A band of severe weather rolled across southern Ontario Monday, making for a noisy night and causing street flooding in the London area.

Several tornado warnings were issued because of the storms, and although there were no confirmed strikes, at least one possible twister was spotted by a storm chase near Goderich on the Lake Huron shoreline.

There were no reports of damage from police or fire officials.

London police say some roads were closed due to heavy rainfall. Newbold Drive between Adelaide Street South and Bessemer Road as well as Florence Street between Kellogg Lane and Eleanor Street were temporarily closed for clean up.

Environment Canada is reporting 47.8 millimetres of rainfaill at the London airport overnight and 48.5 at the airport Sarnia.

The forecaster says peak winds were near 80 km/h in many areas, with a speed of 96 km/h reported at the airport in Chatham-Kent.

In Toronto, GO Transit says its 6:25 a.m. train from Richmond Hill to Union Station in Toronto had to be cancelled due to flooded tracks.

Lightning caused some damage in Port Elgin, where Karen Devaul said a lightning bolt hit her clothesline at about 9 p.m., and entered the home, causing a bathroom wall to cave in. There were no injuries.
