Ranked by deaths, injuries, damage and size together.
- Flash Flooding and Debris Flow in Maine, December 18 to 22, 2023Low pressure began organizing in the Gulf of Mexico on the 16th, setting record low sea level pressures as it traversed the Southeast through the 17th.
- Flooding and Coastal Flood in Maine, April 16 to 25, 2007An area of low pressure over the southeastern United States on the morning of Sunday, April 15th, rapidly intensified as it slowly moved north to near New York City by the morning of Monday, April 16th.
- Flooding in Maine, April 15 to 18, 2014Mild temperatures and heavy rains contributed to rapid snow melt and ice movement during mid April. Rising river levels and ice jams led to flooding across portions of northern and eastern Maine.
- Flash Flooding and Flooding in Maine, May 1 to 6, 2023A broad area of low pressure across the Great Lakes region stalled out well to the west of the region early on Sunday, April 30th.
- Flash Flood and Flooding in Maine, December 23 to 24, 2022Beginning on December 22nd a powerful storm was developing over the Ohio River Valley. On December 23rd the center of the storm was deepening rapidly (974mb) as it lifted through the eastern Great Lakes.
- Flash Flooding and Flooding in Maine, March 30 to 31, 1998Rapidly melting snow caused by record-breaking warmth combined with rainfall to cause flooding on the Kennebec and Androscoggin Rivers and their tributaries. Many roads were closed due to the flooding.
- Flood in Maine, May 13 to 16, 2006Low pressure developed south of New England and remained nearly stationary from the 12th to the 15th resulting in over 12 inches of rain in some locations in a 72 hour period. Homes and businesses were damaged extensively. Many roads were washed out and impassable.
- Flooding in Maine, April 28 to 30, 2005A cold front moved through Maine on the afternoon of April 27th. Low pressure developed on the front along the coast of Maine late in the day and produced copious amounts of rainfall across the area into the morning of the 28th.
- Flooding and High Wind in Maine, December 13 to 19, 2010Low pressure tracking west of the region drew unseasonably warm moist air north across the region...with record warm temperatures in spots. The warm temperatures rapidly melted the 1 to 2 feet of snow on the ground across central and Downeast portions of the area.
- Flash Flood and Flooding in Maine, October 31, 2021A rapidly developing area of low pressure tracked across the Southern New England coast and directly over Western Maine on the evening of October 30th and into the early morning hours of October 31st.
- Flooding in Maine, March 17, 2007Low pressure formed along the southeast U.S. coast on the morning of March 16. Strong cold high pressure was anchored over southern Canada resulting in cold temperatures over the northeast. As low pressure moved north up the coast, precipitation began as snow over Maine.
- Flash Flooding and Flooding in Maine, September 7, 2008Moisture from the remnants of Tropical Storm Hanna brought very heavy rain and flash flooding to portions of Downeast Maine. The heaviest rains and most extensive flash flooding occurred across coastal portions of Hancock and Washington counties.
- Flash Flooding and Flood in Maine, June 26, 2023Slow moving showers and thunderstorms associated with a broad area of low pressure moved across western Maine through the night of June 25th and into the morning of June 26th.
- Flooding in Maine, April 16 to 18, 1996Low pressure moving through western New England caused flooding to parts of the state. Stream and rivers were already high from normal spring runoff and the ground was saturated. Copious heavy rains and mountain snowmelt sent streams and rivers over their banks.
- Flooding in Maine, April 3 to 4, 2005A low pressure system moving slowly northeast from through the Mid-Atlantic States spread rain into Maine during the afternoon of April 2. Heavy rain continued through the 3rd as the storm continued to move slowly northeast.
- Flood in Maine, April 28 to 30, 2018An above average seasonal snowpack and cold start to April which delayed snow melt contributed to an above average late April snowpack. Rainfall from the last week of April through the first week of May generally ranged from 2.00 to 3.00 inches.
- Flooding in Maine, January 19 to 22, 1996Heavy rains assosiated with strong south to southeast winds ahead of an intense low pressure center that moved northeast out of the Great Lakes combined with snowmelt caused by unseasonably warm air caused flooding along rivers and streams, washed out roads, and flooded some…
- Flash Flooding and Flooding in Maine, October 10 to 11, 1998A moist southeast flow from the Atlantic developed ahead of an intensifying low pressure center off the mid-Atlantic coast on Friday, October 9 and caused heavy rain to spread over southern Maine during the day.
- Flash Flooding and Flooding in Maine, April 22 to 26, 2000A weakening area of low pressure was located over the state of Michigan at 7 pm on the 21st as a secondary low developed over northern Virginia. Precipitation began falling in southwestern Maine during the late afternoon and evening of the 21st.
- Flooding in Maine, February 25 to 27, 2010Strong coastal low pressure produced 3 to 5 inches of rain resulting in county wide flooding of small rivers and streams across portions of southern Maine. Road washouts were numerous with moderate to major damage occurring to roadways. Homes and businesses were also flooded.
- Flash Flooding and Flooding in Maine, September 17 to 19, 1999A southeast flow of tropical moisture developed over Maine late Wednesday, September 15 as Hurricane Floyd moved slowly northeastward along the East Coast of the United States.

- Flooding in Maine, January 27 to 30, 1996Flooding was produced over sections of Maine when the last and most intense storm in a series of three low pressure centers moved northeastward from the Great Lakes. South to southeast winds brought warm temperatures and heavy rainfall to the area.
- Flooding in Maine, August 8, 2008An area of very slow moving showers produced 3 to 5 inches of rain in southwest Maine which caused small rivers and streams to flood. Many roads in numerous towns were washed out. Evacuations took place at a campground and trailer park in Lebanon.
