High heat and humidity have dominated much of Quebec and Atlantic Canada over the last couple of days with some places setting new record daytime highs.

Parts of northern Quebec also reached official heat wave status Monday after three consecutive days with temperatures of 30°C or higher.

The heat will continue to grip the region on Wednesday with a widespread thunderstorm threat expected as well.

"Conditions are favourable for the development of severe thunderstorms that may be capable of producing strong winds gusts, large hail and heavy rain this afternoon and evening," warns Environment Canada in a severe thunderstorm watch issued for New Brunswick early Wednesday.

It will be a similar story for much of southern Quebec with "damaging wind gusts and torrential rain" being the greatest threats.

Drivers are being warned to prepare for fast moving water on roads as well as rapidly rising rivers that can "sweep away bridges, culverts, buildings, and people."

"Very strong wind gusts can also damage buildings, down trees and blow large vehicles off the road," EC says. "Remember, severe thunderstorms can produce tornadoes."
