The wind direction must be such that the fallout will be in a favorable sector. 3. In order for the wind condition to be satisfactory, surface winds and all resultant winds from surface to 2000 feet should lie within the favorable sector. 4. Favorable winds for forecasting a shot day shall be from 180ø to 270ø. 5. Favorable winds for a shot shall be from 150ø to 330ø. 6. Wind velocity shall never be less than 5 miles per hour and normally not greater than 20 miles per hour for favorable conditions, both on forecast and on the actual shot procedure. 7.
