What can go wrong in Las Vegas
- Extreme heat
- Summer highs above 110°F are routine, and nights stay hot. Heat is the region's deadliest weather hazard.
- Outages in heat
- Without AC, homes heat up fast. Older adults and people with medical conditions are at the greatest risk.
- Flash floods
- Monsoon storms send water racing down washes and streets with little warning.
- Earthquakes
- Southern Nevada has active faults. Large quakes are less likely than in California, but possible.
What that means for your plan
Have a plan to stay cool without power: a power station for fans, a cool room, and somewhere to go, like a family member's home or a cooling center.
Keep two weeks of water. In the desert, you'd need more of it than you think during an outage.
Never drive into flooded washes or streets. It takes very little moving water to sweep away a car.
