How strong does wind have to be to pick up a person?

Knocking you down would take a wind of at least 70 mph. The terminal velocity, which is the wind speed (falling speed) where the force of the wind equals the force of gravity, for a person is about 120 mph — that would likely knock you down.

Can wind pick you up?

But high wind can definitely pick up a person. In fact, if you were standing in the parking lot, the wind wouldn’t just pick you up—it would also peel the pavement from the ground!

Can 70 mph winds break windows?

The simple answer is yes. Hurricanes can produce extremely dangerous winds. A Category 5 storm can generate wind speeds of over 200 miles per hour. While steady wind may be unlikely to shatter a window, sudden, sharp gusts can add immense pressure to windows and doors and can break them.

Is 80 mph wind bad?

Most thunderstorm winds that cause damage at the ground are a result of outflow generated by a thunderstorm downdraft. Damaging winds are classified as those exceeding 50-60 mph. Even anchored mobile homes can be seriously damaged when winds gust over 80 mph.
