Updated on May 20, 2015

The April 27, 2011 Deadly Tornado Outbreak

On April 27, 2011, the South and Southeastern United States witnessed the worst tornado outbreak that the U. S. has seen since the Super Tornado Outbreak of 1974. The 2011 series of storms contained over 265 tornadoes, and left over 355 people dead in it's wake. Although five states were impacted by this outbreak, the State of Alabama was especially hard hit, with the city of Tuscaloosa suffering a direct hit from a strong EF4 twister.

  • EF0---Winds: 65-85 MPH---Minor or no damage.
  • EF1---Winds: 86-110 MPH---Moderate damage.
  • EF2---Winds: 111-135 MPH---Considerable damage.
  • EF3---Winds: 136-165 MPH---Severe damage.

  • EF5---Winds: 201+ MPH---Complete destruction of buildings.

      Appearance of Torando seems to be increasing in USA, particularly in the Tornado Alley and east coast near the gulf stream geography. I have done a Ham Radio Hobby lens to link preparation for tornadoes. I voted "Like" on this valuable lens. thanks.

      so far this year, 35 states have been affected by tornadoes. and they aren't all in the south. No one is immune. You can't stop a tornado, but you can survive the aftermath. Prepare for recovery!

      My heart goes out to those poor people affected by the tornadoes. It's just crazy to fathom your house perfectly fine one minute and then gone the next.

      Tornadoes are unlikely and almost unthinkable to happen where I live. Still it's good to be informed and know what might happen even in the farthest parts of the world (which US happens to be for me).

      I'm sad about latest Tornado. Sometimes when I look at these videos it make me feel that end of world will be like this only.
