With warmer weather very definitely on the way (and a sudden burst of cold precipitation soon to follow) the provincial government has put out their first flood bulletin of the season, with some regions clearly experiencing more risk than others.
As per the bulletin, the Interlake region including the Icelandic River and Fisher River basin is under an increased flood risk, while the Parkland region is listed as at an elevated risk of overland flooding.
The report, made by Manitoba Transportation and Infrastructure’s Hydrologic Forecast Centre, shows a moderate to low flood risk everywhere else in the province. Snow-water content in the Parkland area is considered to be above normal.
“With warmer temperatures expected in the coming two days, snowmelt may occur and create overland flooding in parts of southern and central Manitoba, including the Parkland region,” reads a release from the province. “Temperatures are forecasted to fall below-freezing levels from Thursday to Sunday, slowing the snowmelt rate. However, temperatures are forecasted to return to seasonal normals of above-zero degrees starting early next week (April 20) and increasing the potential for a rapid, concentrated spring runoff period once melting begins.”
Runoff is partially underway along the Assiniboine River but peak levels are not expected until April 25. By that time, levels could exceed bankfull capacities at some locations and create minor flooding of low-lying areas.
