By decade

More tornadoes in recent decades mostly reflects better detection and reporting (Doppler radar, storm spotters, damage surveys), especially for weak EF0 tornadoes, not necessarily more storms. The 2020s bar covers only 2020 to 2024.

FEMA’s tornado risk rating

FEMA’s National Risk Index rates the tornado risk in Ashland County as very low, with a score of 14 out of 100 compared with every other U.S. county. It estimates about 0.19 tornadoes a year here and an expected annual loss of about $100,601 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.
