A line of powerful thunderstorms has left parts of Toronto without power, and the rest very, very wet. Toronto Hydro says approximately 4,400 people are currently without electricity, most of them west of Bathurst, south of Lawrence, east of Caledonia Park Rd.

Skies began to darken shortly before 7:00 as a line of storms moved southeast through the city. Monsoon-like rain coupled with high winds and frequent lightning persisted for a little over half an hour and there were reports of localized flooding on the Don Valley Parkway and Lake Shore Blvd. Weather experts warned of possible wind damage and poor driving conditions.

Samuel Aguiar sent this time lapse of the storm approaching.

Last a year storm very much like this one caused widespread flooding and power outages across the GTA. The ensuing chaos crippled the TTC and left a GO train stranded amid rising flood waters in the Don Valley.

Environment Canada has now cancelled its severe thunderstorm warning for the City of Toronto.

Here are pictures of the storm on social media.
