What Is Classified As A Strong Wind?

How do you classify wind speed?

In order of increasing wind speed from less than 1 kilometer per hour (less than 1 mph) to more than 120 kph (75 mph), these are (0) “calm”; (1) “light air”; (2) “light breeze”; (3) “gentle breeze”; (4) “moderate breeze”; (5) “fresh breeze”; (6) “strong breeze”; (7) “moderate gale” or “near gale”; (8) “fresh gale” or ….

What speed wind is dangerous?

Damaging winds are classified as those exceeding 50-60 mph. Are damaging winds really a big deal? Damage from severe thunderstorm winds account for half of all severe reports in the lower 48 states and is more common than damage from tornadoes.

Where is the windiest place on Earth?

east AntarcticaFrom February 1912 to December 1913, scientists measured the wind speed at Cape Denison, a rocky point at the head of Commonwealth Bay in east Antarctica. To this day it is recognised as the windiest sea level station on Earth. The windiest hour was recorded on 6 July 1913 at 95mph (153km/h).

Note: In “High Wind” conditions, small branches break off trees and loose objects are blown about.

What is normal wind speed?

In the U.S., daily wind speeds typically average between 6 and 12 miles per hour (10 and 19 kilometers per hour) throughout the course of a year. These averages vary widely by geographic location.

Is 16mph wind strong?

The 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 30 mph winds do?

A Wind Advisory means that sustained winds of 30 mph for one hour and/or frequent gusts of at least 45 mph are occurring or expected within the next 36 hours. These winds will make it difficult to drive high profile vehicles. … Winds this strong may damage trees, power lines and small structures.

What can 50 mph winds do?

50 mph: Raindrops flying at this velocity will start to hurt and bending down is required to stay in balance. This wind speed is capable of blowing down large trees. 70 mph: This is around maximum wind speed most humans can withstand without getting blown away.

Can 20 mph winds cause damage?

No! “Can 20 mph winds cause damage — Damaging winds are classified as those exceeding 50-60 mph. … Wind speeds can reach up to 100 mph and can produce a damage path extending for hundreds of miles.”

What is the fastest wind in the universe?

Astronomers have discovered the fastest ultraviolet winds ever recorded in the Universe, swirling around a supermassive black hole at speeds of up to 200 million km/h (125 million mph). “We’re talking wind speeds of 20 percent the speed of light,” says one of the team, Jesse Rogerson from York University in Canada.

Can you walk in 30 mph winds?

Walking in a 30 mph wind can be tricky, at 40 mph you could be blown off balance and at 60 mph it is almost impossible to walk. The wind speed given by the BBC or local radio station will be at sea level. It increases as you increase in height.

At what wind speed is it dangerous to drive?

30 to 45 mphWinds of even 30 to 45 mph can make driving significantly more dangerous. First, they can actually blow your car off course. Second, they can blow other vehicles, including big tractor-trailers, off course, posing significant danger to other motorists on the road.

What damage can 45 mph winds?

According to the National Weather Service, slight damage can begin when winds reach 45 mph, but this range is considered “non-severe”. These non-severe winds may cause some tree branches to break off and can cause damage to already loose or susceptible shingles.
