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

- 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.

- 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).
- 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).

- 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
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…
- Jan 19, 1996Flood, Carbon$3.0 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…
- Jun 27, 2006Flash Flood$2.1 million
National Weather Service narrative
Several days of heavy rain throughout the Lehigh River Basin culminated with flooding along the main stem of the Lehigh River. President George W. Bush declared Carbon County a disaster area. Sporadic periods of heavy rain started on the 23rd, but the most widespread and heaviest rain fell from the late afternoon of the 27th into the morning of the 28th. This caused flash flooding along smaller streams and exacerbated the ongoing flooding along the major rivers. Event totals in Carbon County averaged eight to twelve inches.Governor Ed Rendell declared a disaster emergency in the state on the 28th. In Eastern Pennsylvania approximately 5000 homes, apartments and businesses were…

National Weather Service narrative
The most powerful storm to affect Eastern Pennsylvania since the Blizzard of 1996 struck during the President's Day Weekend. Snow began falling around daybreak on Sunday the 16th in and around Philadelphia and then spread slowly north. It reached Reading around 9 a.m. EST, the Lehigh Valley during the early afternoon and the Poconos toward sunset. The heaviest snow fell in Philadelphia and its suburbs during the day into the early evening of the 16th. The snow mixed with sleet in Philadelphia and Delaware Counties from the evening of the 16th through the morning of the 17th. The heaviest snow in Berks County and the Lehigh Valley fell during the first half of the day on the 17th…
- Sep 18, 2003High Wind, Carbon$1.0 million
National Weather Service narrative
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…
- Jan 7, 1996Blizzard, Carbon$1.0 million
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…
- Aug 17, 2007Hail$750,000
National Weather Service narrative
Moth ball to tennis ball (2.5 inch diameter) hail fell across central and southeast Carbon County and caused considerable damage. In Nesquehoning, golf ball size hail covered the parking lot and damaged the vehicles of emergency responders at the 911 center. Hail as large as tennis balls fell in Franklin Township, as large as hen eggs around Palmerton, as large as quarters in Lehighton and as large as moth balls fell in Jim Thorpe. Hail also fell in Weatherly. Hail damage included broken home and vehicle windows, dented siding and broken skylights.

National Weather Service narrative
Hurricane Floyd battered Eastern Pennsylvania (especially Southeast sections around Philadelphia) on September 16th and brought with it torrential and in some places record breaking rains and damaging winds. The hurricane caused widespread flash flooding as storm totals averaged around six inches in the Poconos and Berks County, eight inches in the Lehigh Valley and from eight to twelve inches in the Greater Philadelphia Metropolitan Area. Six people died directly from the hurricane - four drownings and two persons were hit by trees. The hurricane also indirectly contributed to the death of about seven other persons. About 40 persons were seriously injured. There were hundreds of…

- Apr 15, 2004Wildfire, Carbon$100,000
National Weather Service narrative
Two families lost their barn and mobile home when a brush fire burned out of control and consumed both structures. The owner was burning a brush pile and the fire moved to the barn which was fully engulfed when firefighters arrived. The mobile home had also started to burn. The fire was declared under control at 1145 a.m. EDT. Gusty north winds were believed to have carried sparks from the brush fire to the barn. Four adults and two children were displaced by the fire. The American Red Cross provided the family with lodging and vouchers. The peak wind gust (from the north) for the day was 32 mph at both the Lehigh Valley and Wilkes-Barre International Airports.
