Hurricane Sandy is expected to morph with a cold front triggering a superstorm. The storm is heading for the U.S. East Coast, and remnants of may be felt in Ottawa as well.

The hurricane has killed more than 20 people in the Caribbean already. It’s still hitting the Bahamas, and residents of Florida are also feeling the effects.

Those who live in the U.S. East Coast — from New England to Virginia — are being told to brace for the storm because when it hits early next week, it could arrive as a devastating superstorm.

Some forecasters are referring it to as “Frankenstorm” because it will be a blend of two aggressive weather systems.

CNN meteorologist Rob Marciano said he’s never seen anything like this in his lifetime.

“You take a large hurricane like this, and then you combine it with this extraordinarily strong cold front and deep trough that’s going to be coming across the U.S. — almost winter-like air,” Marciano said.

“When this storm is going to start to weaken as it goes north as they typically do, the jet stream is going to give it some energy, and just blow this thing up,” he added.

Widespread power outages are expected with winds of more than 110 kilometres an hour.

The GTA could feel the storm’s impact on Tuesday and into Halloween on Wednesday, as it’s expected to bring with it heavy rain and wind.
