Sandy will be an historic storm –
as of Sunday evening, this is a virtual guarantee as all forecast
models are in strong agreement, predicting the worst case scenario of a
landfall just south of New York City late Monday.
This storm deserves the hype, but it is very important to separate the US impacts from the Canadian impacts.
Southern
Ontario is going to take the hardest hit from Sandy. There will be wind
and rain in Quebec and the Maritimes, and even snow in Northeast
Ontario, but the worst conditions are likely in Southern Ontario.
However, this is unlikely to be an epic storm for us – rather, Sandy’s
impact will be on par with a strong fall storm, the type we see every
few years. Strong winds from Sandy will lead to some scattered power
outages. It will be very windy later Monday into Tuesday morning -
guaranteed - the only question is how strong the gusts will be.
Peak
gusts for most places should remain below 100 km/h – still strong
enough for some trees to come down and some power outages, but not heavy
damage.
The exception
to this will be along the southern shores of the Great Lakes. In fact,
Sarnia may end up seeing some of the strongest winds of anyone Monday
night – not what you’d think considering Lake Huron will be farther from
the centre of the storm than Lake Ontario.
This
storm will behave more like a large fall storm than a hurricane once it
has moved inland, and the northerly wind blowing down the length of
Lake Huron coupled with colder air on the backside of the storm means
that areas around Sarnia may see wind gusts in excess of 100 km/h.
This could be enough to cause significant shoreline erosion and potentially infrastructure damage.
Motorists
in Southern Ontario should keep in mind that a strong grip on the wheel
will be needed on the Burlington Skyway and Garden City Skyway,
especially Monday night.
Recent
rainfall has saturated the ground in Southern Ontario, and with heavier
rain developing later Monday as Sandy’s moisture moves in, some
flooding is possible. However, this is not expected to be a Hurricane
Hazel type historic rainfall.

It may be historic because he broke down the dam of false facts that had a plurality of Americans suspisious about climate change.
