Strong storms delivered a direct hit to Edmonton late Saturday, pushing very large hail near the city limits. A tornado warning was issued for Stony Plain, west of Edmonton, as rotating clouds tracked across the region. A second warning covered Yellowhead County as the cell held together. Heavy rain caused flash flooding across low-lying areas of the metro. Whitemud Drive in west Edmonton was left closed under standing water. Key routes shut down as crews rushed to blocked intersections. Travel plans fell apart across the city, with drivers slogging through the sudden downpour.
