Monroe County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Monroe County: 0.
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

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.

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.

NOAA NCEI nClimDiv county Palmer Drought Severity Index, 1895 to September 2026, issued October 6, 2026.

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 county boundary (or inside the county).
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

Mapped by NASA (1).

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.

   For the second time within seven months a greater than 50-year storm affected the Delaware River Basin and its tributaries. In all, about 5,715 homes were evacuated along the Delaware and Susquehanna Rivers in Pennsylvania. Pennsylvania Ed Rendell quickly declared a state of emergency and made money available to the Pennsylvania Emergency Management for flood related needs. Many homes and businesses that were flooded because of the remnants of Hurricane Ivan, were flooded again. The crests along the Delaware River were even higher than in September 2004 and were the highest crests since 1955. In many places, it was the second or third highest crest on record for the Delaware…

2. Jan 19, 1996Flood, Monroe$25.0 million
   National Weather Service narrative

   The combination of snowmelt from the previous week's two storms, unseasonably warm temperatures and an additional one to two inches of rain caused the flash flooding of almost every small stream and significant roadway flooding the afternoon and early evening hours on the 19th. Major flooding of the larger streams and rivers in Pennsylvania continued through the 21st. The flooding caused three deaths, all in Montgomery County, three injuries and about $50 million dollars in property damage. All of Pennsylvania was declared a disaster area and extra public assistance was given to Northampton, Bucks and Monroe Counties, the hardest hit counties in the Southern Poconos and Southeast…

   Several days of heavy rain throughout the Delaware and Lehigh River Basins culminated with major flooding along the Delaware River from the 28th through the 30th. It was the second highest crest on record for the Delaware River along Monroe County only surpassed by the flooding in August of 1955. The worst reported damage was along the Brodhead Creek and along the Delaware River. The crest along the Delaware River was slightly lower than the April 2005 flood. President George W. Bush declared Monroe County a disaster area. Two men drowned. Sporadic periods of heavy rain started on the 23rd, but the most widespread and heaviest rain fell from the night of the 27th into the morning…

   One of the worst ice storms in history to affect the Poconos occurred on January 5th and 6th. As nasty as that storm was, it was exacerbated by another ice storm on January 8th. At one point, nearly three-quarters of Carbon County was without power and nearly 46,000 homes and businesses in Monroe County lost power. Systemwide 238,000 Pennsylvania Power and Light customers lost power and the total repair cost was estimated at $25,000,000. Metropolitan Edison reported about 40,000 of its customers lost power. Thousands upon thousands of trees were knocked down or damaged. The number of outages cascaded. There were only 1,000 the morning of the 6th, but that increased to 27,000 the…

   The remnants of Hurricane Ivan interacting with a slowly moving cold front caused widespread very heavy rain to fall from the late evening of the 17th through the first half of the day on the 18th in Monroe County. Doppler Radar storm total estimates averaged between 3 and 6 inches throughout the county. The torrential rain caused widespread poor drainage, creek and river flooding. It was the worst flooding along the Delaware River since 1955. Every stream in the county flooded. About 160 homes and businesses were damaged. Extensive damage also occurred in the Delaware Water Gap National Recreational Area. President George W. Bush declared the county a disaster area. Damage was…

   Tropical Storm Isabel produced strong power outage producing winds, moderate tidal flooding along the Delaware River and stream flooding in Chester County. Isabel made landfall as a hurricane near Drum Inlet, North Carolina around 100 p.m. EDT on the 18th and weakened as it tracked farther inland. At one time in its life cycle, it was a powerful Category 5 hurricane when it was north of the Leewood Islands. Winds gusted up to 60 mph in Eastern Pennsylvania and downed countless numbers of trees, tree limbs and power lines. It was the worst outage on record for PECO Energy in southeastern Pennsylvania. About 572,425 of its customers lost power. This exceeded the outages that…

   National Weather Service narrative

   The Blizzard of '96, the second coined "STORM OF THE CENTURY" of this decade brought record breaking snow to most of Southeast Pennsylvania and paralyzed the region for several days, caused most municipalities to exceed their annual snow budgets during this one storm, caused several building collapses and caused directly or directly 42 deaths and countless injuries. Six persons died of hypothermia, 4 in Philadelphia, 1 in Delaware County and 1 in Lehigh County. Some were homeless persons, but one woman in Allentown accidentally locked herself out of her home. Twenty-nine persons suffered heart attacks and died while shoveling snow, using snowblowers or trying to walk in the deep…
