5 Violent EF4 Tornadoes Have Now Hit The US In 2025. Is That Unusual?
-Defining Violent Tornadoes: While all tornadoes are dangerous, meteorologists reserve "violent" for those with the two highest ratings on the Enhanced-Fujita scale - EF4 or EF5. That's because these strongest tornadoes are capable of devastating damage, such as crushing and throwing vehicles, leveling well-built homes, even sweeping foundations clean. These select few tornadoes are estimated to have peak winds of 166 mph or higher.
-This Year's EF4 Tornadoes: Two of them struck northern Arkansas on the night of March 14. The following day, EF4 damage was found from a tornado that tracked from Tangipahoa Parish, Louisiana, to Covington County, Mississippi. May 16 had two EF4s, one south of Marion, Illinois, and another that devastated parts of Pulaski and Laurel counties in southeast Kentucky.
-More Than The 10-Year Average: There have been anywhere from zero to six EF4-rated tornadoes each year from 2015 through 2024, so this year is on the higher end of that range for the past decade. The average over that time is about 3 per year, which is 2 fewer than we've seen in 2025.
-Two Outlier Years: Looking farther back in time to when the Enhanced Fujita scale was implemented in early 2007, there have been as been as many as 23 violent tornadoes in 2011 and 13 in 2010. Those two outlier years skew the average higher to about 5 to 6 EF4 tornadoes per year since 2007.
-Violent Tornadoes Are Overwhelmingly Deadlier: From 2007 through 2024, this tiny fraction of tornadoes was responsible for more than half of all U.S. tornado deaths. 828 people were killed by EF4 or EF5 tornadoes in that time compared to 649 for all tornadoes rated EF0 to EF3, combined.
-Top States: It should come as no surprise where violent tornadoes occur most often. From 1950 through 2024, the conventional Plains "Tornado Alley" states of Oklahoma, Texas, Iowa and Kansas had the largest number of violent tornadoes. Elevated violent tornado counts also extend eastward into the Ohio Valley and a southern corridor that includes Alabama, Mississippi and Tennessee.
-No EF5s In More Than A Decade: The last one to reach this rating hit Moore, Oklahoma, in the Oklahoma City metro area on May 20, 2013.
-Why So Long?: A recent study found that may be due as much to the more stringent engineering criteria of the Enhanced Fujita scale compared to the pre-2007 Fujita scale. In essence, it appears a destroyed building had to be built beyond standard construction codes to be rated EF5 today.
-An Example This Year: The photo below shows a two-story home built in 2003 that was completely swept away by a tornado that struck south of Marion, Illinois, May 16, 2025. Given nothing is left, it might make you immediately think it should be an EF5.
The National Weather Service storm survey stated, "The extreme tree stubbing combined with the typical construction methods of the home support a peak wind speed rating of 190 mph". Since the home had typical construction methods, the damage was just short of what can be rated as an EF5, which contains winds greater than 200 mph.

On This Date: A Violent Tornado In Wyoming's Mountains
If I mention the phrase "violent tornado," what state first comes to mind — Oklahoma, Alabama or maybe Texas? On July 21, 1987, 38 years ago this afternoon, a tornado touched down in northwestern Wyoming just east of Grand Teton National Park. Tornadoes can happen in mountainous terrain, but this was an exceptional twister by high country standards. It tore a 24-mile path in 26 minutes from east of the town of Moran across the Continental Divide at just over 10,000 feet elevation before it lifted in the southeast edge of Yellowstone National Park. Nobody was killed, but nine campers witnessed a "fast-approaching train-like noise" along with large hail, according to WyoFile. According to the U.S. Forest Service, 1 million trees were uprooted in a 15,000-acre swath, some of which you see in the photo below. That grabbed the attention of the father of tornado science, Theodore Fujita. Fujita coordinated three aerial surveys in the weeks after the tornado. In a study released just over 18 months later, he rated the tornado F4 with peak winds estimated at over 207 mph using the pre-2007 Fujita scale. Fujita assigned this rating based on observations of "uprooted large trees, spattered by wind-blown topsoil and debarked." This remains America's strongest high-elevation tornado on record. Fujita found the damage path was up to 1.6 miles wide, consisting of "swirl marks" indicative of the tornado, as well as 72 separate microburst outflows within the damage swath. Damage from the tornado was estimated at $2.5 million. According to WyoFile, many of the downed trees were consumed the following summer by the Yellowstone wildfires of 1988.

