A severe thunderstorm warning has been issued for the Montreal area.
The warning affects Chateauguay-La Prairie, Laval, Longueuil-Varennes and the Montreal island region.
Environment Canada warned of very strong winds and ping pong ball sized hail, as well as heavy rain.
Officials warned those in the area to stay indoors.
A tornado warning was also issued for western Quebec, with Papineauville singled out as being particularly at risk.
The warning comes as the Montreal area was already under a heat warning, which could last until midweek.
