A dangerous winter storm about to affect Southern and Eastern Ontario.
Winter Storm Warning is now in effect for:
Simcoe, Delhi, Norfolk, Port Dover, Waterford, Townsend, Caledonia, Cayuga, Haldimand, Dunnville, and Niagara Region.
Over the Niagara and Simcoe-Dunnville areas snow at times heavy has settled in. It will continue into the overnight hours before tapering off Thursday morning. Total snowfall amounts are expected to be in the 15 to 20 cm range with local 25 possible. The falling snow combined with northeast winds gusting to 60 or 70 km/h will create considerable blowing snow with reduced visibilities frequently less than 500 metres.
Highest snow amounts over Ontario are expected over Dunnville,
Niagara, and from Kingston to Cornwall with 15 to 20 cm or more and
very poor visibilities in blowing snow. Hence winter storm warnings
are in effect for these areas.
Areas from Windsor to Simcoe and Hamilton, and from Cobourg to Smiths
Falls and Ottawa are expected to see 10 to 15 cm of snow with this
Further north, from Sarnia to Kitchener to Toronto to Bon Echo Park
to Renfrew, snowfall amounts will likely be in the 5 to 10 cm range.
The reason why more snow is not expected in this swath is the shorter
duration of snow on the outer fringe of the snow area.
Impacts will be significant for travellers. It is a widespread event
and many regions have not experienced a significant snow event for
some time. The falling snow combined with northeast winds to 50 or
60 km/h will create fairly widespread blowing snow and poor
visibilities. This will be especially true in the Niagara region
where snowfall amounts will likely be highest. Also, holiday rush
hour Thursday morning may be problematic since much of the snow will
have fallen tonight.
