Tornadoes occur on every continent, except for Antarctica. Unfortunately for those of us living in the United States, our nation has the highest incidence of tornados in the world. Due to America’s size, central flat lands, and intersecting weather patterns, the conditions exist for tornados to be a common and frequent occurrence. Though the area known as “Tornado Alley,” which comprises Nebraska, Kansas, Oklahoma, and northern Texas is most associated with this destructive weather phenomenon, only Kansas ranks in the top-five states with the highest average tornados per 10,000 sq. mi. from 1991–2010, according to the National Climactic Data Center. The other four? Illinois, South Carolina, Maryland, and Florida, which holds the top spot. My point is: Just because you don't live on the plains doesn't mean you shouldn't prepare for unpredictable spring tornadoes. Here's how to pick shelter spots in your home and stay alert to this hazard.
