How Often Will Severe Weather Occur Near Me?

Risk From F2 and Greater Tornadoes

This map shows how often you would expect an F2 or greater tornado within 25 miles of you. Notice, though, that it is in days per century.

So, how many?

Central Oklahoma is colored orange, meaning 35-40 days/century. What does that mean? Let's divide 35 into 100. Looks like 2.86 years/F2 tornado. Forty into 100 is 2.5. So central Oklahoma can expect an F2 or greater within 25 miles about once every 2.5 to 3 years.

What about the really bad tornadoes - the F4s and F5s? On to page 4...
