Dust storm means a situation where sustained high winds have caused fugitive dust emissions in and around the Tri-Cities area and the wind speed exceeds 20 miles per hour (averaged on the quarter hour over the previous 2 hours). The recorded wind speed will be taken as the average of the measurements from the five BCAA meteorological stations, which are part of the Public Agricultural Weather System (PAWS).
