Most Common Types of Tornadoes in Iowa
The most common type of tornado in Iowa is the weak tornado, which has wind speeds of up to 110 mph. However, strong and violent tornadoes, with wind speeds of up to 200 mph or more, are also not uncommon in the state.
Tornadoes can occur in any part of Iowa, but they are most common in the western and central parts of the state. The reason for this is that these areas are located in the path of the jet stream, which is a high-altitude wind current that can help to create tornadoes.
Tornado Safety and Preparedness
Tornadoes are violent, rotating columns of air that extend from the base of a thunderstorm cloud to the ground. They are capable of causing widespread destruction and can be deadly. It is important to be aware of the risks of tornadoes and to take steps to prepare for them.
Tornado Warnings and Watches
The National Weather Service (NWS) issues tornado warnings when a tornado has been spotted or is indicated by radar. A tornado watch means that conditions are favorable for tornadoes to develop. If you hear a tornado warning, you should take shelter immediately.
Tornado Safety Plan
Everyone should have a tornado safety plan in place. The plan should include the following:
* A designated safe place to go in the event of a tornado warning. The best place to go is a basement or storm cellar. If you do not have a basement or storm cellar, you can go to the lowest level of your home, such as a bathroom or closet.
* A way to receive tornado warnings. You can receive tornado warnings through a weather radio, television, or mobile phone app.
* A plan for what to do if you are outside when a tornado warning is issued. If you are outside when a tornado warning is issued, you should seek shelter immediately. The best place to go is a sturdy building or a ditch.
Staying Safe During a Tornado
If you are caught in a tornado, the best thing to do is to stay calm and take cover. Here are some tips for staying safe during a tornado:
