(David Donnelly/CBC)Parts of southern Manitoba are in for a big soaking on Monday.Environment Canada issued a special weather statement as a band of slow-moving rain stretches across the region from the Interlake to the U.S. border.The system is expected to shift east slightly through the day, then stall out and linger over the region until tapering off early Tuesday.Precipitation rates will vary, but bands of moderate to heavy rain are likely to develop, the weather statement says. That, combined with the slow movement of the system, will result in a lot of rainfall over much of southern Manitoba.Environment Canada said in an update shortly after 3 p.m. CT that between 10 and 20 millimetres of rain has fallen across the western Red River Valley so far on Monday. Another 10 to 20 millimetres is expected on Monday night before tapering off through Tuesday.The highest accumulations are expected over the western Red River Valley and southern Interlake, with 30-50 millimetres likely by Tuesday morning. Some areas, however, could see upwards of 60 mm.Winnipeg isn’t part of the special weather statement but is still going to get 15-25 mm of rain, Environment Canada forecasted.Amounts over the central Red River Valley are likely to be from 30-40 mm and then diminish toward the Ontario border, where 10-25 mm is expected.More news from CBC Manitoba:
