The Joplin tornado was one of the most powerful, costly, and deadly tornadoes in American history. It devastated the city, destroyed thousands of buildings, and left thousands of people without power.
The possibility of a tornado as large and destructive as the one in Joplin underscores the importance of preparing your home for emergencies and ensuring it can withstand severe weather.
Why Was the Joplin Tornado So Destructive?
There are several reasons why the Joplin Tornado was so destructive compared to the many other tornadoes that hit the USA every year. First, the tornado's intensity certainly played a role. It came in as an EF5 on the Enhanced Fujita (EF) Scale, which is the highest rating. A tornado this powerful has winds exceeding 200 mph (around 320 km/h).
In addition to high winds, the storm's urban path definitely led to much more damage than it would have if it had hit unpopulated areas. Similar to Iowa tornadoes, most tornadoes in Missouri hit open farmland or rural areas, so having one of this size and intensity hit a heavily populated area made it incredibly destructive.
The rapid growth of the storm also made it very destructive, as did the fact that the vortex was shielded by a large rainstorm, which didn’t make it very visible. As a result, by the time many people realized it was a severe threat, it was too late. Also, many residents didn’t take the initial warnings of the tornado seriously.
If you’re concerned about losing power during extreme weather, consider a portable power station like the EcoFlow DELTA Pro Ultra X. That way, you can keep your home energised even through prolonged blackouts.

How Do Tornadoes Cause Long-Term Power Outages?
The Joplin Tornado left 20,000 people without power, but how do tornadoes actually cause these long-term power outages? First, the high winds can destroy and knock over power lines, which can interrupt power for thousands of people. In addition to directly knocking over lines, tornadoes can throw other items and debris into power lines, which may damage them.
In addition to power lines themselves, tornadoes can hurl debris into substations and transformers, damaging them and leading to long-lasting outages. Tornadoes can also severely damage homes and may lead to damage to their electrical systems, causing individual outages on top of the more widespread outages that broken power lines cause.
What Lessons Did the Joplin Tornado Teach About Emergency Preparedness?
The Joplin tornado taught a variety of lessons about the importance of preparing well for emergencies. On the broad and community-wide side of things, it showed the importance of more urgent and consistent communications, improving building codes so buildings can better stand up to severe weather, and having solid post-traumatic support in place.
However, it also offered plenty of lessons to individuals, as well. For example, it showed the importance of always being prepared for anything. This means having a suitable backup power solution, keeping enough essentials in your home just in case, and mastering your emergency kit to ensure you always have the things you need to get you through emergencies.
It’s also important to have pre-planned safe meeting locations during emergencies, and have an idea of what you and your family should do in case of a severe weather event like a hurricane.
The tornado also showed us that even when spring is approaching, or already here, the storm season isn't over, so it’s important to never let your guard down or assume something like this couldn’t happen to you.
What Should You Keep Powered During Severe Weather?
When you’re dealing with severe weather, it’s tempting to try to keep your home operating as normal. While this is possible in some cases, it’s generally better to conserve your backup power and use it strategically.
The things you should keep powered during severe weather events are things that preserve food, keep you safe, and let you communicate with others. This includes your fridge, freezer, lighting, medical devices, fans/heaters, security systems, phones, computers, and radios.
While you likely have several convenient or “nice to have” electronics and appliances that you’d love to keep using during inclement weather, it’s important to prioritize your safety, health, and ability to communicate first.
What Backup Power Solutions Help During Tornado Emergencies?
To keep you connected and powered during outages caused by tornadoes or other severe weather events, you should consider having some backup power solutions at your home.
This includes small portable chargers for phones and other devices, a portable power station like EcoFlow DELTA 3 Classic for appliances, or even a whole home backup power solution to keep the entire home powered. These solutions give you peace of mind that even during outages, you don’t need to worry about losing power for days at a time.
While having these solutions is great, make sure to test them frequently to make sure they work properly. If you don’t do this, you may end up having a false sense of security that could come back to bite you the next time you find yourself in an emergency.
