***Thunderstorms imply strong gusty winds***

***Winds are 20 foot 10 minute averages***

***CWR-chance of wetting rain 0.10 or greater***

***Ventilation Index is derived from the

   transport wind multiplied by the mixing

   height in 100's of feet. Index 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.***

     Note: Max transport winds may not occur 

     at the same time as max mixing height.
