Through Tide, Atmospheric pressure and High-pressure area

The nor'easter increased tides across the northeastern United States for several days due to its slow movement. In New York City, tides reached 8.04 ft (2.45 m) at Battery Park, which flooded Franklin D. Roosevelt East River Drive. Along Long Island, the nor'easter destroyed over 130 homes and left 454,000 people without power. In New England, 230,684 people lost power during the storm. Five houses were destroyed in Massachusetts, and flooding reached 5 ft (1.5 m) deep in Boston. Further inland, the storm produced significant snowfall, estimated at around 4 ft (1.2 m) in The Berkshires. The high snow totals closed schools for a week in western Massachusetts. Overall, the storm caused between $1–2 billion in damage (1992 USD) and 19 deaths, of which four were directly related to the storm. In March of the following year, the Storm of the Century caused worse damage across a larger region of the eastern United States.

Meteorological history

A storm complex moved eastward from the Texas coast into Georgia on December 9. On December 9, the National Weather Service (NWS) issued a coastal flood watch in anticipation of the developing storm. On December 10, an upper-level trough was located along the East Coast of the United States. At around 1200 UTC that day, cyclogenesis – the development of a low pressure area – occurred over southeastern Virginia. The cyclone moved quickly northward through the Chesapeake Bay until reaching a position just west of Chestertown, Maryland on December 11. By that time, the system had intensified to a pressure of 985 mbar (29.1 inHg), while the parent trough extended from Maryland through the New York metropolitan area to around Cape Cod. On December 11, the NWS issued gale warnings and advised for boats to avoid the ocean. The storm turned to the southeast and briefly stalled near Georgetown, Delaware. This was due to a high pressure area north of Maine halting its motion. The interaction between the two systems produced strong easterly winds from Virginia to New England. The nor'easter finally moved offshore on December 12, and later that day passed to the southeast of Long Island.
