That’s less than the five to 10 centimeters the weather service had previously predicted for Wednesday. Environment Canada warned in a weather warning that snow is expected to fall during typical morning commute times, “when temperatures will be below freezing, creating hazardous driving conditions.” “Bad weather can contribute to transport delays. Prepare for rapidly changing and deteriorating travel conditions. Slow down when driving in slippery conditions. Watch for taillights ahead and maintain a safe following distance. Visibility can drop suddenly at times in heavy snowfall.”
