- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Hancock County: 0.
- Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

- Tropical storms and hurricanes (34 kt or more, still tropical) at closest approach. Post-tropical remnants with gale-force winds are listed but not counted. Direct: track within 50 miles; near: within 100 miles. Distance is measured to the county boundary for counties and to the city centre for cities, using positions interpolated hourly between HURDAT2 fixes.

- A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

These are the counts in NOAA's annual high tide flooding reports; they are not National Weather Service flood stages. Years with less than 80 percent of data are left out.

- Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
- Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

- Landslides mapped in the USGS compilation of landslide inventories across the United States (version 3.0, 2025), rated probable or better. The compilation joins inventories made by federal and state agencies for different purposes and areas, so the number mapped in a county reflects how closely it has been surveyed as much as how often its slopes fail. An area with few records may simply not have been mapped. Deaths are as recorded in the inventories; a slide listed in two inventories is counted once.

National Weather Service narrative
A severe ICE STORM hit sections of central and southern Maine from January 5 through January 9. One of the hardest hit areas stretched from Bridgton to Lewiston to Augusta to Waterville where ice accreted several inches thick on trees, power lines, and other exposed surfaces causing almost everyone in those areas to lose electrical service. Statewide, the storm knocked out power to about 365,000 customers, an estimated 840,000 people or about 70 percent of the state's population of 1.2 million people. About one third of those that lost power were without electricity for more than a week. For some, the electricity was off for up to 3 weeks. During this time, residents and those…

Rainfall totals generally ranged from 2.00 to 4.00 inches...with local totals in excess of 5.00 inches. The heavy rains produced flash flooding. Numerous roads were closed or damaged to varying extents due to washouts. Damage to bridges and culverts also occurred. Extensive road damage occurred in the vicinity of Winter Harbor and across the Schoodic Peninsula. Main Street in Winter Harbor was flooded with water up to the entrances of some businesses. Washouts and road closures were reported on Birch Harbor Road...Summer Harbor Road. Due to road damage...there was no access to portions of Acadia National Park on the Schoodic Peninsula. Near Prospect Harbor...both Route 186 and…

- Sep 30, 2015Flood$159,000
National Weather Service narrative
Rainfall totals of 3.00 to 6.00...locally up to around 8.00...inches occurred during the 30th. This led to extensive urban and small stream flooding. Numerous road closures occurred due to flooding...with 4 to 5 feet of water covering some roads. Extensive damage to bridges and culverts also occurred. Flooding and damage was particularly extensive in the areas around Ellsworth and Bucksport. Additional flooding and flood related damage was reported in the towns of Dedham...Surry...Sullivan...Penobscot and Trenton. A small mudslide occurred along Route 1A near the Ellsworth and Dedham town line. Gusty winds and saturated soil also combined to topple trees on to power lines and some…
- Aug 3, 2008Flash Flood$120,000
National Weather Service narrative
Thunderstorms producing rainfall rates of several inches per hour contributed to flash flooding around Blue Hill. Rainfall totals of up to 4.50 inches were reported at Blue Hill in a short time. The heavy rains occurred at the time of high tide. With streams already full due to the high tide...runoff from the heavy rains had nowhere to drain. Storm drains were quickly overwhelmed and streams quickly overflowed. Water depths of 3 to 4 feet were reported in some low lying areas of Blue Hill submerging vehicles and flooding some buildings. A stream near the Blue Hill Memorial Hospital overflowed and flooded the basement of the hospital with around a half foot of water. A local…

National Weather Service narrative
Low pressure moving northeastward from Georgia intensified off the coast of New England with storm force winds near the center and gale force winds extending to the Maine and New Hampshire coastlines. Astronomical high tides were occurring while the strong winds were hitting the coastline. At 11:26 EST, the Portland tide gauge read 12.6 feet, a foot above normal, and .6 feet above flood stage. Coastal flood damage due to the storm surge was light to moderate, but widespread, effecting the entire Maine and New Hampshire coastlines from the Merrimack River in Massachusetts to Eastport, Maine. Many piers in Maine were submerged. Route 1 at Lincolnville , Woolwich, Arrowsic, and…
