Heavy rain to drench southern Manitoba. Rain totals, here
A slow-moving system from the American Rockies will soak southern Manitoba to begin the week, with Winnipeg expected to receive up to 40 mm of rain.
A rainy start to the week is expected in southern Manitoba as a low-pressure system creeps in from the American Rockies and tracks across the Midwest.
The system is anticipated to drag a lot of rainfall northward, bringing widespread, drenching rain to most of the province by Monday morning.
Early projections indicate that rain will begin near the international border early Monday and reach Winnipeg by the end of the morning commute. By the afternoon, heavier rain bands will form west of Highway 75 and south of Dauphin.

A widespread soaking ahead
An upper-level low moving across the central Prairies will pick up the moisture and carry it into southern Manitoba through the Interlake Region. This combination suggests that rain will be consistent—and in some cases, intense.
A band of heavy rain of 30 to 50 mm is expected from southwestern Manitoba to the southern Interlakes, with Winnipeg receiving 20 to 40 mm. Some forecasts indicate that higher amounts may fall in the south, where the moisture feed is stronger.

When it all winds down
The system will remain until Monday night before gradually dissipating by Tuesday afternoon. Cooler air behind the system may bring a few lingering showers, but the majority of the precipitation will have passed by then.
Drivers should expect slick conditions, ponding on roadways and slower commutes Monday and Tuesday when the province's first major fall rainstorm hits.
