Historic EF-5 Tornado Information | Visualizations of the Moore, OK EF-5 tornado

Two EF-5 tornadoes struck Oklahoma during May — in and near Moore on May 20th and near El Reno on the 31st. These were the 59th and 60th EF-5 (F-5 prior to 2007) tornadoes confirmed in the U.S. since reliable record keeping began in 1950. They were also the 7th and 8th EF-5 tornadoes for Oklahoma, the most of any state (seven EF-5 tornadoes have been confirmed in Alabama, and six each in Iowa, Kansas and Texas). The table below lists each EF-5 (F-5 prior to 2007) to be confirmed in the United States in the 1950-present period of record. Information on the location, date, path length and width are given.

Tornado Visualizations

Weather radar works by sending microwave pulses, then detecting returning "echoes" of targets in the atmosphere. These targets may be meteorological in nature (rain, hail, snow), and at times they may be non-meteorological (insects and debris). The KTLX radar, located in Norman, Oklahoma observed the life-cycle of the May 20th Moore EF-5 tornado due to its close proximately. The tornado occurred about 13 miles west of the radar. The radar scanned several elevations (tilts) at several-minute intervales as the storm tracked through the towns of Newcastle and Moore. This visualization utilizes NCDC's Weather and Climate Toolkit and NWS radar data to estimate the structures within the storm, based on the returns observed in the radar data.
