Tornado Safety in Iowa
Tornadoes are a common occurrence in Iowa, and it is important to be aware of the dangers they pose and the steps you can take to stay safe. The National Weather Service (NWS) issues tornado warnings and watches to alert people of potential tornado activity.
A tornado watch means that conditions are favorable for tornadoes to develop. When a tornado watch is issued, you should be prepared to take shelter if a tornado warning is issued or if you see signs of a tornado, such as a funnel cloud or debris rotating in the air.
A tornado warning means that a tornado has been spotted or indicated by radar. When a tornado warning is issued, you should take shelter immediately.
Steps to Stay Safe During a Tornado Warning
- Seek shelter in a sturdy building. The best place to shelter from a tornado is in a basement or storm cellar. If you do not have access to a basement or storm cellar, go to the lowest level of your home and find a windowless interior room, such as a bathroom or closet.
- Stay away from windows. Windows can be shattered by flying debris, and you could be injured by the glass.
- Lie down flat and cover your head with your hands. If you are in a building, get under a sturdy table or desk.
- Stay informed. Listen to the radio or television for updates on the tornado warning. Do not leave your shelter until the warning has been lifted.
Tornado Shelters and Safe Rooms in Iowa
There are a number of tornado shelters and safe rooms in Iowa. These shelters are designed to provide protection from tornadoes and can save your life. If you do not have access to a basement or storm cellar, you should consider going to a tornado shelter or safe room when a tornado warning is issued.

There are many stories of resilience and recovery from past tornadoes in Iowa. One example is the story of Parkersburg, Iowa. In 2008, Parkersburg was hit by an EF5 tornado that destroyed much of the town. However, the people of Parkersburg refused to give up. They worked together to rebuild their town and make it even stronger than before.
Another example of resilience is the story of the town of Grinnell, Iowa. In 2018, Grinnell was hit by an EF3 tornado that caused significant damage to the town. However, the people of Grinnell came together to help each other and rebuild their town. They organized cleanup efforts, provided food and shelter to those in need, and worked together to repair the damage.
The stories of Parkersburg and Grinnell are just two examples of the resilience of the people of Iowa. In the face of adversity, Iowans have always come together to help their neighbors and rebuild their communities.
