NC High Winds in Mountain Regions

NC High Winds in Mountain Regions

NC High Winds in Mountain Regions

(OP)
This is mainly directed to North Carolina

Does anyone have a better explanation  of the basic wind velocities for the mountain regions

 In the IBC code used in NC, It states that wind velocities are to apply to all mountain tops, crests, knobs or peaks as named on the USGS Quadrangle maps.

Moreover, goes on to say

Effect of the 130 mph wind is to extend downward from the crest for 200 ft or to the controlling elevation for a 120 mph wind, whichever is lesser

To me this is confusing.

Looking for some input.

RE: NC High Winds in Mountain Regions

I have designed structures in the mountains here. I find if you look at IBC and speak with local code officials to see what they recommend as far as wind speeds go. This works well for me. Good luck.
