FEMA’s tornado risk rating

FEMA’s National Risk Index rates the tornado risk in Guthrie County as relatively low, with a score of 64 out of 100 compared with every other U.S. county. It estimates about 0.57 tornadoes a year here and an expected annual loss of about $3,250,109 to buildings, people and farming. The index mixes how often tornadoes strike with what is exposed and how well a community can recover, so a busy rural county can rate lower than a less active city.

Staying safe

When a tornado warning is issued, act at once. Go to a basement, storm shelter or safe room. With none, use a small windowless room on the lowest floor, as far from outside walls as you can, and cover your head and neck. Mobile homes and cars are not safe places to ride out a tornado: leave early for a sturdy building or shelter.
