Winter Storm Warning – Simcoe, Delhi, Norfolk

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
event.

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.

Snowstorm coming Boxing Day?

A low pressure system is expected to develop over Texas on Christmas
day and then move northeastward to pass south of the Great Lakes
region late in the day boxing day into Thursday. Such a storm track
would place Southern Ontario on the cold side of the storm, with the
potential for significant snowfall accumulations.

Present indications suggest that the snow would start in the
southwest during the day on boxing day, and then spread eastward to
reach Eastern Ontario later in the evening. In addition, gusty
northeast winds would result in local blowing snow reducing
visibilities. Conditions should improve from west to east on
Thursday.

Current indications suggest that in areas from Lake Erie across
Niagara as well as the St Lawrence Valley area the potential exists
for snowfall amounts near the warning criteria of 15 cm in 12 hours.

Freezing Rain Warning Issued

Be careful travelling this afternoon, especially if you are heading north or west of the city of Brantford. A freezing rain warning has been issued for Tillsonburg, Oxford, Woodstock, London, Middlesex, Kitchener, Cambridge, Waterloo, Ancaster and Hamilton. Edit: Brantford, Delhi, Simcoe, Paris, Norfolk and Haldimand Counties added to the warning effective 2:30 pm.

The first real taste of winter may cause roads to be icy and if it changes to snow after ice is on the roads, driving my be treacherous. Be prepared for a quick change in road conditions.

Wind Warning Issed for Southern Ontario

Frankenstorm and Hurricane Sandy are starting to make their mark in southern Ontario. A wind warning has been issed for Brantford, Brant, Norfolk, Simcoe, Delhi, Oxford, Woodstock, Norwich, Tillsonburg, Hamilton, Niagara, St. Catharines, Kitchener, Waterloo, Cambridge.

The remnants of hurricane Sandy will arrive later today as a large
and powerful post tropical fall storm over Southern Ontario. It is
forecast to track from the Atlantic ocean northwest across the mid
Atlantic states towards the Lower Great Lakes.

The Northeastern United States will take the brunt of the storm.
However, there is the potential for significant impacts in Southern
and Eastern Ontario. Significant rainfall with strong and gusty
Winds appear likely late Monday into Tuesday. The storm is expected
to weaken later Tuesday and on Halloween, but it will remain cool,
damp and breezy for the trick-or-treaters.

Areas of wet snow are possible over the Haliburton and Dundalk
Highlands overnight tonight as well as Monday night where
temperatures may flirt with the freezing mark. However, accumulations
do not appear to be significant at this time.

A complicating factor is the presence of a stalled front now over
Southern Ontario. Moisture-laden post-tropical storms with rain bands
interacting with fronts can produce significant rainfall. Persistent
rain is forecast near this front for the remainder of today leading
up to the arrival of Sandy this evening. A total of 20 to 40 mm is
likely today through tonight due to Sandy’s effects, especially
across Niagara extending west towards the St Thomas area. Lesser
amounts are likely elsewhere. Rainfall warnings appear unlikely at
this time but cannot be ruled out completely.

Wind is more of a concern. The forecast track will likely produce
widespread 50 to 70 km/h winds across Southern Ontario beginning
later today with severe gusts to 100 km/h likely. Gale to storm
Force winds are expected on the Great Lakes and St. Lawrence River.
The combination of sodden ground, strong winds and some residual
leaves on trees will likely lead to some areas with power outages
Due to fallen limbs or downed trees snapping power lines.

Total rainfall amounts and strength of the winds will ultimately
depend on the exact track of this large fall storm. Wind warnings
will likely be issued by 5 AM for a wide swath of Southern and
Eastern Ontario. Rainfall warnings may be issued depending on Sandy’s
path as the event draws closer.
