In its tropical cyclone report on the hurricane, the National Hurricane Center only referred to the system as "Unnamed Hurricane". The Natural Disaster Survey Report called the storm "The Halloween Nor'easter of 1991". The "perfect storm" moniker was coined by author and journalist Sebastian Junger after a conversation with NWS Boston Deputy Meteorologist Robert Case in which Case described the convergence of weather conditions as being "perfect" for the formation of such a storm. Other National Weather Service offices were tasked with issuing warnings for this storm in lieu of the typical NHC advisories. The OPC posted warnings on the unnamed hurricane in its "High Seas Forecasts". The National Weather Service State Forecast Office in Boston issued "Offshore Marine Forecasts" for the storm. Local NWS offices along the East coast covered the storm in their "Coastal Waters Forecasts".
