Tornado Damage by State: 14,271 Tornadoes in NOAA Records, 2015 to 2025

Illustration: snapped trees and a damaged outbuilding along a tornado path.

The finding

Ranked as tornado damage by state, Texas leads NOAA’s Storm Events records for 2015 to 2025 with $2.34 billion of reported property damage, 18% of the $13.3 billion national total, followed by Missouri at $1.94 billion. Per resident, Missouri ranks first at $310 (NOAA, Census). The dollar ranking and the human toll diverge: Kentucky recorded the most tornado deaths (98) yet ranks 20th for damage, and 31% of its county records carry no damage estimate at all (NOAA).

Key findings

  1. Texas leads with $2.34 billion of reported tornado property damage from 2015 to 2025, and also logged the most tornadoes, 1,363 (NOAA).
  2. Per resident, Missouri tops the ranking at $310 of reported damage per 2025 resident, ahead of Tennessee ($263) and Arkansas ($241); Texas ranks 8th (NOAA, Census).
  3. Kentucky recorded 98 of the 563 tornado deaths, more than any other state, but 31% of its county records have no damage estimate, so its $65.6 million total is a floor, not a measure of loss (NOAA).
  4. The deadliest single tornado in the file, an EF4 on the ground for 169 miles across Kentucky and Tennessee in December 2021, is linked to 58 deaths yet carries $25,000 of reported damage: 12 of its 14 county segments have no estimate (NOAA).
  5. EF3 and stronger tornadoes are 2.1% of the 14,271 tornadoes but carry 77% of deaths and 63% of reported damage (NOAA).
  6. The 10 costliest tornadoes hold 54% of the $13.3 billion reported, and the single costliest (Illinois and Missouri, May 2025) holds 12% (NOAA).
  7. In Mississippi, 37% of tornadoes fall between November and February, against 16% nationally (NOAA).
  8. Tornadoes that began between 18:00 and 06:00 local time are 42% of the count but 65% of deaths (NOAA).

Counting tornadoes, not rows

The Storm Events files hold 16,489 Tornado rows for 2015 to 2025, but that is not the number of tornadoes. Each row is one tornado in one county. When a tornado crosses a county line, the row for the county it leaves names the next county in the TOR_OTHER_CZ fields, and the next county gets a row of its own (NCEI Storm Data bulk CSV format documentation). Chaining those links gives 14,271 tornadoes (NOAA). Of them, 1,789 crossed at least one county line and 210 crossed a state line; the longest chain runs through 14 counties (NOAA).

This report uses each unit for what it measures. Dollars, deaths and county rankings are summed over rows, because each row carries its own figures and nothing is entered twice. Counts, EF ratings, path lengths and seasonality use tornadoes. A tornado that crosses a state line is counted once in each state it touched, so state counts add up to more than the national 14,271. Of 2,251 links, 20 found no partner row and are left as separate tornadoes (NOAA). Source: NOAA NCEI Storm Events.

The state ranking by reported damage

The 12 states with the most reported tornado property damage hold 89% of the 50-state and DC total of $13.3 billion for 2015 to 2025 (NOAA). Texas leads on dollars and on tornado count. Oklahoma, second by count with 940 tornadoes, ranks 9th on dollars. Source: NOAA NCEI Storm Events.

Per resident: a different top ten

Raw totals favour large states. Divided by 2025 population, and limited to states with at least 50 tornadoes, Missouri leads at $310 of reported damage per resident over 11 years, then Tennessee, Arkansas and Iowa (NOAA, Census). North Dakota has the most tornadoes per million residents (354). Sources: NOAA NCEI Storm Events; Census Vintage 2025.

Where the dollars are missing

NOAA separates a recorded zero from a missing estimate. Of 16,489 Tornado rows, 7,656 (46%) carry a positive damage figure, 5,939 are entered as 0.00K and 2,894 are blank, meaning no estimate was entered (NOAA). The median positive estimate is $50,000 (NOAA). Source: NOAA NCEI Storm Events.

The gaps are not spread evenly. In Kentucky, the state with the most tornado deaths, 31% of county records are blank, and the deadliest tornado in the window shows it most clearly: it began in Obion County, Tennessee, in December 2021, tracked 169 miles, is linked to 58 deaths and 515 injuries, and carries $25,000 of reported damage. 12 of its 14 county segments have no estimate (NOAA). Any ranking by reported dollars gives that tornado almost no weight. Source: NOAA NCEI Storm Events.

A blank is not a zero. NWS Instruction 10-1605, Storm Data Preparation (26 July 2021) sets out how damage estimates are entered (section 2.7), and the file does not say why one is missing. State totals in this report are therefore floors for reported damage, not measures of total loss. For the largest events valued on a different basis, see the billion-dollar disaster record.

Strength: the EF scale and the losses

Each tornado is rated on the Enhanced Fujita scale from surveyed damage (NOAA Storm Prediction Center, Enhanced Fujita Scale); here a tornado takes the highest rating among its county segments. EF0 and EF1 tornadoes make up 79% of the count and 9% of reported damage (NOAA). EF3 and stronger make up 2.1% of the count, 63% of damage and 77% of deaths (NOAA). The window holds a single EF5 rating: North Dakota, June 2025, with 3 deaths and no damage estimate in the file (NOAA). Source: NOAA NCEI Storm Events.

