You’re sitting in a coffee shop in Tacoma or maybe hiking a trail near Spokane when the sky turns a weird, bruised shade of purple. Most Washingtonians wouldn’t even think the word "tornado." We think about rain. We think about gray marathons of drizzle. But twisters? That’s a Kansas thing.
Except it isn’t.
Honestly, tornadoes in Washington state are more common than you’ve been led to believe. We aren't talking about The Wizard of Oz sweeping through the Palouse every Tuesday, but the data is there. The state averages about two to three tornadoes every single year. Sometimes we go a year with zero; sometimes, like in 1997, we get four in a single day.
The "It Doesn't Happen Here" Myth
People love to say the mountains protect us. Or the cool Pacific air kills the rotation. While there's some truth to the meteorology of "stable air," the geography of Washington actually creates its own weird pockets of danger.
Take the Olympic Mountain Velocity Shear Zone. It’s a mouthful, but basically, when wind hits the Olympics, it has to go somewhere. It gets forced around the peaks and starts spinning in the lowlands. This is exactly what happened in December 2018.
Most of us remember the Port Orchard tornado. It was an EF2. It stayed on the ground for five minutes and chewed through about 250 homes. Before that hit, if you’d asked anyone in Kitsap County if they were worried about a tornado in December—December!—they would’ve laughed at you.
Nature doesn't really care about our "it doesn't happen here" vibes.
When the PNW Gets Deadly
We have to talk about Vancouver. Not the Canadian one. Vancouver, Washington, holds the grim title for the deadliest tornado in Pacific Northwest history.
On April 5, 1972, an F3 tornado slammed into the city. It didn't look like a classic funnel. Witnesses described it as a "black wind cloud" or just a wall of debris. It hopped the Columbia River from Oregon and tore through an elementary school, a bowling alley, and a grocery store.
Six people died. Hundreds were injured.
The terrifying part? There was no warning. No sirens. No push notifications on phones back then. Just a sudden roar that sounded like a freight train—the classic signature of a monster.
Why Our Tornadoes are Different
Tornadoes in Washington state usually fall into two categories:

- The Landspouts: These are the "diet" version of a tornado. They don't come from a big, rotating thunderstorm (a supercell). Instead, they’re just spin-ups that happen when the wind at the ground is doing something different than the wind just above it. They look scary, but they usually just knock over a few fences or some unlucky pine trees.
- The Cold Core Twisters: These are the ones that catch us off guard. They happen in the spring or late fall when a blast of cold air from the Pacific hits the relatively "warm" land. They are small, shallow, and move fast.
The problem is our radar.
In the Midwest, the land is flat as a pancake. Radars can see everything. In Washington, we have these giant things called the Cascades. They block radar beams. A small tornado can form under the radar's "eyesight," touch down, wreck a barn, and disappear before the National Weather Service even sees a blip.
Spotting the Signs (When Radar Fails)
Since we can't always rely on a 20-minute head start from a siren, you've gotta know what to look for.
- The Green Sky: It sounds like folklore, but it’s real. Deep moisture and light scattering in heavy clouds can make the sky look sickly green.
- The Roar: It’s not a whistle. It’s a low-frequency rumble that vibrates in your chest.
- Large Hail: If you see golf-ball-sized hail in Washington, get inside. That kind of energy in the atmosphere is rare here, and it usually means something nasty is brewing.
- Rotating Debris: Sometimes the "funnel" is invisible because the air is too dry or the cloud base is too high. If you see a "dust devil" that looks like it’s on steroids and lifting heavy objects, that’s a tornado.
Real Talk: Is Your House Ready?
Washington building codes are great for earthquakes. They aren't always great for 130 mph winds. Most of our homes are built to withstand heavy snow loads or "straight-line" wind gusts, but a direct hit from an EF2 is a different story.
You don't need a storm cellar. That’s overkill.
But you do need a plan. If a warning actually pops up on your phone—and yes, the NWS does issue them here—don't go to the window to take a TikTok. Go to the basement. If you don't have a basement (typical PNW), find the smallest room in the middle of the house. The bathroom is usually your best bet because the plumbing pipes help anchor the walls.

What to Do Next
Don't panic, but stop assuming we're immune.
First, check your insurance. Most standard Washington homeowners' policies cover wind damage, which includes tornadoes, but it’s worth a five-minute phone call to confirm you don't have a weird "named storm" exclusion.
Second, get a NOAA Weather Radio. Our cell towers can get wonky during big wind events. A battery-powered radio is the only way to get official info when the grid goes dark.
Lastly, identify your "safe spot" today. Don't wait until the sky turns purple and the trees start snapping. Pick the interior closet or bathroom now. Put a pair of sturdy shoes in there. Most tornado injuries aren't from the wind—they’re from people walking barefoot on broken glass after the storm passes.
Washington is beautiful, but it’s moody. Sometimes that mood involves a vortex.
