While considering the macro-scale variation in wind speed, you would do well to
not overlook the highly localized orographic effects on wind speed and
associated damage. The effect of local topology on wind speed is sufficiently
strong and well-understood to drive zoning regulations:

In the Northern Hemisphere, Typhoons rotate in a Counter Clockwise Direction,
so the actual wind on the ground has to be factored with the speed of travel of
the typhoon itself. The faster the speed over ground of the typhoon, the more
wind that will be added or subtracted over the ground depending on what
position within the circulation a specific point is.

This is why the northeast quadrant of typhoons (which typically move northwest)
in the Philippines are considered the "strong side". For example check out this
news article containing a quote from NASA:
http://www.philstar.com/nation/2013/11/08/1254420/yolandas-strongest-side-may-hit-manila-nasa
"US-based National Aeronautics and Space Administration (NASA) warned
that Manila may receive a lashing from super typhoon Yolanda's strongest side,
its northeastern quadrant."
