Preparing for Tornadoes in Missouri
Tornadoes are a natural disaster that can strike at any moment, and in Missouri, they have a history of causing significant damage. As such, it is crucial for Missourians to prepare themselves and their homes for tornadoes.
One of the most important aspects of tornado preparation is having an emergency plan in place. This plan should include a designated safe space within your home, such as a basement or storm shelter, where you and your family can go during a tornado. You should also have a way to receive weather alerts, whether it be through a weather radio, smartphone app, or local news outlet. Another option is a location-based alert system, like StormWarn, which sends you a notification when your home is in the dangerous “polygon” area determined by the National Weather Service for each storm. This avoids the feeling that you’ve sheltered as a “false alarm” when the area that received a warning was actually much larger than the affected area.
Another important aspect of tornado preparation is ensuring that your home is structurally sound. While most people won’t go to the trouble and expense of having reinforced windows and doors, it is a good idea to make sure they can withstand high winds and that your home’s roof is in good shape. Be sure to secure outdoor items such as patio furniture and grills that could become dangerous projectiles in high winds.
It is also essential to have an emergency kit stocked with supplies such as non-perishable food, water, first aid items, and a flashlight in case of power outages. Luckily, most people spend only a few hours in a tornado shelter, so a large stockpile isn’t needed. It's all part of your family's tornado preparedness plan.
By taking the time to prepare for tornadoes, residents of Missouri can help ensure that they and their families are ready to face this natural disaster.
