How to Prepare: “Listen to NOAA Weather Radio for the latest information and look for tornado danger signs,” Scott said. Warning signs include: a dark, often greenish sky, large hail, a large, dark, low-lying cloud (particularly if rotating) and a loud roar (similar to a freight train). To stay safe in your home, Scott says you should retreat to a basement, storm cellar or an interior room with no windows on the lowest floor of your house. He also suggests practicing periodic tornado drills so everyone in your family knows what to do if one occurs. Also, “Consider having your safe room reinforced,” Scott said. “Plans for reinforcing an interior room to provide better protection can be found on the FEMA website.” Finally, you should prepare for high winds by removing dead or damaged limbs from nearby trees and moving or securing your lawn furniture, trash cans, hanging plants and anything else that can be picked up by wind.
