The Dangers of Strong Winds:

A moderately strong wind can provide a good workout, if you're walking against it; the extra effort required can be comparable to trudging through deep snow! However, the stronger the wind becomes, the more unpleasant and dangerous it is to be in. Strong winds can kick up dirt and debris, which can potentially lead to injury if it hits someone. In addition, winds that are strong enough even have the ability to topple down trees and power lines - and this isn't taking hurricanes and tornadoes into consideration!

A rather inconvenient secondary effect of strong winds is that they often render umbrellas unusable, so if heavy precipitation is present, strong winds can make conditions far more unpleasant.

Another thing to consider is that if you are walking against the wind, the wind blowing in your face may force you to keep your head lowered; this poses a danger as it can reduce visibility. This reduction in visibility can have consequences of varying severity, from being unable to enjoy the scenary, to tripping over a curb, to being unable to spot a car when crossing the road.

Lastly, it is inadvisable to go for a walk where there is a hurricane or a tornado in the area, unless it is to evacuate said area. 

When Strong Winds are Most Likely to Occur:

Strong winds are most likely to occur when:

• A low pressure system is in the area.
• A cold front is moving over the area.
• There is a thunderstorm (which can come with tornadoes).
• There is a large difference in air pressure (due to winds traveling from high to low pressure); this is most commonly seen in the form of land/sea breezes. 

From the Beaufort Scale, once winds reach about 38-49 km/h (corresponding to a wind force of 6), large tree branches start to move and it becomes difficult to use umbrellas. A wind force of 7 (50-61 km/h wind speed) indicates whole trees starting to move, and at a wind force of 8 (62-74 km/h) twigs break off trees, becoming a serious hazard. Walking outside when wind speeds are greater than 74 km/h is inadvisable due to the risk of being hit by flying debris.
