Clark County is home to the bustling urban center of Las Vegas (Nevada’s biggest city), North Las Vegas, Boulder, Henderson, Mesquite along with other smaller cities, rugged mountains and vast stretches of Mojave Desert terrain. The area experiences extremely hot temperatures during the summer months, which can lead to heat-related emergencies such as heatstroke and dehydration.

Dry conditions and vegetation make the area susceptible to wildfires, especially in rural and mountainous regions.

Smoke associated with wildfires can contribute to COPD exacerbations during heavy smoke conditions, especially in older populations. Visit Rural NV Smoke for up-to-date smoke conditions in the area.

Heavy rain, especially during the monsoon season, can lead to flash floods in parts of Clark County. These floods can be sudden and dangerous.

You can help to protect yourself by:

• Drinking plenty of fluids, staying out of the sun, and finding an air-conditioned place
• Staying informed about weather forecasts
• Thinking about how a flood could affect you
• Planning for your needs in the event of evacuation, being trapped at home, or losing power
• Preparing defensible space around your home
• Staying informed about wildfires

It’s essential for residents and visitors in Clark County, particularly in Las Vegas, to stay informed about potential emergencies and have an emergency preparedness plan in place, including having a network, knowing evacuation routes, having emergency supplies, and staying tuned to local news and authorities for updates during such events.

Local authorities, including the Las Vegas Metropolitan Police Department and Clark County Emergency Management, provide information and guidance during emergencies.
