When tornadoes hit Clark County

June has brought the most, 11 of 40. About 72% touched down between 4 pm and 10 pm (Central Standard Time, as the Storm Prediction Center records it).

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.

How strong they were

F0 / EF0 Light damage: 65 to 85 mph (EF scale) 7

Tornadoes before February 2007 were rated on the original Fujita (F) scale; since then the National Weather Service uses the Enhanced Fujita (EF) scale. Wind speeds above are EF-scale estimates from damage, not measurements. See what the EF scale means.

FEMA’s tornado risk rating

FEMA’s National Risk Index rates the tornado risk in Clark County as relatively moderate, with a score of 72 out of 100 compared with every other U.S. county. It estimates about 0.45 tornadoes a year here and an expected annual loss of about $1,709,536 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.
