Possible tornado damage in Grand Bend

CTV Kitchener: Grand Bend storm A possible tornado in Grand Bend Sunday night. Krista Simpson has more.

Strong thunderstorms, heavy rain and possible tornadoes crossed southwestern Ontario Sunday evening, leaving trees and hydro lines down.

Environment Canada may send a team to the Grand Bend area today to try to confirm whether  a tornado touched down there.

Ontario was hit by severe thunderstorms last night that stretched all the way from Windsor to Kingston.

There is an unconfirmed report of a tornado in Grand Bend, along the shores of Lake Huron, and funnel cloud sightings were also reported in some other locations such as Millbank.

Some trees came down, there were power outages in parts of southwestern and central Ontario, and some localized flooding occurred north of Toronto.

Thousands of customers in the Grand Bend area and to the east remained without power Monday morning.  Hydro One said it may be as late as 6 pm before all power has been restored.

Shortly before 10:00 Monday morning Lambton County OPP updated the situation.

"All of the main roads are open and most of the side streets are passable.  Beach O’Pines appears to be the area most affected by the storm and some streets in that area are not yet open.

OPP officers continue to patrol the area and to direct traffic as required while the clean-up continues.  Motorists are asked to please exercise caution when travelling through the area as traffic slow-downs and intermittent closures may be encountered while the clean-up process progresses.

The Grand Bend Legion is open for regular business hours today and is available for anyone who is in need of shelter."
