Tornado watch for Hamilton and Stoney Creek

The tornado watch was extended at 3:34 p.m. ET to cover Toronto and Hamilton. The watch now stretches across all of southwestern Ontario, from Windsor to Niagara Falls. It extends north through Barrie, Sudbury and North Bay and east through Peterborough to Renfrew, in the Ottawa Valley.

The storms could produce large hail, damaging winds, torrential downpours and frequent lightning, along with the potential for a twister, Environment Canada said.
If the tornado watch is upgraded to a warning, it means people should head to a safe location.

A warning means go to your basement — there is a tornado or you can expect that a tornado is imminent or occurring.
