DEMONSTRATION OF A WEATHER FORECASTING SERVICE

Based on an earlier report (ABTR/RD/TM91-04), the department acquired the service of a private forecasting company called World Weatherwatch (WWW) of Ontario to monitor and predict winter weather conditions for the Edson district maintenance staff. The demonstration began on January of 1992 and finished during March of 1992 at a cost of $1,500. For the two and a half months of service, the vendor's meteorologists analyzed the current weather conditions over the different areas that make up the Edson district, and verbally recorded the conditions, trends, and impending storm events onto an AGT voice box. The area foremen from the seven maintenance shops were asked to call up the voice box and find out what their local conditions and forecasts were like. The accuracy of the service was determined by comparing the forecasts to actual conditions as reported by the foremen, and by comparing them to the public Environment Canada broadcasts on local radio stations. The results were mixed, but generally, WWW's forecasts failed to predict the amount of precitipation for several severe storm days consistently at all seven maintenance beat areas. Sometimes, WWW's forecasts were very close, and at other times and places, they were completely off the mark. The majority of the foremen refrained from using the service because of inconsistencies. This scaled-down experiment of a fully computerized Road Weather Information System (RWIS) is not necessarily indicative of the potential usefulness and savings a RWIS could provide. (A)
