Environment Canada has issued a special weather statement for the GTA and other parts of southern Ontario.

The agency says that the remnants of Sandy, which has been downgraded to a tropical storm, will probably arrive late Monday as a
large and powerful post tropical fall storm over Southern Ontario. It  will likely track from the mid Atlantic states and take an unusual  path towards the Lower Great Lakes.

If the storm curves towards the Eastern Seaboard, which a consensus of numerous weather models suggests, there is little doubt the  Northeastern United States will take the brunt of the storm.

But  there is the potential for significant impacts in Southern and Eastern Ontario too. 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 windy.
