Strong storms delivered a direct hit to Edmonton late Saturday, packing very large hail near the city limits. A tornado warning was issued for Stony Plain, west of Edmonton, as rotating clouds moved across the region. Another warning targeted Yellowhead County as the cell ramped up. Heavy rain sparked 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 pushed through blocked intersections. Travel plans fell apart across the city, with drivers trapped by the sudden downpour.
