John McIntyre rules against "Frankenstorm":
Yesterday, I sent this message to the newsroom staff: We will not be using the word “Frankenstorm” in coverage of Hurricane Sandy, because the term trivializes a serious and potentially deadly event. It’s acceptable in direct quotes, but even there we shouldn’t overdo it.
Christopher C. Burt, "Late Season Tropical Storms that have affected the U.S. north of Hatteras", 10/26/2012, surveys a dozen examples from history, including one of special interest to fans of Benjamin Franklin:
David M. Ludlum in his classic book ‘Early American Hurricanes: 1492-1870’ (American Meteorological Society, 1963) said this about the storm:
The storm that raced northward along the Atlantic Coast on November 2, 1743 deserves a unique place in the annals of American meteorology. Not only was this the first tropical storm in America to be measured accurately by scientific instruments, but it also provided Benjamin Franklin with a key to unlock for the first time the secret of a storm’s forward movement.
Franklin noted that in Philadelphia the barometer fell to 29.35” (994 mb) and the damage done both on land and at sea was “the worst in  years”. The same was said in Boston where a storm surge overwhelmed the city wharves and flooded the streets of the city. Storm surge flooding was also reported at Piscataqua and damage was reported inland at Newbury, New Hampshire. It has been called the ‘Eclipse Hurricane’ because it occurred during the night of a total lunar eclipse (which Franklin was disappointed to miss because of the storm’s cloud cover). However, Franklin noted the times that the storm struck at various locations between Philadelphia and Boston and the change in prevailing wind directions and thus was able to discern how the path of a storm and its wind circulations were related.
The Great New England Hurricane of 1938 was not "late season" enough to make his list — it make landfall on Sept. 21, and Burt surveys storms that arrived from the last week of October onwards — but it exemplifies an earlier fashion in storm naming, being variously known as "the Yankee Clipper" and "the Long Island Express", due to its extremely rapid forward speed (up to 70 mph). In those days, though, all the naming came in discussions after the fact, since predictions were not very good; so concerns about sensationalizing and/or trivializing major weather events didn't apply in the same way.
When I was growing up in rural eastern Connecticut, people still talked about the 1938 hurricane, because it had re-made the local landscape to a significant extent. We used to pick wild blueberries in the bed of a former lake whose dam had been smashed in 1938 and never replaced — the wreckage of the dam, down a dirt road in the middle of the woods, was the object of some childhood curiosity.
