8-12 Mph 12-19 kph 7-10 knots Gentle Breeze Leaves and small twigs move, light weight flags extend. Large wavelets, crests start to break, some whitecaps. 13-18 Mph 20-28 kph 11-16 knots Moderate Breeze Small branches move, raises dust, leaves and paper.
"Breezy" to "Windy" conditions. Sustained wind speeds around 20 mph, or frequent gusts of 25 to 30 mph. " No Discernable Threat to Life and Property from High Wind." Note: In "High Wind" conditions, small branches break off trees and loose objects are blown about.
An average person could be moved by a 67 mph wind, and an average car can be moved by a 90 mph wind.
Breezy is described as a sustained wind speed from 15-25 mph. Windy is a sustained wind speed from 20-30 mph. Sustained winds between 30-40 mph.
Now, assuming a coefficient of friction of = 0.75, would be 36.9 degrees, air density of 1.25 kg/cu. m, and an exposed area of 1.5 sq. m, you get an approximate minimum velocity to pick up the 100 lb person as 16.9 m/s, or, 60.73 kmph or, 37.8 mph.
Breezy is described as a sustained wind speed from 15-25 mph. Windy is a sustained wind speed from 20-30 mph. What makes a very windy day? Sustained winds between 30-40 mph.
I guess the wind speed would need to be between 80 mph - 200 mph or more. It depends on the surface area exposed, the weight of the car and it's wheel track. Greater the wheel track, and the weight, harder to overturn it. Empty vans are the easiest to flip over because of the low weight and large surface area.
Hypercane Cara was third named storm, second major hurricane, and the first hypercane of the 2776 Atlantic hurricane season. The third storm of the season, Hypercane Cara developed out of a weak low pressure system which migrated across the Atlantic and over an erupting underwater volcano.
The answer obviously depends on the size of your boat and the size of the waves but in general, wind speeds over 20 knots (23 mph) are too windy for boating. At this wind speed, almost all size boats will be greatly affected, and smaller boats may even be in danger of capsizing.

If a recipe calls for 2 large eggs you can use 3 medium eggs instead if you prefer.
