Bad weather

The weather over here in Edmonton has been very bad as of late. Although it's not a continuous barrage of all the worst mother nature has to offer, it has been some of the most torrential downpours I've seen. The weird thing is it appears on the horizon as a big black thunder cloud and rolls across the sky until it unleashes a flood of water from above resulting in an inch or two of rivers flowing along the side walks. I managed to capture a few seconds on my camera phone before and after.
