The Christmas 1994 nor'easter was an intense cyclone along the East Coast of the United States and Atlantic Canada. It developed from an area of low pressure in the southeast Gulf of Mexico near the Florida Keys, and moved across the state of Florida. As it entered the warm waters of the Gulf Stream in the Atlantic Ocean, it began to rapidly intensify, exhibiting traits of a tropical system, including the formation of an eye. It attained a pressure of 970 millibars on December 23 and 24, and after moving northward, it came ashore near New York City on Christmas Eve. Because of the uncertain nature of the storm, the National Hurricane Center (NHC) did not classify it as a tropical cyclone.
Heavy rain from the developing storm contributed to significant flooding in South Carolina. Much of the rest of the East Coast was affected by high winds, coastal flooding, and beach erosion. New York State and New England bore the brunt of the storm; damage was extensive on Long Island, and in Connecticut, 130,000 households lost electric power during the storm. Widespread damage and power outages also occurred throughout Rhode Island and Massachusetts, where the storm generated  waves along the coast. Because of the warm weather pattern that contributed to the storm's development, precipitation was limited to rain. Two people were killed, and damage amounted to at least $21 million.

The storm originated in an upper-level low pressure system that moved southeastward from the central Great Plains into the Deep South of the United States. After reaching the southeast Gulf of Mexico, the disturbance underwent cyclogenesis, and the resultant system moved through Florida on December 22 in response to an approaching trough. National Hurricane Center forecaster Jack Beven noted that "as it moved out into the Bahamas, it appeared to take on the characteristics of a tropical storm." The uncertain nature of the storm prevented the NHC from issuing advisories on it, and forecasters lacked sufficient data to fully assess the cyclone for potential tropical characteristics. The same trough that pushed the storm across Florida had moved to the north, allowing for high pressure to develop in the upper levels of the atmosphere.
Deemed a "hybrid storm", the cyclone rapidly intensified in warm waters of up to  from the Gulf Stream combined with a cold air mass over the United States. The system continued to rapidly intensify while moving within the Gulf Stream; it developed central convection, an unusual trait for an extratropical cyclone, and at one point exhibited an eye. Despite these indications of tropical characteristics, "There was no front associated with it and it had a warm core, but the radius of maximum winds was more than , so under the standard NHC criteria it didn't qualify as a tropical storm." On December 23 and 24, the nor'easter intensified to attain a barometric pressure of . An upper-level low pressure system that developed behind the storm began to intensify and grew to be larger in size than the original disturbance. In an interaction known as the Fujiwhara effect, the broad circulation of the secondary low swung the primary nor'easter northwestward towards southern New York and New England. The original low passed along the south shore of Long Island, and made landfall near New York City on December 24. Subsequently, it moved over southeastern New York State. On December 25, the system began to rapidly weaken as it moved towards Nova Scotia, before the pair of low pressure systems moved out to sea in tandem in the early hours of December 26.

In South Carolina, flooding associated with the cyclone was considered to be the worst since 1943. Over  of rainfall was reported, while winds brought down trees and ripped awnings. In addition, beach erosion occurred along the coast. As a result of the heavy rainfall, several dams breached. Extensive flooding of roads and highways was reported, many of which were closed as a result. Up to  of water flooded some homes in the region. Approximately 300 people in Florence County were forced to evacuate because of the flooding, and at least 200 homes were damaged. Two deaths were reported in the state. One woman was killed when her vehicle hydroplaned and struck a tree, and another person drowned after her car was struck by another vehicle. Total damage in South Carolina amounted to at least $4 million dollars.
Strong winds occurred along the North Carolina coast. Diamond Shoals reported sustained winds of , and offshore, winds gusted to . On Wsville Beach, rough surf eroded an  ledge into the beach. On Carolina Beach, dunes were breached and some roads, including portions of North Carolina Highway 12, were closed.

