Powerful Nor'easter causes flooding and leaves hundreds of thousands without power

A powerful storm that slammed the Northeast Tuesday is expected to remain in the area as it slowly makes its way to sea.  

Flooding and other damage have been reported from New Jersey to Cape Cod. Waves pounded the Massachusetts shore overnight. The Nor'easter's brought nearly 90 mph winds, whipping water over entire houses. 

Crews cleared the roads of fallen trees south of Boston but not before some trees knocked down power lines, putting tens of thousands of residents in the dark.
