  • Flood Outlook in effect until March 16

    Created: Wednesday, March 13, 2019

    The Lake Simcoe Region Conservation Authority advises that warmer weather accompanied by rainfall is expected to begin to move through the watershed on Wednesday, March 13th through Friday, March 15th.  This weather system is expected to bring temperatures well above seasonal values with daytime highs climbing above +10oC by Thursday afternoon.  Above zero temperatures are forecast for overnight Thursday and daytime highs climbing to +10oC on Friday.  In addition, rainfall amounts over 10mm are predicted on Thursday.


    Currently, portions of the watershed have a considerable snow pack.  Due to the 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 - Flood Outlook will be in effect through Saturday, March 16th, 2019