Utah ‘firenado' with 122-mph winds leaves behind terrifying path of destruction
A surging wildfire ripping through eastern Utah wilderness over the weekend triggered a rare 'firenado', unleashing a terrifying mix of wind and flames that left one home and several other outbuildings severely damaged. The Deer Creek Fire had already burned several thousand acres just north of La Sal on Saturday when the column of flames and hot gases began spinning, creating the surreal sight of a firenado. Advertisement 'One of our firefighters captured this unusual phenomenon of a fire vortex tearing through pinyon-juniper woodland on the Deer Creek Fire, just outside of La Sal,' said officials with the Utah Bureau of Land Management. The firenado did significant damage as it wreaked havoc on a neighborhood caught in the blaze. The National Weather Service estimated that wind speeds inside the twister reached 122 mph – strong enough to rate an EF-2 on the Enhanced Fujita scale. What's worse, instead of typical tornadoes that may only spend moments to seconds blasting a neighborhood as the storm blows through, this firenado was nearly stationary, spending 12 minutes swirling its flame-infused fury. 4 On Saturday, July 12, a fire-induced tornado developed within the Deer Creek wildfire near La Sal, Utah. National Weather Service Advertisement 4 The tornado was on the ground for approximately 12 minutes from 1:03-1:15 PM MDT and remained nearly stationary. Dwellings and outbuildings in the area sustained a mix of fire and wind damage. National Weather Service 'Dwellings and outbuildings in the area sustained a mix of fire and wind damage,' said NWS meteorologists in Grand Junction, Colorado, who later surveyed the damage. 'Many of the affected structures burned after the tornado occurred, but wind damage sustained by the remaining structures resulted in the tornado being given an EF-2 rating.' Luckily, residents had already evacuated with the approaching wildfire and no one was injured, NWS officials said. Fire whirls or 'firenados' are spinning columns of hot air and gases rising up from a fire, according to the National Wildfire Coordinating Group. When the air and gases rise, they also carry up smoke, debris, and even fire, as seen in the vortex of fire in the video. Advertisement 4 Dwellings and outbuildings in the area sustained a mix of fire and wind damage. National Weather Service 4 Many of the affected structures burned after the tornado occurred, but wind damage sustained by the remaining structures resulted in the tornado being given an EF-2 rating. National Weather Service The vortices can be as small as under one foot wide to over 500 feet wide, the NWCG said. Fire whirls on the larger side can be as strong as a tornado, as evidenced on Saturday. One of the largest and most destructive fire whirls occurred in 2018 during the Carr Fire in Redding, California, the National Weather Service said. It had wind speeds of about 143 mph, equivalent to those found in EF-3 tornadoes. Advertisement Tornadoes in any form, be it thunderstorm or wildfire-driven, are rare in Utah. The firenado was only the second twister to be given an EF-2 rating in Utah since the Enhanced Fujita scale was implemented in 2007. Prior to that, only nine other tornadoes had been rated at least an F2 on the original Fujita Scale since 1950. Meanwhile, firefighters are still battling the Deer Creek Fire, which had burned more than 15,600 acres as of Thursday morning's update. The blaze is about 7% contained. It's one of eight large wildfires burning in Utah that have scorched over 60,000 acres so far this summer.

The most destructive tornado in New England history struck Worcester 70 years ago. Here's what happened.
The violent tornado was on the ground for 84 minutes and grew to over a mile wide, claiming 94 lives. Thousands of buildings were destroyed. Back then, F4 tornadoes were estimated to have maximum wind speeds between 207 and 260 mph. (Since 2007, when the Enhanced Fujita scale came out, both wind speed and destruction are considered when rating a tornado. There's a good chance that the Worcester tornado would have been rated an EF-5 based on the updated system.) There has only been one tornado since that has claimed more lives: the Joplin, Missouri twister of 2011, which killed more than 100 people. Weather setup Advertisement The Worcester tornado was one of four to strike the region that afternoon, spawning from a strong area of low pressure with a powerful cold front interacting with excessive humidity. According to reports from that day, dew points were well into the 70s, priming the atmosphere for explosive storms. When you forecast the possibility of tornadoes, you need four main ingredients — wind shear, lift, instability, and moisture. Wind shear is the change in wind speed and direction with height in the atmosphere. Lift refers to a mechanism to drive moist, warm air upwards in the atmosphere. Instability and moisture are more obvious, but the more humid it is, the more unstable the atmosphere becomes. All four ingredients were present across New England that day. Advertisement It was also the first-ever tornado warning issued by the National Weather Service (known as the U.S. Weather Bureau back then) in New England, but the warning came only after the twister had touched down — debris was already falling out of the sky at the Blue Hill observatory deck — meaning it was too late for many people to seek shelter. A very strong area of low pressure highlighted the surface weather map of New England on June 9, 1953. NWS Path of destruction The monster tornado began its path of destruction over the Quabbin Reservoir near Petersham around 4:30 p.m., tracking to the southeast and crashing into the towns of Barre and Rutland. By the time the clock struck 5 p.m., the tornado had strengthened significantly in Holden, leveling whole neighborhoods. The path of the 1953 Worcester tornado. TornadoTalk The tornado reached maximum strength and severity when hitting Worcester, with Assumption College in its crosshairs. The northern side of the campus, made of heavy brick walls, was leveled. Assumption College just after 5 p.m. on June 9, 1953. Assumption University What's interesting here is that the Worcester hills, specifically Burncoat, may have amplified wind speeds at this point in the tornado's life, increasing the damage and possibly reaching F5 intensity. Hills can impact a tornado's strength, and increasing elevation could have led to stronger winds. The massive tornado continued into Shrewsbury and Westborough, destroying many homes and businesses until finally fading near the Southborough/Framingham line. Three other tornadoes formed that same day, one in Southeastern Mass., an F3, and two in Southeastern New Hampshire — an F3 and F1. Aftermath To put into context just how powerful this tornado was, debris was found as far away as Eastham on Cape Cod, a signal of just how strong the vortex and updraft were from this storm. Books were found — confirmed to be from Worcester — in Provincetown. Advertisement It took years for the region to recover. More than 4,000 buildings were destroyed by the nearly hour-and-a-half tornado, causing the equivalent of $550 million in damage if the event occurred in 2025. June 10, 1953: The worst tornado in New England's history ripped a 25-mile path of death and destruction through six Central Massachusetts communities on June 9, 1953. The tornado which touched down at 4:25 near the town of Petersham continued for 84 minutes ultimately killing 94 people and leaving over 15,000 homeless. This picture from Burncoat Street in Worcester shows the pile of debris left in its wake. The Boston Globe/Boston Globe Assumption College was relocated to Salisbury Street, while Quinsigamond Community College was built in the years after on the land where Assumption once stood. The Worcester tornado bookmarked a multiday severe weather event across the country, spawning epic tornadoes that have now been cemented in the weather history books. The event in early June 1953 spearheaded rapid changes to how the country handled forecasting, including the development of a storm spotter network that dramatically improved the timing of tornado warnings to help people find cover sooner.
