Lake effect snow will continue into the weekend as two more quick moving systems will bring widespread snow to the Upper Great Lakes. High winds are expected across portions of Montana through the weekend. Below normal temperatures will remain in place across much of the southern and eastern U.S., while the western U.S. will experience above normal temperatures. Read More >
This page provides a broad overview of most of the record breaking flooding that has occurred in the Northeastern United States. It does not attempt to document every flood that has occurred in the region.
Upon reviewing these cases, it can be seen that flooding can occur at any time of year, and can result from many different types of meteorological events. In general, a single large rainfall event may be sufficient to cause minor to moderate flooding. However, the largest floods in the northeast have generally been caused by two large storms falling in a 7 day period. It should also be remebered that all 6 inch rainstorms are not equal. A six inch rain in April, accompanied by snowmelt and wet soil conditions will have a much larger impact on the rivers than a 6 inch rain in August when soil conditions are normally much dryer and the vegetative cover consumes a large portion of the precipitation.
Following the disastrous floods in the early part of the 20th century, a large number of flood control projects were developed by the US Army Corps of Engineers. These have successfully reduced many flood peaks. However, the entire area obviously cannot be controlled and more floods are sure to come.
Date | Event Description |
November 1996 | Record flooding occurred just west of Lake Champlain following a 5-8 inch rainfall |
March/April 1987 | Heavy rains combined with snowmelt resulted in major flooding throughout New England. |

March 1968 | Heavy rain combined with snowmelt caused small river flooding in southeast New England |
August 1955 | Hurricanes Connie and Diane came a week apart to batter most of New England with the most significant flooding recorded at many locations. |

September 1938 | Widespread 10 inch rainfall caused by a hurricane resulted in major flooding throughout the Connecticut River valley |
March 1936 | Heavy Rain and melting snow caused major flooding throughout the Northeast and Middle Atlantic states |
