I previously analyzed the wind directions for the 5 days after the tragedy. The wind direction was changing from NW to SE to S to N. I described the wind as traveling in a circular motion. This map depicts the areas affected. Notice Canada is affected all the way up to Sudbury, Ontario and through Lake Ontario area and St. Lawrence river valley. Pittsburgh got completely nailed by this.
