Re: [TowerTalk] Wind zone maps

[Lou Laderman <lladerman@earthlink.net>]

I believe that the map shows wind speeds for each zone (3 second gust speeds 
under TIA/EIA 222 rev G). The first number is the basic speed in miles per hour 
with no ice. The number in parenthases is the basic wind speed in miles per 
hour with an ice load.
