A severe thunderstorm warning is in effect for Montreal and the Laval region.

Environment Canada meterologist André Cantin says those thunderstorms could produce heavy rain, and more.

"They can produce high winds, up to 80 or 100 kilometres per hour.  And there is a very slight risk of a tornado.  We have some reports of hail also."

Cantin says you'll hear the thunder before the lightening starts.  He cautions to take cover inside if your outdoors, and if you're driving, stop on the side of the road and put on your four way flashers.

Watches and warnings are in effect until 10 p.m.
