To the editor:

Sunday's intense storm was another of what we call "bomb cyclones." The pressure dropped 28 millibars in 24 hours, resulting in very strong winds with peak gusts 40 to 45 mph in some locales and accompanied by torrential, tropical-like rain.

Nearly 2 inches measured here at Salem (1.95 inches). Several times the rain was falling at the rate of an inch per hour!

Mike Matvichuk, a forecaster from Danvers, reported a thunderstorm during the heavy period of rain.

It is interesting to note the the term "bomb cyclones" was introduced by the former MIT meteorologist Fred Saunders, now deceased, of Marblehead. Fred and I often had discussions of weather events in the past.
