Snow Squall watchIssued at 4:04 p.m. EST Thursday 20 November 2014
Snow squalls are expected to develop. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate. Snow squalls are quite possible tonight as winds shift into the northwest and direct stronger snowsqualls into Simcoe County from Georgian Bay. Motorists should be prepared for hazardous winter driving conditions due to sudden nil visibility in bursts of heavy snow and blowing snow. Local snow amounts near 15 cm are expected in the strongest snow squalls.Details
Snow squalls cause weather conditions to vary considerably, changes from clear skies to heavy snow within just a few kilometres are common. Visibility may be significantly and suddenly reduced to near zero. Road closures are possible. Snow Squall Watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities. Environment Canada meteorologists will update alerts as required, so stay tuned to your local media or Weatheradio.
