Severe Thunderstorms

9:30pm Update: Storms are now moving just south of L'Ile Perrot with rain finally falling on my parched lawn and flowers. Lots of lightning, but no severe weather. Storms are heading for Chateauguay and Mercier.

A line of fast moving thunderstorms crossed the island of Montreal around 4pm today producing flash flooding in some suburbs and toppling trees and power poles in others. The storms caused flooding and wind damage through the center of the city with major flooding at Victoria and Jean Talon (above from CJAD.com), and power poles knocked down in South Shore Brossard. Trees also fell in may areas including several onto cars and one onto a home in Cote St. Paul where several families had to be evacuated. Despite the flooding in parts of the city, others such as here in Dorion had no rain at all. The temperature under sunny and humid skies had reached 30C but rapidly dropped to 22C during the storms.

Another line of storms is splitting the area at this hour, with cells passing west of my location across Valleyfield as well as more storms across the center portion of the city. I don't have an estimate on rainfall as of this time from the afternoon storms, and my gauge here at the house was bone dry.
