What steps can I take to avoid getting hit by a falling window from a skyscraper while walking about in downtown during high winds?
Here are some steps you can take to avoid getting hit by falling windows detached from tall building by strong winds from cyclones or tornadoes: 
1. The space area close to a doorway or near windows is most likely to be affected by falling items, and it is best to stay away from buildings, trees and tall electric or telephone poles. Find an open space, far away from these objects and stay low to the ground to reduce your chances of being hit by debris.
2. One of the safest places to avoid getting hit by falling objects is underground in a basement with no windows. Try to find underground spaces in downtown like the lower levels of buildings and malls, or the subway. 
3. If you absolutely need to be outside and close to tall buildings, try to stay alert and keep an eye out for falling debris. 
4. You might think that being inside a car would be a safe option, but vehicles are notoriously dangerous places to be in during high winds because of their susceptibility to being blown over or blown away or for their windows to explode.
