Winds of 15 to 25 mph are deemed "breezy," while winds of more than 25 mph are termed "windy," according to the National Weather Service. Microclimates are another issue with wind predictions in southern Idaho. The area experiences hot, dry conditions with little precipitation, so areas near roads or underdeveloped land may have stronger winds than others located a distance away.
The American Red Cross recommends that you assume that every storm will be a tornado if you're in an urban area with few trees and high buildings.
"Breezy" is defined as a sustained wind speed of 15–25 mph, while "Windy" is defined as a sustained wind speed of 20–30 mph. What causes a highly windy day? Winds of 30 to 40 mph over an extended period of time. These winds can cause damage to buildings, vehicles, and vegetation. They can also be fatal to unprotected humans. The strongest wind event on record in the U.S. was the Great Kansas City Tornado of 1974. This tornado killed 157 people and injured more than 600 others.
When hurricanes hit land, they can produce high winds that can exceed 100 miles per hour. However, only very few hurricanes make it into the water instead. Hurricanes are tropical storms with winds of at least 74 miles per hour that travel across or near the coast. There are eight categories of hurricanes, with Category 4 being the most severe. Hurricane Katrina was a Category 5 storm when it struck Louisiana in 2005. It was the most powerful hurricane to strike the United States since Galveston Island, Texas was destroyed by a hurricane in 1900.
Tornadoes are violent winds associated with thunderstorms that reach up to 500 miles per hour. They can tear roofs off houses, flatten trees, and destroy entire neighborhoods. Tornadoes usually occur in clusters and have common origins: They develop in the same areas of low pressure that bring moisture to ground level.
Wind speeds of 21 to 25 mph with periodic gusts of 30 to 35 mph. "High Wind poses a very low risk to life and property." Conditions ranging from "breezy" to "windy." Wind speeds are approximately 20 mph with regular gusts of 25 to 30 mph. No significant weather concerns.
Gusts can reach 70 mph in hurricanes or other powerful storms. But even at those levels, most people can safely seek shelter ahead of the storm. The only real danger is when these high winds come as a surprise -- like when a tornado strikes.
An average wind speed of this magnitude and frequency would blow trees into the path of the wind and cause widespread damage to buildings, but not much else. There are reports of large waves being created by these winds, but they're usually associated with storms or tsunamis that have larger causes than just wind blowing against water. Waves this size likely indicate that a tsunami has been triggered by an underwater landslide or rock slide.
These estimates were made based on data collected during Hurricane Sandy in October 2012. Because hurricanes are rare events, it's difficult to estimate their effects without first-hand experience. However, with information like this one from the National Weather Service, scientists can make an estimate based on past behavior and extrapolate what might happen with future storms.
I'm guessing "wind" refers to a certain direction: A chilly north wind swept over the grassland. "Winds" suggests a change in direction, thus "winds of up to 60 miles per hour" would arrive from several directions, most likely as gusts—sudden, rapid bursts of moving air.
Now, I know this isn't technically correct because "wind" is singular and therefore should be "windle." But you know what they say about assumptions...
Anyways, here's where my assumption gets me: If "wind" is singular, then why does its plural form appear so often? The answer is simple: Convenience. It's easier to write "the winds" than "one wind" or "two winds." That's why we usually see "winds" instead of "a wind" or "two winds."
But what if we wanted to be precise? Well, we could always use "a wind" or even just "wind" itself. For example: "Show me the winds." or "Blow on a windchime." These sentences are saying that you should show or blow in a particular direction, not that there are multiple directions (like with "winds").
So, while "winds" can refer to one single direction, it's more commonly used to describe multiple directions.
"Windy" is defined as a sustained wind speed of 20–30 mph. Milder winds are called "gusty."
The word "windy" comes from the old English wīn, meaning "air or breath," and diē, meaning "day"; thus, "windy day" means a day with clear air and no clouds in the sky.
The exact speed at which it becomes "windy" varies depending on the location. In general, wind speeds increase as you go higher up in altitude. Thus, windy conditions can be found at many locations around the world at all times of the year, but they are most common during thunderstorms, cyclones, and hurricanes.
In terms of average wind speeds, there are only two places on Earth where it is possible to find windy conditions all the time: Antarctica and the Atacama Desert. Both places have very low humidity and no precipitation to cause any turbulence.
On average, wind speeds increase with height above ground level (AGL) until they reach a maximum value at about 300-500 feet AGL. From there on downward, wind speeds decrease with increasing altitude.
