2013 Moore, Oklahoma, tornado: Facts, FAQs, and how to help

On May 20, 2013, one of the deadliest tornadoes in Oklahoma’s history raked a 14-mile path of destruction through the southern areas of Oklahoma City and decimated the city of Moore, causing $2 billion worth of damage. It flattened one elementary school, where no fatalities occurred, then hit another school, where a wall collapsed and killed seven children. The Moore, Oklahoma, tornado was categorized as an EF5, a rare twister packing estimated wind speeds greater than 200 mph. It killed 25 people and created a swath of destruction, including 300 demolished homes.

Less than two weeks later, the largest ever-recorded tornado — coupled with severe rain and flooding — struck central Oklahoma and caused further damage and loss of life, killing nine during the tornado and 14 people in the flooding.

Brief history of Oklahoma tornadoes

Oklahoma typically experiences around 60 tornadoes a year. It is part of Tornado Alley, a nickname for an area in the southern plains of the central United States, where tornadoes are common. Most tornadoes, about 77%, don’t cause death or widespread damage. On occasion, the strongest tornadoes strike heavily populated areas and wreak devastating destruction.

1947: The deadliest tornado in Oklahoma’s history struck on April 9, 1947, killing 116 people and injuring 782 after killing at least 69 people in Texas.

1999: On May 3, 1999, a series of nearly 60 tornadoes struck central Oklahoma within 24 hours, largely in the southern metropolitan areas of Oklahoma City, including Moore. One of these, the Bridge Creek–Moore tornado, killed 36 people, destroyed 1,800 homes, and damaged another 2,500 homes.

May 20, 2013: The 2013 Moore tornado followed a path similar to that of the 1999 Bridge Creek–Moore twister. After three days of severe weather, several supercell thunderstorms developed. One of these produced a tornado that touched down in Newcastle and rapidly turned violent. For 40 minutes, the tornado tracked a devastating path through Newcastle, Moore, and southern Oklahoma City, damaging two schools, destroying 300 homes, and claiming 25 lives.

May 31, 2013: Additional tornadoes hit central Oklahoma, including the largest ever recorded tornado — the El Reno tornado, which stretched 2.6 miles wide and killed nine people. This tornado stirred up accompanying tornadoes and storms that caused flash flooding, killing 14 people around Oklahoma City and compounding recovery efforts.
