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 Cumberland County, the county that contains Portland.

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.

High tide flooding

Tide gauges in Cumberland County.

1. High tide flooding days are days on which a NOAA tide gauge recorded water at or above NOAA's minor flood threshold, set from the gauge's tide range, counted by meteorological year (May to April). 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.

NOAA CO-OPS high tide flooding counts, through April 2026, retrieved October 30, 2026.

The drought index is for Cumberland County, the county that contains Portland.

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).

Tsunamis

Tsunami records for Cumberland County.

1. Places where NOAA's Global Historical Tsunami Database records a tsunami's water arriving, with the greatest height it reached above sea level at the time. Only tsunamis NOAA rates probable or definite are counted. Heights from eyewitness accounts and tide gauges are mixed, and older events are less completely recorded.

Mapped landslides

Landslides mapped in Cumberland County.

Mapped by ME GS (178).

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 astronomical tide in Portland was 11.2 feet at 1205 pm. Flood stage is 12 feet (MLLW). The gale to storm force onshore winds produced a storm surge of 3.37 feet in Portland Harbor. The resulting storm tide topped out at 14.57 feet (MLLW) in the Forest City with the tide remaining above flood stage for two hours and 38 minutes, however, similar to the storm earlier in the week, localized flooding occurred throughout the day in low lying communities. The temporary new tide gauge at the Gulf of Maine Research Institute (GMRI) in Portland reached 14.6 feet (MLLW). ||The storm created significant damage to waterfront areas of Cumberland County due to both inundation flooding and…

4. Oct 21, 1996Flash Flood$15.0 million
   National Weather Service narrative

   A coastal storm which was fed tropical moisture by the circulation around Hurricane Lily produced between 4 and 19 inches of rain throughout the County during a 30-hour period. Many homes and businesses were flooded. Many roads and bridges were washed out. The city of Portland was without potable water for 24 hours as 4 major water mains were broken. One man drowned when the man and his wife attempted to drive across a flooded roadway that had been washed out. An area dam failed.

   National Weather Service narrative

   The morning of December 23rd had perfect alignment of a very high astronomical tide, peak storm surge of 2+ feet and large battering nearshore waves of 15 to 20 feet all coinciding at high tide. The astronomical tide in Portland was 11.3 feet MLLW at 10:16 am, already close to the established 12 foot MLLW minor flood level. The intense onshore winds produced a storm surge of 2.41 feet in Portland Harbor. The resulting storm tide topped out at 13.72 feet MLLW, it���s fourth highest water level in modern history for the Forest City (records 1912-present). The tide remained above flood stage for 195 minutes (945 am - 100 pm). A temporary new tide gauge installed by the Gulf of…

7. Apr 16, 2007Coastal Flood, Coastal Cumberland$7.0 million
   National Weather Service narrative

   High astronomical tides combined with strong northeast winds and large battering waves to produce severe coastal flooding across most of the Maine coast. It was the seventh highest tide ever recorded in Portland Harbor in modern day history (13.28 feet). The Fort Point tide gage reached 12.15 feet. Many roads were closed and residents evacuated. Damage to marinas, buoys, docks and coastal property was significant. Channel markers went adrift from their 20,000 pound blocks, causing navigation problems for mariners. The Portland Large Navigational buoy was heavily damaged while measuring 32 foot waves and was later found drifting near the Isles of Shoals. Water and waves were over…

8. Jan 24, 1998Ice Storm, Coastal Cumberland$3.0 million
   National Weather Service narrative

   Low pressure that developed off the southern New England Coast combined with an area of low pressure moving eastward from the Ohio River Valley to bring a mixture of precipitation to the state. Heavy snow was followed by sleet and freezing rain in most sections of the state, and rain in coastal and downeast sections. The freezing rain which began Friday night persisted in some areas into Saturday night. More than 75,000 customers (an estimated 170,000 people) lost electrical service during the storm as ice-laden trees and branches fell onto power lines, mostly in York and Cumberland Counties. Some of the power outages lasted several days. This storm came as power restoration…

9. Dec 11, 2008Ice Storm, Coastal Cumberland$2.9 million
   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…

    National Weather Service narrative

    A strong cold front moved through the region followed by a prolonged period of gusty northwest winds. The winds knocked over a battery charger at a bark mulch manufacturing operation in Windham, sparking a fire that caused an estimated $1.2 to $1.5 million in damages to a storage building and equipment. Winds gusted to 45 mph (measured) in Portland, and 44 mph (measured) in Lewiston.
