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.

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.

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 Androscoggin County, the county that contains Lewiston.

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 Androscoggin County, the county that contains Lewiston.

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 Androscoggin County.

Mapped by ME GS (16).

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…

   Heavy rainfall measured between 4 to 5.5 inches fell across Androscoggin County. Small streams rapidly responded with flooding in several communities including Livermore, Turner, Auburn, Leeds, and Wales. The hardest hit area was Wales where numerous road closures including Route 132 which significantly disrupted travel in and out of the area. A washout on Turkey Lane in Livermore led to basement flooding of a nearby property.

This intense low in combination with high pressure over eastern Canada produced Overview: An area of low pressure intensified rapidly as it moved slowly from the southeastern United States on the morning of Sunday, April 15th to near New York City by the morning of Monday, April 16th. The intense low over New York City in combination with high pressure over eastern Canada produced a very intense pressure gradient across the area which caused strong east to northeast winds to…

   Thunderstorms with heavy rain resulted in flash flooding in the town of Minot.

5. Dec 21, 2013Ice Storm, Androscoggin$627,000
   National Weather Service narrative

   A major winter storm affected the State of Maine from December 21st, 2013, through January 6th,, 2014. A mixture of precipitation fell across the state from December 21st through the 23rd with snow across northern areas, a mixture of snow and sleet across north central areas, a mixture of sleet and freezing rain across south central areas, and a mixture of freezing rain and rain in southern areas. Due to the weight of the ice on tree branches and limbs from freezing rain, widespread power outages occurred in portions southern and central Maine. Because subfreezing temperatures followed the storm and persisted for about two weeks, the ice remained on the trees for a prolonged…

6. Apr 28, 2005Flood, Androscoggin$600,000
   National Weather Service narrative

   A 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. Rainfall amounts of over 4 inches were common in Waldo and Knox Counties. Cushing received 7.85 inches, West Rockport received 6.63 inches, Camden received 5.28 inches, and Sedgewick received 4.13 inches. This event and the rainfall event of the 24th and 25th caused many rivers and streams to rise over their banks flooding and washing out roads. Many roads were closed which caused a major disruption to travel.The Presumpscot River at Westbrook rose above…

7. Dec 19, 2023Flood$560,000
   National Weather Service narrative

   The Androscoggin River reached moderate flood stage on December 18th and remained in flood stage through the 20th. The flooding was the result of heavy rain and snowmelt, driven mostly by routed water from the western Maine Mountains where runoff was 8 to 10 inches between rainfall and snowmelt. Major flooding unfolded upstream in Rumford, with a dampening of the floodwave as it moved into Auburn. The flooding reached Center Street in Auburn, cutting off a main thruway. There were businesses impacted along North River Road near Center Street and along Riverside Drive. Flooding also occurred in Lewiston, where people were evacuated along Tall Pines Drive, Avon Street, Winter…

8. Dec 11, 2008Ice Storm, Androscoggin$557,000
   National Weather Service narrative

   A major winter storm brought a mixture of snow, sleet, and freezing rain to Maine from the morning of December 11th to the morning of December 12th. The greatest impact in the state was in coastal counties of the state where a significant ice storm occurred. Following the ice storm, recovery and restoration efforts were negatively impacted by additional winter weather events that passed through the state. ||The ice storm was caused by an area of low pressure that moved northeastward along a stalled frontal boundary off the East Coast. Near ground level, cold air from eastern Canada funneled southward into the region on northerly winds. Southerly winds at higher levels of the…

9. Apr 16, 1996Flood, Androscoggin$520,000
   National Weather Service narrative

   Low 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. Roads and embankments were severely damaged, basements were flooded, and two small dams failed.Storm damage to non-federal public property was estimated at $2.5 million from the storm, including river and coastal flooding damage and the landslump damage to public property. A Federal disaster was declared for the counties of Androscoggin, Cumberland, Knox, Oxford, and York.

    Moose Hill Pond overtopped and caused excessive flows on Redwater Brook. This resulted in flooding of the water treatment plant and significant damages.
