A flood outlook has been issued for the Mississippi River and Carp River watersheds as warmer temperatures and rainfall could trigger an early spring runoff.
The Mississippi Valley Conservation Authority released the watershed conditions statement Wednesday, warning that a significant warming trend is underway across the region.
Forecasters say daytime temperatures are expected to remain above zero through mid next week, with highs possibly climbing above 10C on March 10.
Rainfall totals between 20 and 30 millimetres are also possible.
Officials say the snowpack is currently about 150 per cent above normal.
Combined with warmer weather and rainfall, that could lead to rising water levels and faster flowing rivers and streams.
Unstable ice conditions may also develop, increasing the risk of ice jams in some areas.
Residents are urged to use caution near rivers and streams and keep children well away from waterways.
The conservation authority also recommends checking sump pumps, clearing downspouts and securing outdoor items that could be carried away by rising water.
The advisory remains in effect until March 13.
