What were the weather conditions like when the Delta Airlines plane crashed at Toronto Pearson International Airport?

The weather conditions were severe at the time of the crash, with winds of about 40 miles per hour, a minus 2 degree wind chill, and actively blowing snow. Visibility was limited as snow continued to blow through the air. The area had experienced more snow between Thursday and Sunday than they saw all of last year, creating challenging conditions for aircraft operations. These harsh winter weather conditions are being examined as a potential contributing factor to the crash.
