Severe Thunderstorm Warning

A line of severe thunderstorms along a slowly advancing cold front is moving across eastern Ontario and into southwestern Quebec. A severe thunderstorm warning has been issued for Valleyfield, Huntingdon and the western off island suburbs of Montreal until 9:30pm. The storms produced 60km/h winds in Ottawa with higher gusts and dropped the temperature from 30C down to 21C. They will approach the city in the next hour or so.

The watch remains in effect until 1am for the entire region and has been extended south into northern New York and Vermont.
