Eastern Ontario, including Renfrew County, is in store for heavy rain and thunderstorms following a special weather statement issued for the region.

Environment Canada says 15 to 25 milimetres of rain is on the way.

At this time of year the ground may not be able to absorb as much water and Environment Canada is advising you to stay away from any rivers or creeks.

The rain is expected to begin tonight and carry over into tomorrow morning.
