I believe that this may have been one of the only tornadoes known to impact Islip while moving NNE
and forming south of Long island. It seems like most Western to Central Suffolk tornadoes have
more of an easterly heading and track along warm fronts or sea breeze boundaries. There was
also another Tornado to impact Breezy point early in September that formed south of Long island
with the very warm SST's.
The magnitude of the snowfall at Islip may have been considered a 100 year event, and it would
be interesting to see the specific numbers on that.
The sharp turn to the left of Hurricane Sandy into the New Jersey may have been considered a
a 714 year event. This recent study just completed is a very interesting read:
