Upwards of 100 millimetres of rain is expected by Friday.
A deepening low pressure centre currently over Northeastern Montana has generated an area of rain across Southern Alberta. As the system will be slow to move through Southern Saskatchewan today and into Manitoba on Friday rain will continue into Friday before becoming intermittent Friday afternoon. Rainfall amounts of 50 to 70 millimetres have already been reported in a few locations of the Crowsnest and Lethbridge regions. Total amounts of near 100 millimetres are expected to be widespread across the warning regions.
If this continues I'm going to need one of these!......