After dark

Begin times in the file are local standard time. Of 14,271 tornadoes, 6,007 (42%) began between 18:00 and 06:00; those tornadoes account for 367 of 563 deaths (65%) and 158 of 299 EF3 or stronger tornadoes (NOAA).

What the records say for restoration work

For contractors, the volume sits at the low end of the scale. EF0 and EF1 tornadoes are 79% of the count; 62% of EF1 tornadoes carry a positive estimate, with a median of $75,000, and 40% of EF0 tornadoes, with a median of $20,000 (NOAA). The large losses sit higher: the 1,494 tornadoes rated EF2 or stronger, 10% of the count, carry 91% of reported damage (NOAA). Source: NOAA NCEI Storm Events.

Storm Events damage is one figure per county record. It does not split wind and debris damage from water entering through breached roofs and broken windows, or contents from structure, so the share of tornado losses that becomes water damage work cannot be read from this file. For how work volume swings from year to year across hazards, see the restoration demand volatility index; for federal recovery spending by state, FEMA spending by state. Sibling reports cover hurricane damage by state and flash flood deaths by state, and the full set sits on the data hub.

Data treatment

Rule Records affected Treatment
Blank DAMAGE_PROPERTY (no estimate) 2,894 Excluded from damage sums and medians; shown as a share.
DAMAGE_PROPERTY entered as 0.00K 5,939 Kept as zero in totals; medians use positive estimates only.
County links with no partner row 20 Left as separate tornadoes.
Rows with no begin coordinates 9 Linked on time only where a link names them.
Island areas in the STATE column 10 Reported separately, not ranked.
Rows not keyed to a county (CZ_TYPE not C) 0 Would be excluded; none occur.
Duplicate EVENT_ID 0 None found, so no record is counted twice.
Rows missing the tornado columns 0 Would be treated as unrated; none occur.
Partial year 2026 990 Excluded from every ranking; reported in one labelled note.

Method

How we counted. We downloaded the NOAA NCEI Storm Events details files for 2015 to 2026 on 6 October 2026 and kept rows with EVENT_TYPE Tornado (16,489 rows, 2015 to 2025). Each row is one tornado in one county. We read TOR_F_SCALE, TOR_LENGTH (miles), TOR_WIDTH (yards), the TOR_OTHER_CZ fields and begin and end times and coordinates from the same files. A row naming a next county was chained to the Tornado row in that county beginning within 120 minutes of its end time and within 0.5 degrees of its end point, nearest first, giving 14,271 tornadoes. A tornado’s rating is its highest segment rating; path length sums segments; width is the widest segment. Deaths are DEATHS_DIRECT plus DEATHS_INDIRECT summed over rows. DAMAGE_PROPERTY strings such as 10.00K were converted to dollars; blanks were excluded from sums and medians and zeros kept. Damage is nominal and not inflation adjusted; crop damage is not used. Rankings cover the 50 states and DC; island areas are reported separately. Per resident figures divide 11 years of totals by 2025 population from the Census Bureau Vintage 2025 estimates. Night means a local standard begin time from 18:00 to 05:59. 2026 is a partial year and is excluded from every ranking. Source: NOAA NCEI Storm Events.

What this does not show

What this does not show

  • Reported damage, not total loss. Amounts are NWS estimates from emergency managers, media and other sources, in nominal dollars. A blank means no estimate; state totals are floors.
  • Tornado counts are reconstructed. Chaining county segments relies on the TOR_OTHER fields, times and coordinates. A missed or wrong link changes the count by one; official Storm Prediction Center tornado counts may differ slightly.
  • Ratings are as stored. EF ratings come from damage surveys, can be revised, and reflect the strongest damage found, not dollars. EFU tornadoes could not be rated.
  • Rates are approximate. 11 years of totals divided by one year’s population; no land area adjustment is made.
  • No split by cause of loss. The file does not separate wind, debris and water intrusion damage, or say who paid for repairs.
  • Not insurance claims or federal aid. Insurer payouts, FEMA grants and SBA loans are different datasets. For decisions, consult FEMA, your state emergency management agency or your insurer.

Questions this report answers

Which state has the most tornado damage?

Texas, with $2.34 billion of reported property damage in NOAA Storm Events records from 2015 to 2025, followed by Missouri at $1.94 billion. Per resident, Missouri ranks first (NOAA NCEI).

Which state has the most tornado deaths?

Kentucky, with 98 deaths from 2015 to 2025, followed by Mississippi with 68 (NOAA NCEI).

How many tornadoes hit the US each year?

An average of 1,297 a year in NOAA records from 2015 to 2025, after joining county segments of the same tornado, ranging from 983 in 2016 to 1,787 in 2024 (NOAA NCEI).

How much tornado damage comes from EF3 or stronger tornadoes?

63% of reported damage and 77% of deaths, from 2.1% of tornadoes, 2015 to 2025 (NOAA NCEI).

Why does Kentucky’s tornado damage look low?

31% of its tornado records have no damage estimate in the file, including most segments of its deadliest tornado, so reported dollars understate the loss (NOAA NCEI).

When is tornado season in the South?

The records show more cool-season tornadoes in the South. In Mississippi, 37% of tornadoes from 2015 to 2025 fell between November and February, against 16% nationally (NOAA NCEI).
