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 advanced across the region. Another warning covered Yellowhead County as the cell held together. Heavy rain triggered flash flooding across low-lying areas of the metro. Whitemud Drive in west Edmonton sat closed under standing water. Busy stretches of road shut down as crews pushed through blocked intersections. Travel plans collapsed across the city, with drivers sitting out the sudden downpour.
