Boston bomb genesis: unprecedented storm effects

A “bomb cyclone” wreaking havoc in the Northeast on Thursday unleashed dangerous flooding in Boston and unprecedented high tides along the Massachusetts coast, trapping drivers in cars “floating” through ice-slushed streets covered in mini “icebergs.” 
High tide started to peak Thursday afternoon, with the height tying the one set during the blizzard of 1978, Boston25 reported. 
The National Weather Service compared the flooding to that set during that historic blizzard, and said Thursday’s storm brought in “some of the worst [to Boston] in recent history.”
