A gale force wind or gale is a strong, persistent wind ranging from 50 km/h or 31 mph to 102 km/h or 63 mph and is typically associated with but not limited to coastal regions. According to the Beaufort Scale
Beaufort scale
The Beaufort scale /ˈboʊfərt/ is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale. The scale was devised in 1805 by Francis Beaufort (later Rear Admiral Sir Francis Beaufort), an Irish Royal Navy officer, whi…
What is considered a gale force wind?
What qualifies as gale-force winds? gale, wind that is stronger than a breeze; specifically a wind of 28–55 knots (50–102 km per hour) corresponding to force numbers 7 to 10 on the Beaufort scale. As issued by weather service forecasters, gale warnings occur when forecasted winds range from 34 to 47 knots (63 to 87 km per hour).
What damage can 40 mph winds cause?
This speed of wind makes it difficult to drive a vehicle and can blow small unsecured objects such as plastic lawn furniture around. Entire trees will be in motion. 40-45 mph: A 40-mph wind will cause a High Wind Watch by the NWS.
What is the Beaufort scale?
The Beaufort scale, officially known as the Beaufort wind force scale, is a descriptive table. It depicts the force of wind by a series of numbers from 0 to 12. Actually, the Beaufort scale goes all the way to 17, but the last five numbers only apply to tropical typhoons. These numbers are only used in the areas around China and Taiwan.
What does Gale mean in weather?
The word gale possibly originates from the Old Norse word galinn, which means “mad”, “frantic,” or “bewitched.”. Weather forecasters sometimes use the term “gale-force winds” to describe conditions that aren't quite as extreme as hurricanes or tropical storms, but probably fierce enough to snap your kite in half.
What gale force is 50 mph?
47-54 Mph 75-88 kph 41-47 knots Strong Gale Slight damage occurs to buildings, shingles are blown off of roofs. High waves (6 meters), rolling seas, dense foam, Blowing spray reduces visibility. 55-63 Mph 89-102 kph 48-55 knots Whole Gale or Storm Trees are broken or uprooted, building damage is considerable.

Why do they say gale-force winds?
The word gale possibly originates from the Old Norse word galinn, which means “mad”, “frantic,” or “bewitched.” Weather forecasters sometimes use the term “gale-force winds” to describe conditions that aren't quite as extreme as hurricanes or tropical storms, but probably fierce enough to snap your kite in half.
What is stronger than gale-force winds?
In Canada, maritime winds forecast to be in the range of 6 to 7 are designated as "strong"; 8 to 9 "gale force"; 10 to 11 "storm force"; 12 "hurricane force".
Can you walk in 60 mph winds?
Attempting to walk in 60-70mph winds is dangerous, and there is a high risk of being blown over and suffering injury. Stay away from difficult underfoot conditions or exposed edges and get off the hill as soon as possible. You're having a laugh!
How much force does 70 mph wind have?
12.5 psfWind Speed Conversion (MPH) Ie: if the wind speed is 70 mph, the wind pressure is 0.00256 x 702 = 12.5 psf.
Can planes fly in gale-force winds?
In summary, it's perfectly safe to fly in strong wind. The aircraft can handle it, and the pilots are well trained to do so. Just expect it to be a little bumpy during take-off and landing. But, there is nothing to be scared of.
What is the difference between strong winds and gales?
A gale is a strong wind; the word is typically used as a descriptor in nautical contexts. The U.S. National Weather Service defines a gale as sustained surface winds moving at a speed of between 34 and 47 knots (63–87 km/h, 17.5–24.2 m/s or 39–54 miles/hour) of.
What does a gale warning look like?
There is a daytime and a nighttime display signal for gale-force winds, and these visual alerts are triggered on the coastline when winds blow between 39-46mph over ten-minute periods. The daytime visual signal for a gale warning is two red pennants, and the nighttime signal is both white and red lights.
How windy is too windy?
"High wind" with sustained speeds of 40 to 57 mph. Wind conditions consistent with a high wind warning. "A Moderate Threat to Life and Property from High Wind." "Very windy" with sustained speeds of 26 to 39 mph, or frequent wind gusts of 35 to 57 mph.
What damage can 70 mph winds cause?
Winds 64-75 MPH: Wind damage is widespread, with risk to large trees being blown over. Winds over 75 MPH: Hurricane force winds, sever damage will occur. Damaging wind can harm roofs and windows. Trees will be uprooted along with risk of overturned small mobile homes.
How much wind can an RV withstand?
Winds as low as 10 miles per hour can affect a moving RV, making it hazardous to drive. When parked, most RVs can withstand winds up to 75 mph (120 km/h) without tipping over.
Is 60 mph winds alot?
Damaging winds are classified as those exceeding 50-60 mph.
How do you calculate wind force?
Armed with pressure and drag data, you can find the wind load using the following formula: force = area x pressure x Cd. Using the example of a flat section of a structure, the area – or length x width – can be set to 1 square foot, resulting in a wind load of 1 x 25.6 x 2 = 51.2 psf for a 100-mph wind.
Is wind a force?
Wind is the movement of air relative to the Earth's surface. As with all moving things, it is caused by a force acting on it. Force is a pull or push that changes the resting state, motion, or direction of an object.
What wind speed will lift a human?
An average person could be moved by a 67 mph wind, and an average car can be moved by a 90 mph wind. Isn't it great how math can help us with so many questions?
What is a gale?
v. t. e. A gale is a strong wind, typically used as a descriptor in nautical contexts. The U.S. National Weather Service defines a gale as 34–47 knots ( 63–87 km/h, 17.5–24.2 m/s or 39–54 miles/hour) of sustained surface winds. Forecasters typically issue gale warnings when winds of this strength are expected.
What is a gale warning?
In the United States, a gale warning is specifically a maritime warning; the land-based equivalent in National Weather Service warning products is a wind advisory . Other sources use minima as low as 28 knots (52 km/h; 14 m/s; 32 mph), and maxima as high as 90 knots (170 km/h; 46 m/s; 100 mph).
Where does the word "gale" come from?
The word gale is derived from the Middle English gale, a general word for wind of any strength, even a breeze. This word is probably of North Germanic origin, related to Icelandic gola (breeze) and Danish gal (furious, mad), which are both from Old Norse gala (to sing), from Proto-Germanic * galaną (to roop, sing, charm), from Proto-Indo-European * gʰel - (to shout, scream, charm away). One online etymology website suggests that the word gale is derived from an earlier spelling, gail, which it claims is of uncertain origin.
