|---|---|---|
| 9 | Strong Gale | 47 to 54 mph |
| 10 | Whole Gale | 55 to 63 mph |
| 11 | Storm Force | 64 to 75 mph |

Can 70 mph winds break windows?
A Design Pressure or DP rating measures the strength of a window. Standard residential windows have DP values between 15 and 50. A DP 15 window can reasonably be expected to sustain winds of roughly 77 mph before shattering. A DP 50 window is expected to sustain winds up to 173 mph.
Can you walk 70 mph wind?
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.

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 wind speed is damaging?
50-75 mph
50-75 mph – At 50+ MPH winds are officially classified as “damaging”.
What is the maximum wind speed that can cause damage?
– at 47 to 54 mph, there will be light structural damage. – at 55 to 63 mph, entire trees can be uprooted and considerable structural damage can occur. – above 64 mph, expect widespread structural damage.
How much wind is too much wind to damage my home?
45-55 mph: Structural damage is likely with winds over 45 mph, especially chimneys, shingles, and rooftop HVAC units. If you are near a beach, sea spray may affect visibility, and there will be high waves. Larger tree branches and weak limbs may break and if they are located near a structure can pose a damage risk.
What type of weather has winds over 75 mph?
For example, a hurricane is a weather system rather than a wind, and winds of75 mph (about 120 kph) or more can occur with quite a few other types of weather.Downbursts in thunderstorms, winds like chinooks (a type of foehn wind) when they are funnelled through a mountain pass, and subtropical storms can all produce winds in excess of 75mph.
What is considered a damaging wind?
Damaging winds are classified as those exceeding 50-60mph. What are straight-line winds? Straight-line winds are generally any thunderstorm wind that is not associated with rotation, and is used mainly to differentiate from tornadic winds.
