Tornado Safety and Preparedness

Tornado safety and preparedness are paramount for residents of Des Moines, given the region's susceptibility to these destructive storms. Being prepared can significantly reduce the risk of injury or loss of life during a tornado. A comprehensive preparedness plan involves several key components, starting with understanding the risks and knowing the difference between a tornado watch and a tornado warning. A tornado watch means that conditions are favorable for tornadoes to develop in the area, while a tornado warning means that a tornado has been sighted or indicated by radar and poses an imminent threat. When a tornado watch is issued, it's crucial to stay informed, monitor weather updates, and be ready to take action if a warning is issued.
