Key Points:
- Wibaux is the town most likely to experience a tornado in Montana.

Unlike “tornado alley“, the region in the central United States known for deadly spring storms, Montana is at relatively low risk for tornadoes. And when they occur, they tend to be smaller and less destructive than the rotating monstrosities that can topple buildings and level neighborhoods in places like Oklahoma.
However rare, residents in Montana need to be aware that tornadoes can happen anywhere at any time. And deadly tornadoes have occurred in Montana. This article shares what Montana town is most at risk for a tornado.

Tornado season in Montana occurs from late May through early August. In order to form, tornadoes need moist air near the ground combined with cooler air above. Although tornadoes can happen in any part of the state, they are less likely in the central and west, where the air is dryer. However, the eastern part of the state is more susceptible to tornadoes due to the moist air it receives from the Gulf of Mexico.
What is the Deadliest Tornado in Montana’s History?
On Father’s Day in 2010, an EF2 tornado struck a populated area in Billings, Montana. Billings is a few hours west of Wibaux. Known as the Father’s Day Tornado, the storm tore through the downtown area, causing two deaths. According to the Enhanced Fujita Scale, wind speeds reached 130 miles per hour, which is on the high side of an EF2 tornado.
The largest tornado in Montana’s history occurred in 1952 when an EF3 tornado was tracked heading through Baker, Montana. Another tornado spawned that same day in Wibaux. The tornado in Wibaux was an EF3 and caused one death.

It’s rare, but it can happen. Tornadoes won’t often form in mountainous regions, such as the Rocky Mountains in Montana. But that doesn’t mean it can’t happen. An EF4 tornado was once recorded in the neighboring state of Wyoming. The Teton-Yellowstone tornado touched down in 1987, and it was the only EF4 tornado ever recorded at a high altitude in the US.
And in 2023, a very weak tornado, actually a cold air funnel called a landspout, touched down in Montana in the Mission Mountains. Unlike the violent tornadoes most people are familiar with, this landspout produced winds up to 90 miles per hour and registered as an EF0 tornado.

How Do Tornadoes Impact Wildlife?

When a tornado hits an area, it creates a lot of destruction. The initial funnel cloud can cause animal deaths, but the aftermath of the storm may be more dangerous to wildlife than the tornado itself. Tornadoes can destroy animal habitats, such as uprooting old-growth trees where animals made their home. The lightning from the storm can cause forest fires, and heavy rains can create flash flooding.
However, even worse than that is the contamination of man-made chemicals in the environment after a tornado. Soil, air, and groundwater can be contaminated by hazardous waste from cleaning materials, asbestos from houses, workshop supplies like paint, and automotive products.
