***Winds are 20 foot 10 minute averages             ***
***CWR: Chance of wetting rain 0.10 or greater      ***
***Ventilation Index is derived from transport wind
   multiplied by the mixing height in 100`s of ft.
   Categories are a generalized indicator and users
   are encourage to develop criteria that are
   suitable and representative of dispersion
   conditions in their local area of interest.
   Categories: low (< 200), moderate (200-500),
   high (500-700), and very high (> 700).
   -Note: Max transport winds may not occur
    at the same time as max mixing height.          ***
