An overland flood watch has been issued for certain areas in southwestern Manitoba due to heavy rainfall expected to persist through Saturday. The province’s hydrologic forecast center announced the watch, forecasting widespread rainfall of 20 to 40 millimeters for much of southwestern Manitoba, reaching north towards the Dauphin region. The most intense rainfall is anticipated to occur west of Brandon, encompassing Virden and Melita, where 50 to 80 millimeters of precipitation is projected. Some areas might experience up to 120 millimeters from severe thunderstorms, posing a risk of overland flooding.
The heavy rainfall may also extend to the west into the Saskatchewan region of the Souris River basin, as highlighted by provincial authorities. Environment and Climate Change Canada has issued special weather statements for various parts of western Manitoba, with ongoing alerts in effect for the Dauphin and Riding Mountain National Park areas. The weather forecast indicates continuous rain in southeastern Saskatchewan and parts of western Manitoba throughout the day, tapering off overnight.
In a previous development, a flood warning was issued for western Manitoba at the end of June. Many communities in the region, including Dauphin, Minitonas, and Swan River, faced significant impacts from heavy storms and flooding earlier this year. Numerous municipalities have declared local states of emergency due to the effects of flooding and severe weather events.
Looking ahead, Environment Canada’s forecast for Winnipeg on Friday afternoon predicts periods of rain starting around midnight on Saturday and lasting through the morning. The region remains vigilant as the potential for further heavy rainfall poses concerns of increased flooding risks.
