Wedge Tornado Binger. OK 1981


A ‘wedge’ tornado in Binger OK, on 22 May 1981. ‘Wedge’ is informal storm observers’ slang for a tornado which looks wider than the distance from ground to ambient cloud base. Although many famous ‘wedge’ tornadoes have also been violent, producing EF4-EF5 damage on the Enhanced Fujita scale, a tornado’s size does not necessarily indicate anything about its strength.
