Problem:Officially, the widest tornado on record is the El Reno, Oklahoma tornado of May 31, 2013 with a width of 2.6 miles (4.2 km) at its peak. This is the width found by the National Weather Service based on preliminary data from University of Oklahoma RaxPol mobile radar that also sampled winds of 296 mph (476 km / h) which was used to upgrade the tornado to EF5. However, it was revealed that these winds did not impact any structures, and as a result the tornado was downgraded to EF3 based on damage. However, another possible contender for the widest tornado as measured by radar was the F4 Mulhall tornado in north-central Oklahoma which occurred during the 1999 Oklahoma tornado outbreak. The diameter of the maximum winds (over 110 mph ( 49 m / s) ) was over 5,200 feet (1,600 m) as measured by a DOW radar. Although the tornado passed largely over rural terrain, the width of the wind swath capable of producing damage was as wide as 4 mi (6.4 km).
