Can planes take off in 50 mph winds?
There is no headwind limitation for most commercial aircraft for take off, and therefore is no maximum overall limit for take off (or landing). If there was a 100mph wind, all of which was a headwind component, in theory the aircraft wouldn’t be restricted from taking off.
What can 65 mph winds do?
Strong Gale (47-54 mph) – Minor structural damage may occur (shingles blown off roofs). Storm (55-63 mph) – Trees uprooted, structural damage likely. Strong Storm (64-73 mph) – Widespread damage to structures.

25 mphThe National Weather Service defines “breezy” and “windy” differently, winds 15 to 25 mph are considered “breezy” and above 25 mph are considered “windy.” The other challenge we run into with wind forecasts are the micro-climates we have across southern Idaho.
What can 50 mph winds move?
Heading toward 50 mph, shingles can tear off roofs, Elsner said, and eaves can lift and blow away, “especially on weaker structures like sunrooms.”
What wind speeds are dangerous?
sustained speeds of 40 to 57 mph with gusts greater than 58 mph. Damaging wind conditions are consistent with a high wind warning. “A High Threat to Life and Property from High Wind.”
