Parts of Simcoe County and cottage country could be in for a wet couple of days.

Environment Canada has issued a special weather statement warning of the possibility of 25 to 50 millimetres of rainfall by Thursday night.

The rain will come courtesy of a low pressure system moving east from Minnesota. The weather office expects thunderstorms to start late Wednesday night over Georgian Bay.

The statement has been issued for:

  • Barrie - Collingwood - Hillsdale

Environment Canada says there is still some uncertainty when it comes to where the storm is tracking.
