Preparing for Extreme Heat Events: How to Stay Safe When Temperatures Soar
When most people think about emergency preparedness, they often focus on hurricanes, floods, tornadoes, winter storms, or power outages.
But one of the deadliest weather threats in the United States is often overlooked:
Extreme heat.
Heat-related illnesses kill hundreds of Americans each year and send thousands more to emergency rooms. For preppers, families, seniors, outdoor workers, and those living in hurricane-prone states like Florida, preparing for extreme heat should be an essential part of any preparedness plan.
Extreme heat doesn't need to be accompanied by a natural disaster to become dangerous. A few days of high temperatures combined with humidity and power outages can quickly create life-threatening conditions.
If you're serious about preparedness, it's time to add heat preparedness to your emergency planning strategy.
