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 moved across the region. Another warning covered Yellowhead County as the cell kept its strength. Heavy rain sparked flash flooding across low-lying areas of the metro. Whitemud Drive in west Edmonton ended up closed under standing water. Busy stretches of road shut down as crews responded to blocked intersections. Travel plans fell apart across the city, with drivers slogging through the sudden downpour.
