A tornado watch for Waterloo Region and Wellington County has ended.

Meteorologists were following a line of severe thunderstorms just north of the region, stretching from Goderich to Barrie. The storm system is capable of producing very strong winds, heavy rain, and hail the size of ping pong balls.

Environment Canada had issued tornado warnings for several communities in the area as a line of severe thunderstorms with embedded tornadoes moved into the Lake Simcoe region from the U.S. midwest Tuesday afternoon.

That system caused two tornadoes and left one child dead in Nebraska.

Four people were struck by lightning on a Toronto golf course earlier Tuesday.
