Minnesota has recorded 2,148 tornadoes between 1950 and 2024 in NOAA’s Storm Prediction Center database, with 98 fatalities and 1,975 injuries across that span. Of those, 2 reached the maximum EF5 / F5 rating and 74 were rated EF3 or stronger.

EF / F Scale Rating Distribution

How Minnesota tornadoes break down by intensity rating. Most tornadoes nationwide rate EF0 or EF1; the rare EF3+ events account for the bulk of fatalities and damage.

Minnesota Tornadoes by Decade

Decade-by-decade tornado counts in Minnesota. Apparent increases over time partly reflect improved detection (especially after Doppler radar deployment in the 1990s) rather than purely natural change in tornado frequency.

When Minnesota Tornadoes Strike

Tornado counts by calendar month. Minnesota’s peak season runs through June (which alone accounts for 32% of all recorded tornadoes), driven by the seasonal collision of warm Gulf moisture and cooler continental air masses.

Longest Minnesota Tornado Tracks on Record

The longest continuous tornado paths recorded in Minnesota since 1950, by miles traveled along the ground from touchdown to liftoff.

Widest Minnesota Tornado Paths on Record

The widest tornado damage paths recorded in Minnesota, measured in yards across at the point of greatest width. The widest US tornado on record (the 2013 El Reno, Oklahoma EF3) reached 4,576 yards.

How to Read the Minnesota Tornado Map

• Year filter: The map opens with all Minnesota tornado tracks from 1950 to 2024 loaded. Use the Year dropdown to focus on a single season — useful for revisiting a notable outbreak.
• Track color: Lines are colored by EF / F rating. Stronger tornadoes use warmer colors and thicker lines. The legend in the bottom-right of the map shows the full key.
• Track popups: Click any track to see the date, rating, path length in miles, path width in yards, and the fatality and injury totals from NOAA’s damage survey.
• Reset view: If you pan or zoom away, click the Reset to Minnesota button in the controls bar to refit the map to the state.

Minnesota Tornado FAQ

When is tornado season in Minnesota?

Based on 1950–2024 records, the three most active months for Minnesota tornadoes are June, July, May. June alone accounts for 32% of all recorded Minnesota tornadoes. Activity outside this window is possible but uncommon.

How does Minnesota rank for tornado activity?

Minnesota recorded 2,148 tornadoes from 1950 through 2024 in NOAA’s database. Texas, Kansas, Oklahoma, Florida, and Nebraska are typically the top five states by total tornado count, while Alabama, Mississippi, and Tennessee record higher per-tornado fatality rates due to nighttime tornadoes and population exposure.

What is the difference between EF and F ratings?

The original Fujita Scale (F0–F5) was used from the 1970s through January 2007 and rated tornadoes on observed damage. The Enhanced Fujita Scale (EF0–EF5) replaced it in February 2007 with refined damage indicators that more accurately link wind speeds to structural failure modes. Both rating systems share the same ordinal levels, which is why you see them paired in the map legend and tables.

Why do older tornadoes show fewer details?

NOAA records improve substantially after the 1990s, when Doppler radar coverage expanded and damage-survey methodology was standardized. Before then, weak tornadoes in rural parts of Minnesota often went undetected, ratings were assigned retroactively from limited damage reports, and path widths and lengths were estimated rather than surveyed in detail. The dataset is most reliable for the strong tornadoes that caused damage worth investigating.
