---------------------------------------------------------------------
==discussion==
The remnants of hurricane Sandy will arrive late Monday as a large
and powerful post tropical fall storm over Southern Ontario.  It will
likely track from the Atlantic ocean across the mid Atlantic states
then take an unusual path towards the Lower Great Lakes.

If the storm curves towards the Eastern Seaboard, which a consensus
of numerous computer weather models continues to suggest, there is
little doubt the Northeastern United States will take the brunt of
the storm.  There is also the potential for significant impacts in
Southern and Eastern Ontario.  Significant rainfall appears likely
late Monday into Tuesday.  Strong and gusty winds will also accompany
this storm if it takes this path.  The storm will likely weaken later
Tuesday and on Halloween, but it will remain cool, damp and may still
be somewhat windy for the trick-or-treaters.

A narrow band of wet snow is possible over the Haliburton Highlands
and the higher ground southwest of Georgian Bay.  It may be the first
measurable snowfall of the season if temperatures flirt with the
freezing mark, but it does 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 interacting
with fronts can produce significant rainfall.  Persistent rain is
forecast near this front for today and Monday leading up to the
arrival of Sandy.  It may amount to 20 to 30 mm or more over this
period, especially across Niagara, southcentral Ontario and north to
Georgian Bay.  An additional 30 to 50 mm is expected with Sandy with
excessive amounts of 50 to 100 mm possible.  The forecast track would
also produce widespread 50 to 70 km/h strong winds across Southern
Ontario beginning later Monday.  Severe gusts to 100 km/h are also
likely, as well as storm force winds on the Great Lakes.
The combination of sodden ground, strong winds and some residual
leaves on trees will likely lead to areas with power outages due to
fallen limbs and some downed trees snapping wires.

It is important to put this storm in perspective.  The main reason it
continues to receive considerable press is the forecast intensity by
various weather models, as well as the heavily-populated Northeastern
United States that would feel its greatest impact.  Many weather
models continue to forecast the storm achieving an unprecedented low
central pressure as it comes ashore late Monday.  Generally speaking,
the lower the pressure: the more intense the winds and rain around
the storm.  Even if the computer models are overdoing the strength of
this storm, it may still be a memorable wind-blasted soaker of a fall
storm to reckon with.

Rainfall and wind warnings may be issued by Monday morning for parts
of Southern and Eastern Ontario as this event draws closer and its
exact path and intensity become less uncertain.

More information can be found in the tropical cyclone statement
issued by the Canadian Hurricane Centre of Environment Canada.

Special weather statement for:
      Greater Sudbury and vicinity
      Kirkland Lake - New Liskeard - Temagami
      Manitoulin - Blind River - Killarney
      North Bay - West Nipissing.

First significant snowfall of the season possible Monday.

---------------------------------------------------------------------
==discussion==
A large and powerful fall storm that is expected to affect Southern
Ontario is also threatening to spread snow into parts of Northeastern
Ontario for Monday.

Significant snowfall amounts of 5 to 15 cm are quite possible on
Monday. In addition strong northerly winds may also result in very
low visibility in blowing snow in areas where the temperature
Remains at or below freezing.

Snowfall amounts will depend on the exact track and intensity of the
storm itself as it moves closer to the regions on Monday. They will
also depend on the temperature, as areas where the temperature stays
just above freezing may receive some of the precipitation in the form
of rain or a rain-wet snow mix.

Special weather statement for:
      Western Quebec
      Eastern Quebec
      Central Quebec.

        Frankenstorm expected for Halloween.

---------------------------------------------------------------------
==discussion==
Category 1 hurricane Sandy is currently located off the coast of
Florida with winds of over 120 km/h. Sandy is expected to move
northward or northeastward while maintaining hurricane strength.
Sandy will gradually lose a few of its tropical characteristics in
the next few hours. On Monday, Sandy is expected to veer
northwestward toward the U.S. Eastern Seaboard. Current indications
suggest that Sandy will move inland around the New York area as a
very powerful storm.

The effects of the storm will be felt in Quebec by early next week.
As the storm approaches, strong winds and rain will affect Southern
and Central Quebec. There is still some degree of uncertainty as to
the storm's forecast track, so it is still too early to provide
details regarding precipitation amounts.

Meanwhile, the strong northeasterly winds that will develop ahead of
the system combined with high tides Monday night and especially
Tuesday night could produce higher than normal water levels in the St
Lawrence River, mainly in Quebec City region. This could result in
coastal flooding.

The public is advised to monitor future forecasts and warnings as
warnings may be required or extended.
