Sandy has been downgraded this morning from a minimum-strength hurricane to a tropical storm.

After battering the Bahamas, Sandy is headed north with winds of 110-kilometres an hour.

But forecasters expect it to merge with two other weather systems to become a monster storm that could be a major threat to New Jersey and other mid-Atlantic states early next week.

And, they say that storm will likely be felt by Canadians from southern Ontario to the Maritimes including us.

Bayshore Broadcasting Weather Specialist John Wilson says we'll feel the effects of this monster storm Tuesday and Wednesday.

Wilson says the storm is affectionately known as Frankenstorm - being a hybrid of a monster storm - just as Frankenstein was a hybrid monster.

Wilson says expect winds up to 80 km an hour with heavy rain both days - and that could affect plans for trick or treating Wednesday night.

Sandy is blamed for at least 43 deaths in the Caribbean.
