The Lake Simcoe Region Conservation Authority advises that warmer weather accompanied by rainfall is expected to begin to move through the watershed on Sunday, February 18th.   This weather system is expected to bring temperatures well above seasonal values with daytime highs climbing towards +5 to +10C by Monday afternoon.   Rainfall amounts of 10-15 mm are predicted on Monday with an addition 10-15 mm of rainfall potential for both Tuesday and Wednesday. 

Currently, portions of the watershed have a considerable snow pack.   Due to the four day duration of the expected thaw, a significant reduction of this snow pack will occur.  The expected rainfall coupled with the amount of ice and snow in storm drainage systems will increase the potential for blockage and ice jams, especially in the vicinity of culverts and bridges.  This may result in localized flooding in some areas.

Also, warmer than normal temperatures will reduce or eliminate ice cover in our creeks and rivers, resulting in dangerous ice conditions.   Children and pets should be warned to stay away from all watercourses.

This Watershed Conditions Statement will be in effect through Friday, February 23rd, 2018.

Duty Officer
