A storm watch is underway.
Weather watchers on both sides of the border are tracking a system over the Northern Plains States that's expected to intensify into a major winter storm as it tracks across northwestern Ontario.
It's supposed to start as rain before changing over to snow this afternoon with strong winds.
We could see between 15 and 25 centimetres of snow is expected by the time the system moves out of the area tomorrow.
There's already a road closure to report.
OPP says Highway 622 between Atikokan and the Trans Canada Highway has been completely shut down due to icy conditions.
No word when it will be reopened.
