Bangor

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
2. 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.

Storm Prediction Center severe weather database, 1950 to 2025.

Every storm within 100 miles

1. 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.

National Hurricane Center HURDAT2, 1851 to 2025.

Smoke overhead

1. 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.

River crests

River gauges in Penobscot County, the county that contains Bangor.

River gauges

1. Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. 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.

The drought index is for Penobscot County, the county that contains Bangor.

1. The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

Every earthquake of magnitude 4 or more within 50 miles

1. 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 city centre.
2. 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).

Mapped landslides

Landslides mapped in Penobscot County.

Mapped by ME GS (9).

1. 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…

   National Weather Service narrative

   The combination of 3.00 to 4.00 inches of rain and the melting of a record snowpack led to flooding along the East Branch of the Penobscot River near Grindstone. The river crested around 2 feet above flood stage. The flooding affected mostly lowland wooded areas bordering the river along with portions of Route 11. The monetary value represents the total damages to public infrastructure across all of Penobscot county. The flooding continued into May.

   National Weather Service narrative

   A combination of 3.00 to 4.00 inches of rain which fell in late April along with the melting of a near record snowpack across northern portions of the county led to significant flooding across Penobscot county. The flooding initially began along smaller rivers and streams across northern portions of the county. These tributaries then flowed into the Penobscot River which flows south through the county. Flooding increased southward across the county as the flood crest moved south along the river.|Flooding was reported along the Penobscot River at Lincoln...Greenbush...Costigan...Milford...Old Town...West Enfield and Eddington.

8. Apr 19, 2008Flood$481,000
   National Weather Service narrative

   Melting snow contributed to rising levels on the Mattawamkeag River which eventually led to a prolonged interval of mostly lowland flooding along the river. This flooding affected mostly the Bancroft Road between the towns of Wytopitlock and Danforth and several camps along the river. However...3.00 to 4.00 inches of rain fell across the region toward the end of the month...along with continued snow melt...which enhanced the flooding. The late month flooding led to the evacuation of 15 homes in Mattawamkeag. The flooding continued into May. The monetary value represents the total damage to public infrastructure for all of Penobscot county. In this instance the damage occurred late…
