    Midweek Storm Raises Flooding Concerns for Alberta

    A storm ejecting out of the Rockies will spread rain across the Canadian Prairies, raising the risk of flooding on Wednesday.

    Rain is expected to fall from Alberta to southern Manitoba with the heaviest rain focusing over central Alberta. This includes the cities of Edmonton and Red Deer.

    Rainfall totals are forecast to range between 1 and 2 inches (approximately 25-50 mm) in the heaviest rainfall, with low-lying and poor drainage areas being the most susceptible to flooding.

    In addition to the heavy rainfall, melting snow will also contribute to the flooding concerns.

    Temperatures across southern Alberts rose well above the freezing mark both Monday and Tuesday, causing snow in the lower elevations to melt and flow into nearby streams and rivers.

    With rivers already running above normal, Wednesday's rain will only add to the rising waters and accelerate the onset of the flooding.

    Rain will taper off to a few showers by Thursday, possibly ending as snowflakes as colder air returns to the Prairies.

    Water levels will still remain high in the wake of this storm as it takes several days for all of the water to flow downstream and river levels to return to normal.

    Fortunately, this event does not look as significant as June 2013 when major flooding forced evacuations of thousands of people in the Calgary area.
