Weather experts expect heavy rain in Quebec today, Sunday, with widespread warnings of rainfall and special weather statements in the area. Some regions may see more than 100 mm by tomorrow, Monday, increasing the risk of flooding.

In addition to rainfall, conditions will be favorable for the development of severe storms with the risk of rotating storms in parts of the province. Flash flooding and tornadoes cannot be ruled out in parts of Quebec.

With the risk of severe storms and flooding increasing today, Sunday, the greatest risk for extreme weather will grow today as the center of the low-pressure system moves south into Quebec.

High instability, tropical humidity, and abundant wind shear flowing over the Montreal metro area and the eastern towns will allow thunderstorms to develop before the system arrives during the mid to late afternoon hours.
