Manitoba is warning that spring flood risk is increasing in parts of the province as warmer weather begins to accelerate snowmelt, with the Interlake and Parkland regions facing some of the greatest concern in the days ahead.
A provincial flood bulletin on Tuesday said flood potential is highest in the Fisher River and Icelandic River basins, while overland flooding is also possible in parts of southern and central Manitoba, particularly in low-lying areas where drainage remains frozen or blocked. Elsewhere in the province, flood risk is considered moderate to low.
The province said a stretch of warmer temperatures this week is expected to trigger snowmelt, although a return to below-freezing conditions later in the week should temporarily slow runoff. Temperatures are then expected to climb back to seasonal levels early next week, raising the possibility of a more rapid spring runoff period.
Runoff is expected to begin soon in the Fisher and Icelandic River basins, where flooding could become significant depending on how quickly melting occurs. Minor flooding is also possible along parts of the Red River valley and the Assiniboine River, including some low-lying areas, as spring runoff continues.
Officials said volunteers, local residents and several agencies are helping with flood preparations, including sandbagging efforts and the construction of protective clay dikes where needed.
The province urged Manitobans living near rivers, streams and other flood-prone areas to stay informed and be prepared, noting that spring conditions can change quickly if warm temperatures or rainfall arrive in a short period.
Forecasts will continue to be updated as runoff conditions evolve.
