Developing a tornado safety kit
These items would be extremely useful to have in your storm shelter, or to take with you to your storm shelter, when severe weather strikes.
Disaster supply kit: You should store your emergency supplies as close to your shelter as possible.
Battery-operated weather radio: You will want to be able to monitor the latest information directly from the National Weather Service.
A map to track storms: You will need to be able to track the progress of the storm. Because warning texts include county names, a county outline map of your area is a great thing to keep handy. You might also keep a state highway map, which includes most of the cities and towns referred to in National Weather Service warnings and statements.
Battery-operated television and/or radio: This will allow you to monitor news and severe weather information. Radios that offer television audio can be helpful. Also, many television stations simulcast their broadcasts on AM or FM radio stations.
Shoes: This will be very important if your home is damaged and you must walk across broken glass or other debris.
Identification: You may need identification to move around in the area should significant damage occur.
Your car keys: If your car is drivable, you will need the keys to be able to use it.
Other things to consider
Papers: If you have a safe room or other shelter area, you might consider storing important papers and other irreplaceable items in the shelter if space permits.
Batteries: Check and replace batteries in your weather radio, flashlights and other devices in your safety kit often, preferably twice a year. Do this at the same time you set clocks back/ahead in the spring and fall.
Maintain: Check you disaster supplies kit often to maintain fresh food and water.
Cover: Make sure you have something to cover up with. Pillows, blankets, sleeping bags or a mattress could help to protect you from falling/flying debris.
