Hurricane vs. Tornado: What's the Difference?

Both are spinning windstorms, but they differ enormously in size, origin, and lifespan. A hurricane is vast — hundreds of kilometres across — forms over warm tropical oceans, and can last for days. A tornado is tiny by comparison — often under a kilometre wide — forms over land from a thunderstorm, and lasts only minutes, though its winds can be even faster than a hurricane's. In short: hurricanes are huge, slow, and ocean-born; tornadoes are small, brief, and land-born.

Which should you use?

Hurricane

It's a hurricane when the storm is huge, sea-born, and tracked for days — bringing wind, rain, flooding, and storm surge over a wide area.

Tornado

It's a tornado when it's a narrow, violent funnel from a thunderstorm, striking a small area for a few minutes with the fastest winds on Earth.

Frequently asked questions

Which is more powerful, a hurricane or a tornado?

It depends how you measure. A hurricane releases vastly more total energy and affects a huge area. But a tornado packs the fastest winds on Earth in a tiny, concentrated path.

Can a hurricane cause tornadoes?

Yes. Hurricanes often spawn tornadoes in their outer rain bands when they make landfall, adding a second hazard to the storm.

Why do hurricanes last longer than tornadoes?

A hurricane is continuously fed by heat and moisture from a warm ocean, sustaining it for days. A tornado depends on a single thunderstorm's updraft, which lasts only minutes.
