Tornadoes in Houston: 430 Since 1950, but Rarely a Killer

Houston has recorded more tornadoes than Chicago, St. Louis or Nashville — 430 since 1950. Yet it has suffered just 12 tornado deaths in 74 years and exactly one F4. The reason is hiding in the calendar: many of Houston’s tornadoes are spun up by landfalling hurricanes, and hurricane tornadoes stay weak.

Houston is, by raw count, one of the most tornado-prone big cities in America. Pull the NOAA Storm Prediction Center archive for the Houston metro touchdown box and it returns 430 tornadoes since 1950 — more than the Chicago metro (176) or the St. Louis metro (208). That works out to roughly six tornadoes a year in and around Harris County.

And yet Houston is not a place people think of as tornado country — because its tornadoes almost never turn deadly. In 74 years the metro has recorded just 12 tornado deaths and a single violent tornado, an F4 in November 1992 that killed no one. Compare that to the 71 deaths in the Chicago metro or the 39 in St. Louis. Houston’s story is frequency without violence, and the explanation runs through the Gulf of Mexico.


The strongest and deadliest Houston-area tornadoes

From the SPC record for the metro box (Harris County and the surrounding suburban counties). What stands out is how short this list is: with only one F4 and 12 F3s in the entire archive, even Houston’s worst tornadoes rarely killed. Location labels come from each tornado’s touchdown coordinates; SPC totals run slightly under press tallies because the archive counts confirmed segments only.

Of the metro’s 430 tornadoes, 232 were rated F0 and another 138 were F1 — 86% of them were the weakest two categories on the scale. That is a radically different profile from the Plains, where a much larger share reach F2 and above.


The hurricane fingerprint: why Houston’s busiest years are storm years

Here is the single most revealing fact in the record. The two busiest tornado years in Houston history were 1983 and 2017 — and both were hurricane years. In August 1983, Hurricane Alicia came ashore at Galveston as a Category 3 and spun up 15 tornadoes in the Houston metro box that month alone. In 2017, Hurricane Harvey stalled over the region and produced 11 August tornadoes in its outer rain bands. Go back further and the pattern holds: the metro’s September 1961 F3 was thrown off by Hurricane Carla, and 2024’s Hurricane Beryl added another cluster.

Tropical cyclones are tornado factories. As a hurricane’s circulation moves over land, the friction and wind shear in its rain bands spin up dozens of small, brief tornadoes — almost all of them F0 or F1, on the ground for a minute or two. They inflate a metro’s tornado count without producing the long-track, high-end monsters that kill in Oklahoma or Alabama. Houston sits directly in the landfall zone for Gulf hurricanes, so it collects these weak spin-ups year after year. That is the mechanism behind the paradox: a huge count, a tiny death toll.

It is the same Gulf moisture engine that drives the region’s broader weather extremes — see our 2026 hurricane season tracker and Texas hurricane history for how often storms take aim at the upper Texas coast.


Houston’s tornado calendar has two peaks

Most metros have one spring peak and go quiet the rest of the year. Houston has a clear May maximum (72 tornadoes) from the tail of spring severe season — and then an unusual second plateau in August, October and November, each with 48. The August bump is the tropical signature; almost every inland city is dead quiet in late summer. Monthly counts from the SPC data:

That August–November tail is the hurricane season overprint on top of the normal spring peak. For how Texas as a whole ranks, see our states with the most tornadoes analysis — Texas leads the nation in raw count, and Houston is a big part of why.


Is Houston in Tornado Alley?

Not really — and that is the point. Classic Tornado Alley runs up the Plains through central and northern Texas, Oklahoma and Kansas, where dryline storms build the violent supercells that produce EF4s and EF5s. Houston sits well southeast of that corridor, in a warm, humid coastal environment that produces plenty of thunderstorms but rarely the deep, dry-air-fed rotation needed for a violent tornado. When Houston does get tornadoes, they come from two comparatively gentle sources: spring frontal storms and tropical-cyclone rain bands.

So the honest answer to “does Houston get tornadoes?” is: yes, more than almost any big city in the country — but they are the kind that break windows and peel roofs, not the kind that erase neighborhoods. The one time the metro drew a true F4, in 1992, it was through open country in eastern Harris County and no one died. You can pull the actual conditions for any Houston tornado day, back to 1970, on our historical weather lookup.


Frequently asked questions

Does Houston get tornadoes?

Yes — a lot of them. The NOAA SPC database records 430 tornadoes in the Houston metro touchdown box between 1950 and 2024, more than the Chicago (176) or St. Louis (208) metros. But they are overwhelmingly weak: 232 were F0 and only one has ever reached F4. Houston averages roughly six tornadoes a year, most of them brief and low-end.

Has Houston ever had an F5 or EF5 tornado?

No. In 74 years of records the strongest tornado in the Houston metro was a single F4 on November 21, 1992, in eastern Harris County — and it killed no one. Twelve more were rated F3. There has never been an F5 or EF5 anywhere in the metro, and the entire area has recorded just 12 tornado deaths since 1950.

When is tornado season in Houston?

Houston peaks in May (72 tornadoes in the record), the tail end of the spring severe-weather season. But it has an unusual second maximum in late summer and fall — August, October and November each carry 48 tornadoes — driven partly by landfalling tropical systems. That August bump is something almost no inland metro has.

Do hurricanes cause tornadoes in Houston?

Constantly. The two busiest tornado years in Houston history were both hurricane years: 1983, when Hurricane Alicia spun up 15 metro tornadoes in August alone, and 2017, when Hurricane Harvey produced 11. The 1961 Hurricane Carla and 2024 Hurricane Beryl added more. Landfalling tropical systems shed dozens of weak, short-lived tornadoes in their outer rain bands, which is a big reason Houston’s raw count is so high while its tornadoes stay weak.
