    A RARE type of winter storm hit the US South-east on Wednesday, dumping snow on Florida's capital for the first time in three decades and snarling travel, while New England braced for a "bombogenesis" blizzard forecast to bring heavy accumulations on Thursday.

    Bombogenesis, also known as a bomb cyclone, occurs when a storm's barometric pressure drops by 24 millibars in 24 hours, greatly strengthening the storm.