As the primary storm entered New England, the secondary low produced minor coastal flooding in the Tidewater region of Virginia on December 23. Winds of  and tides to  above normal were reported. In Sandbridge, Virginia Beach, Virginia, a beachfront home collapsed into the sea. Several roads throughout the region suffered minor flooding. Strong winds resulting from the tight pressure gradient between the nor'easter and an area of high pressure located over the United States brought down a few utility poles, which sparked a brush fire on December 24. The fire, quickly spread by the wind, burned a field. The winds brought down several trees.
Damage was light in Maryland. Some sand dunes and wooden structures were damaged, and above-normal tides occurred. In New Jersey, high winds caused power outages and knocked down trees and power lines. Minor coastal flooding of streets and houses was reported. Otherwise, damage in the state was minor.
The storm brought heavy rainfall and high winds to New York State and New York City on December 23 and 24. Gusts of  downed hundreds of trees and many power lines on Long Island. Several homes, in addition to many cars, sustained damage. Roughly 112,000 Long Island Lighting Company customers experienced power outages at some point during the storm. As the cyclone progressed northward into New York State, high winds occurred in the Hudson Valley region. Throughout Columbia, Ulster and Rensselaer Counties, trees, tree limbs, and power lines were downed by the winds. At Stephentown, a gust of  was reported. Ulster County suffered substantial impacts, with large trees being uprooted and striking homes. Across eastern New York State, 25,000 households lost power as a result of the nor'easter. On the North Fork of Long Island, in Southold, a seaside home partially collapsed into the water.

In Connecticut, the storm was described as being more significant than anticipated. Gale-force wind gusts, reaching , blew across the state from the northeast and later from the east. Trees, tree limbs, and power lines were downed, causing damage to property and vehicles. The high winds caused widespread power outages, affecting up to 130,000 electric customers. As a result, electric companies sought help from as far as Pennsylvania and Maine to restore electricity. Bruno Ranniello, a spokesman for Northeast Utilities, reported that "We've had outages in virtually every community." In New Haven, the nor'easter ripped three barges from their moorings. One of the barges traveled across the Long Island Sound and ran aground near Port Jefferson, New York. A man in Milford was killed indirectly when a tree that was partially downed by the storm fell on him during an attempt to remove it from a relative's yard. Northeast Utilities, which reported the majority of the power outages, estimated storm damage in the state to be about $6–$8 million (1994 USD; $8.8–$11.8 million 2008 USD).
Effects were less severe in New Hampshire and Vermont. In southern New Hampshire, a line of thunderstorms produced torrential rainfall, causing flooding on parts of New Hampshire Route 13. Flash flooding of several tributaries feeding into the Piscataquog River was reported. In Maine, the storm brought high winds and heavy rain. Along the coast of southern Maine and New Hampshire, beach erosion was reported. Additionally, minor flooding was reported across the region, as a result of heavy surface runoff and small ice jams. In Rhode Island, the power outages were the worst since Hurricane Bob of the 1991 Atlantic hurricane season. Throughout the state, approximately 40,000 customers were without electric power. As with Massachusetts, downed trees and property damage were widespread. There were many reports of roof shingles being blown off roofs and of damage to gutters. In Warwick, several small boats were damaged after being knocked into other boats. The highest reported wind gust in the state was  at Ashaway, Rhode Island. Statewide damage totaled about $5 million.
Massachusetts, particularly Cape Cod and Nantucket, bore the brunt of the nor'easter. Reportedly, wind gusts approached  on Cape Cod and, offshore, waves reached . At Walpole, wind gusts peaked at , while on Nantucket gusts of  were reported. The winds  30,000 electric customers without power during the storm, primarily in the eastern part of the state. Power was out for some as long as 48 hours. Property damage was widespread and many trees, signs, and billboards were blown down. A large tent used by the New England Patriots was ripped and blown off its foundation. The winds also spread a deadly house fire in North Attleboro. Although not directly related to the storm, it caused seven fatalities. Because tides were low, little coastal flooding occurred. Outside the Prudential Tower Center in Boston, the storm toppled a  Christmas tree. Rainfall of  was recorded throughout the eastern part of the state, contributing to heavy runoff that washed away a  section of a highway. Total damage in Massachusetts is estimated at about $5 million.
