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.

Every large fire

1. Large fires mapped by the Monitoring Trends in Burn Severity program since 1984: 1,000 acres or more in the West, 500 or more in the East. Prescribed burns are excluded. Acres here are the part of each perimeter inside this place.

Monitoring Trends in Burn Severity (USGS and U.S. Forest Service), 1984 to 2026.

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 Worcester County, the county that contains Leominster.

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 Worcester County, the county that contains Leominster.

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.

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 Worcester County.

Mapped by NASA (2).

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.

1. Dec 11, 2008Ice Storm, Northern Worcester$20.0 million
   National Weather Service narrative

   Up to an inch of ice accumulated on exposed surfaces resulting in the downing of numerous trees, branches, power and phone poles, and wires across northern Worcester County. Many of these trees fell on cars and houses and blocked roads, resulting in the closure of some of the roads.

2. May 31, 1998Thunderstorm Wind$10.0 million
   National Weather Service narrative

   Severe thunderstorms moved through central and southern Worcester County and caused intense downbursts between about 10 PM and 1030 PM. Two primary macroburst paths were identified by a National Weather Service survey on June 1st. The more southern path produced locally severe damage in parts of Charlton and Oxford, where a wind gust to 60 mph was reported by a spotter. It may be possible to trace this path back to the Brookfield, Brimfield, and Wilbraham areas, where there also were reports of wind damage. A second macroburst path could be traced nearly west to east across central Worcester County, from North Brookfield through Spencer, Leicester, Worcester, Shrewsbury, and…

3. Aug 4, 2018Tornado$5.0 million
   National Weather Service narrative

   In just about one minute, an EF-1 tornado, with maximum winds estimated at 110 mph, wreaked havoc in the easternmost portion of Dudley, MA and in the downtown portion of Webster, MA. It touched down along Route 12 (Schofield Avenue) to the west of Laprise Court in Dudley and traveled northeastward onto Main Street in Webster, then lifted near the French River by Oxford Avenue. ||Many trees were snapped and debarked. In Webster, a gas station overhang was twisted. An old brick rooftop was damaged, with bricks having fallen onto Main Street. The rubber roof covering of another building was peeled completely off. Windows were blown out at a business on Main Street and the street was…

4. Mar 29, 2010Flood$4.0 million
   National Weather Service narrative

   Three to seven inches of rain fell across portions of Worcester County, resulting in the Blackstone River at Northbridge rising to minor flood. The Nashua River at Clinton also rose above flood stage. Several roads and basements flooded in Leominster, Fitchburg, Lancaster, Milford, Mendon, Blackstone, Northbridge, and Shrewsbury. Reduced speed limits were imposed on the rail line between Framingham and Worcester.||Clinton experienced substantial flooding two weeks prior to this event. The Nashua River at Clinton crested only four tenths of a foot lower than that event. However, because of the recent flooding, many preparations were made in advance of the rainfall. Roughly 10,000…

5. Dec 11, 2008Ice Storm, Southern Worcester$3.0 million
   National Weather Service narrative

   Up to six tenths of an inch of ice accumulated on exposed surfaces across southern Worcester County. Trees, large limbs, and wires down in Worcester, Auburn, Charlton, Grafton, Oxford, Worcester, and Shrewsbury. Several trees landed on houses and one landed on a boat.

6. Mar 14, 2010Flood$2.7 million
   National Weather Service narrative

   The Nashua River at Clinton rose to flood stage after three to six inches of rain fell across Worcester County. Two factories in Clinton were closed after ten feet of water flooded the basements. In addition, two to three hundred feet of railroad tracks were washed out. Several cars were submerged in flood waters throughout Clinton. Two sections of Clinton were flooded: the Main and Church Streets area, where Coachlace Pond overflowed a culvert and the Water Street section near the Nashua River. Many streets were closed and several businesses along Main Street were damaged by floodwaters. The U-Haul storage facility on High Street was flooded. Several apartments throughout town…

7. Dec 7, 1996Heavy Snow, Southern Worcester$1.4 million
   National Weather Service narrative

   A low pressure system centered over Georgia at 7 AM on December 7th moved rapidly northeast across North Carolina. The intensifying system then moved nearly parallel to the Mid-Atlantic coast with its center reaching Plymouth County in southeastern Massachusetts during the early morning hours of December 8th. Temperatures rose into the 50s along and east of the track of the low center...over Plymouth County and Cape Cod. Heavy precipitation occurred across all of Massachusetts with rain over coastal areas and the southeast part of the state and heavy snow in all of western and central Massachusetts and much of Middlesex and Essex counties in the northeastern part of the state. A…

10. Jan 7, 1996Heavy Snow, Southern Worcester$1.3 million
    National Weather Service narrative

    An intense East Coast low pressure system moved northeast from eastern Georgia passing along the coast of the Carolinas and then close to 40 degrees North and 70 degrees West. This storm was one of the most significant winter storms to hit southern New England in the past 20 years and was named "The Blizzard of '96" as it dumped record snowfalls from the mid-Atlantic states to southern New England. Technically, this storm only reached a true blizzard by National Weather Service criteria for a few hours in a small section of eastern Massachusetts around South Weymouth during the early morning hours on January 8th. Very heavy snowfall, which was measured in feet, was the main effect…
