NWS Survey Teams Release Details On Oklahoma Tornadoes

The National Weather Service says there were 25 tornadoes in the region that covers most of Oklahoma and a part of north Texas over the weekend.

One of the tornadoes is now being classified as producing EF4 damage. It is the first EF4 in the state, since May 9, 2016.

The National Weather Service says their surveys show there were:

  • One EF4
  • Two EF3
  • Two EF2
  • Nine EF1
  • Three EF0
  • 8 other tornadoes are confirmed, but the damage is still under investigation.

The Enhanced Fujita Scale or EF Scale, which became operational on February 1, 2007, is used to assign a tornado a 'rating' based on estimated wind speeds and related damage. When tornado-related damage is surveyed, it is compared to a list of Damage Indicators (DIs) and Degrees of Damage (DoD) which help estimate better the range of wind speeds the tornado likely produced. From that, a rating (from EF0 to EF5) is assigned.

The EF Scale was revised from the original Fujita Scale to reflect better examinations of tornado damage surveys so as to align wind speeds more closely with associated storm damage. The new scale has to do with how most structures are designed.
