The most deadly weather events in the U.S. are extreme heat, according to FEMA. However, because of its lack of the same devastation-causing ferocity as wildfires or tornadoes, hot weather is often easy to underestimate. As climate change continues to fuel heat waves, they are now more prevalent, from two per year on average in the 1960s to six per year today. Even worse, compared to the 60s, these events are more prolonged and intense. 

Emergency preparedness for extreme hot weather can mean life or death, as current statistics show that millions of Americans live in areas that are vulnerable. Extreme heat warnings for millions of people were issued, this summer as record-breaking heat waves enter the third year in a row, and thousands lose power.

As global temperatures continue to rise, hot weather is inevitable, and long-term power outages are imminent. Therefore, monitoring and preparing for this ever-increasing trend is prudent. Read on to learn the best emergency preparedness practices for hot weather, how to; stay informed, cool, and hydrated, dress appropriately, and put contingency plans in place for power outages or other emergencies.

Getting Ready with Emergency Preparedness For Extreme Hot Weather

When getting ready with emergency preparedness for extreme hot weather we want to do three things.

  1. Make a Plan
  2. Build a Kit
  3. Be informed

Extreme heat in our weather often results in the highest annual number of deaths among all weather-related disasters. That is a pretty sobering statement from FEMA and something to not take lightly. We also need to consider emergency preparedness for extreme hot weather emergencies.

It is essential to have a plan to respond when you live in places that are susceptible to extremely hot weather. Building a kit means having a checklist and a preplanned kit, package, box, or bag available to you in an extreme heat emergency or disaster with special items that are necessary for your protection and communication.

Being informed about upcoming weather events and possible problem scenarios is always essential for your safety. Television, internet, radio, and cell phone communication are the best way to stay informed of the latest information.

Using Emergency Preparedness Technology For Extreme Hot Weather

Stay connected and informed with emergency preparedness technology like cell phones, weather radios, TV, and the Internet.

We use technology all of the time to monitor our weather from a simple digital thermometer to complex AI algorithms that monitor the worlds weather for entities like the National Weather Service in the U.S.

We also use technology for emergency response with our communications, two way radios, all the way to our weather radios.

Technology is essential for the early warning system to notify everyone including the news outlets of impending extremes in areas of the planet and in the U.S. that can get extremely hot and cause actual death to people who are unprepared or cannot respond.

We also constantly have new technology and its effect and strain on the national power grid and the possibility of overwhelming the grid at peak times for air conditioning and electric vehicle charging at peak load hours. Our technology monitoring is necessary to prevent rolling blackouts for power grid over use.

The Global News on Droughts and Hot Weather

Whether you are from the U.S. East or West Coast or somewhere in the middle, we have all experienced hot weather. It seems like lately it is getting more and more prevalent.

You must have come across the heatwave chaos hitting America year after year if you’re current with the news or live in a hot place. Texas’s San Angelo airport experienced two weeks straight with heat index temperatures as high as 45.6C (114F), three degrees higher than usual.

In 2022 more than 8 million Americans experienced temperatures above 125 degrees, but by 2053 over 100 million Americans could expect that kind of heat annually.

After breaking records in Texas, the heatwave moved into states like Arkansas, Oklahoma, Missouri, and Louisiana, as well as the entire west coast. With temperatures predicted to rise 5-10 degrees Celsius above the climatological average and over 50 million people placed under intense heat advisories, you might be worried if you live in the U.S. 

Growing Up in Hot weather Areas Prepares You Too

Growing up in Las Vegas, Nevada, I have plenty of experience with extremely hot weather. I can remember the sound of the Cicadas in the summer when I was a little kid and the stifling heat. Standing under mulberry trees for shade and not understanding that it was so hot. Watching the asphalt streets “breathe” as we call it from 120 degree July and August summers.

I also remember the feeling of being lightheaded and the feeling like you were going to pass out from being in the sun or the heat all day. Often, the air conditioning was swamp coolers as opposed to actual air conditioners and although blowing cold air if you are under one, they do not work the same as air conditioners.

My family was always about emergency preparedness and we were always well stocked with emergency supplies and would discuss as a family. During “Hell Weeks” in High School football practice in August, they would give us salt tablets to help keep us hydrated with potassium. In some ways, the technology is not a lot better than a salt tablet still to this day.
