Tornadoes can form anytime of year, but occur most frequently in April, May, and June, due to favorable weather conditions. Earlier this week a massive 200-mile-per-hour EF5 tornado hit Moore, Okla., killing some two dozen people, damaging thousands of structures, and causing an estimated $2 billion in damage. This year, twisters have already touched down in Kansas, Texas, Tennessee, Mississippi, Missouri, and Alabama. ( 46 photos total)
