     Experts say the storm will undergo bombogenesis, meaning that colder air is expected to mix with warmer sea air, leading to a swift drop in atmospheric pressure. The process leads to a so-called bomb cyclone.

     As the area where the two air masses meet, called the Arctic front, moves northward and eastward, conditions for bombogenesis should continue moving as well, Mr. Moore said.
