated deaths. In 2022, there were 152.
"Heat-related illness occurs when a person’s body temperature rises faster than it can cool down, which may lead to heat exhaustion or heat stroke, ultimately damaging the brain or other vital organs. Older adults, the very young, and those with mental illness or chronic medical conditions have the highest risk of heat-related illness. However, anyone can be affected if participating in strenuous physical exercise in hotter weather," a health district spokesperson wrote in a media release.
The forecast high temperatures are expected to stay above 110 degrees Fahrenheit through at least next Thursday. The excessive heat warning expires 8 p.m. Tuesday.

A Twitter user asked the National Weather Service if monsoon moisture is possible following the heat wave. A representative responded, "There are signs it will drift eastward next week, which will allow for slightly less hot temperatures, and could also open the door for southeast winds to bring in some moisture. How far east the high moves will help determine whether thunderstorms result."
In two videos posted Wednesday, NV Energy Senior Meteorologist Alex Hoon said they are prepared for the heat wave and any potential outages.

- If unaccustomed to working or exercising in a hot environment, start slowly and gradually increase the pace
- Avoid being out in the sun for extended periods
- When planning extended outdoor activities, bring an adequate supply of water. Drink plenty of water at regular intervals, regardless of activity level
- Avoid alcohol or liquids that contain high amounts of sugar
- Plan well-balanced light meals
- Check the local weather forecasts and plan activities accordingly
- Check on the status of homebound neighbors and relatives
Cooling stations will also be available through the weekend at various locations throughout the Las Vegas Valley.
