Keep your umbrella handy because we are in for a downpour in Huntsville. The rainfall warning continues for Parry Sound-Muskoka. Up to 35 millimetres total is expected today with risk of thunderstorms. Environment Canada says this amount of water can cause flash floods and water pools on roads. If you’re out driving, you might want to take it easy on the roads, especially if you see a massive puddle.
