An F2 (now called EF2) tornado produces winds between 111 and 135 mph, strong enough to tear roofs off well-built homes, uproot large trees, and toss heavy objects like cars. It sits in the middle of the tornado intensity scale, classified as “significant” by the National Weather Service. Most tornadoes that cause serious structural damage and make the news fall into this category or higher.
How EF2 Fits on the Tornado Scale
Tornadoes are rated on the Enhanced Fujita Scale, which runs from EF0 (the weakest, with winds of 65 to 85 mph) up to EF5 (the most destructive, with winds above 200 mph). An EF2 sits right in the middle, and the National Weather Service labels it the lowest level of “significant” tornado. Everything below it, EF0 and EF1, is considered “weak,” while EF3 through EF5 are “severe” to “incredible.”
The original Fujita Scale, developed by meteorologist Ted Fujita in the 1970s, used similar categories but estimated wind speeds less precisely. The National Weather Service replaced it with the Enhanced Fujita Scale on February 1, 2007. The new version ties ratings to specific types of structural damage rather than rough wind estimates, making assessments more consistent. If you see an older tornado referred to as “F2,” it’s the same general intensity level, just rated under the previous system.
What EF2 Winds Actually Do
At 111 to 135 mph, the wind is powerful enough to cause damage that looks catastrophic up close. Entire roofs can be peeled off frame houses, leaving the walls standing but the interior exposed. Mobile homes are typically destroyed. Large trees snap at the trunk or get pulled out of the ground entirely. Cars can be lifted and thrown short distances, and heavy debris like sections of roof or appliances become airborne projectiles.
The damage pattern distinguishes an EF2 from weaker tornadoes in a few key ways. An EF1 might strip shingles and break windows, but the basic structure of a house usually holds. An EF2 compromises the structural integrity of the building itself. Walls may partially collapse once the roof is gone, garages get caved in, and outbuildings are flattened. That said, most well-anchored homes remain standing at EF2 intensity. It’s at EF3 and above where entire stories of houses start getting swept away.
Typical Size and Path
EF2 tornadoes are larger and longer-lasting than the weaker categories, though they still vary widely. Based on an analysis of over 800 EF2 tornadoes, the average path length is about 9 miles (14.3 km) and the average path width is roughly 1,130 feet (344 meters), or about the length of three and a half football fields. Some EF2 tornadoes cut narrow, short paths through open farmland, while others carve swaths through populated areas for 20 miles or more.
For comparison, EF0 and EF1 tornadoes tend to have much shorter, narrower tracks. The jump in path size from EF1 to EF2 is significant, which is part of why EF2 tornadoes cause disproportionately more damage. A wider path across a longer distance simply means more structures in the way.
How Common Are EF2 Tornadoes?
The United States averages roughly 1,200 tornadoes per year, but the vast majority are weak. EF0 and EF1 tornadoes make up about 90% of all tornadoes. EF2 tornadoes account for a smaller slice, roughly 5 to 10% of the annual total, but they’re responsible for a much larger share of tornado-related damage and fatalities. They’re common enough that most tornado-prone regions have experienced one, yet rare enough that any single EF2 event is notable for the communities it hits.
Real-World Damage
EF2 tornadoes regularly cause fatalities, especially when they strike mobile home parks or densely populated neighborhoods. In March 2022, an EF2 tornado hit the Spanish Lakes community in Florida, killing six people and destroying numerous homes. That event illustrates a common pattern: EF2 winds are survivable in a well-built structure with interior shelter, but they are deadly for anyone in a mobile home, vehicle, or poorly constructed building.
The difference between surviving an EF2 and not often comes down to where you are when it hits. Interior rooms on the lowest floor of a permanent structure provide meaningful protection at this wind speed. Mobile homes offer almost none. This is why tornado warnings urge people to leave mobile homes for sturdier shelter, even if the approaching tornado isn’t expected to be particularly strong.
How Ratings Are Assigned
Tornado ratings aren’t measured in real time. After a tornado passes, National Weather Service survey teams examine the damage along the path, comparing what they find to a set of 28 “damage indicators” built into the Enhanced Fujita Scale. These indicators cover specific structure types: one-story homes, strip malls, schools, hardwood trees, softwood trees, and so on. Each structure type has expected damage levels at different wind speeds.
Surveyors look for the worst damage along the entire path and match it to the corresponding wind range. This means a tornado’s rating reflects its peak intensity, not its average. An EF2 tornado might produce EF0-level damage for most of its path and only reach EF2 strength for a short stretch. It also means tornadoes that hit open fields with no structures to assess can be underrated, since there’s nothing to measure the damage against.
