"Nor'easter" is a writer's term or another state's term that has taken root with weathermen the last couple decades. Having grown up on an island in Maine with generations going all the way back, the term was seen puzzlingly by old timers when in print it was claimed it was a traditional term. On the coast of Maine the wind direction is nōtheast, with a long O and hard th as in loathe the term nor'easter.
But that's just my take. It works for a quiz I guess.
