Wind speed between 5 and 7 mph (8-11 km / h). You can feel the wind in your face. 4 RCW: strong wind. Wind speed between 7-10 MPH (11-16 km / h).
1 - Light breeze, 2 mph breeze 3 - Light breeze, 812 mph. Twigs and small branches will shift. 4 - Light breeze, 1318 mph.
A wind of 20 km / h is quite normal. In most of the world, winds at this speed will be common. Common sense would dictate that most things were seated outside and had to stay where they are, built or anchored to easily withstand 20 mph winds.
at 19-24 mph the small trees begin to sway. at 25-80 mph, the big branches move, creaking in the wires, and using an umbrella becomes difficult, if not impossible. at 32-38 miles per hour entire trees will be in motion.

Strong ground winds - 20 MPH or more - can make takeoff bumpy, but only for a minute or two.

The National Weather Service defines wind and wind differently, winds of 15 to 40 miles per hour are considered wind and over 25 miles per hour as wind. The other challenge with the wind forecast is the microclimates we have in southern Idaho.
Facts about the wind Walking in wind speeds of 30 km / h can be difficult, at 40 km / h you can lose balance and at 60 mph it is almost impossible to run.
At 20 km / h the trees begin to sway and the leaves can move. ■■■■ branches can fall at 30 km / h.
A basic nautical rule for estimating wind speed is that at around 35 mph it becomes difficult to see the wind.
A storm is a strong wind that is often used as a description in a nautical context. The U.S. National Weather Service defines a storm of 34 to 47 knots (63 to 87 km / h, 17.5 to 24.2 m / s, or 39 to 54 mph) with sustained surface winds. Weather forecasts usually give storm warnings when winds of this strength are expected.
40 km / h: Umbrella use becomes difficult, creaks can be heard through wires and branches. 32 km / h: Whole trees sway and it becomes difficult to walk in the wind. 39 km / h: Branches can be broken by trees, cars can turn on the road. 47 mph: minor structural damage.
Wind information page. A wind warning means sustained winds of 30mph and / or frequent gusts of at least 75mph are occurring or are predicted for one hour within the next 36 hours. This wind makes it difficult to drive large cars. This strong wind can damage trees, power lines and small structures.
(Don’t confuse gusts and gusts). Gusts of 30 knots can be dangerous in the last part of a landing approach. The most dangerous gust is a sudden tail wind. For example, suppose an aircraft flies in the landing configuration at approximately 1.3 times its stall speed, a fairly normal final approach speed.
For example, if the average wind speed is 25 knots, it is normal for gusts of 35 knots and lighter gusts to occur. Thunderstorms and downpours can bring with them even stronger gusts of wind. Wind speed and direction can be significantly affected by the local environment.
