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

- 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 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.

- 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).

Mapped by WV GS (2,023), USGS Conterminous (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 warm front surged north during the morning of Friday the 18th, dropping a half inch to an inch of rain. Meanwhile, low pressure extended from southern Ohio on down the entire length of the Ohio River during that afternoon. A southerly wind at the surface, with dew points in the 55 to 60 degree range, fed moisture north from Tennessee and Kentucky. This moisture was advected into the boundary along the Ohio River. Additional rains sank south into western and central West Virginia during the afternoon of the 18th, reaching the Charleston to Sutton corridor around 1500E. The southern edge of the rain lifted a bit further north during the early evening hours, temporarily ending the…
- Feb 16, 2003Ice Storm, Gilmer$500,000
National Weather Service narrative
A severe ice storm occurred across a narrow east to west band of counties. The severe ice continued west, into southeast Ohio and northeast Kentucky. Ice from freezing rain accumulated 1 to 3 inches on power lines and trees. The precipitation then ended as snow on the 17th. The added weight from the ice, broke limbs and snapped the tops off thousands of trees. Other trees were uprooted or left leaning at precarious angles. The fallen trees blocked many roads. Power outages were widespread, and lasted for more than 3 days. Refrigerated frozen foods thawed and spoiled. Phone and water services were also interrupted. The Red Cross opened shelters. One gas station in Ravenswood wired…

National Weather Service narrative
Rains of 2 to 4.2 inches fell from 2200E on the 18th through 1600E on the 19th. A strong inflow of moist air from the southeast, helped enhance these rains. The heaviest rain was over the central and southern mountains, say from the Snowshoe region on through Richwood, Beckley, Mullens, and Elkhorn. Some of the preliminary rain totals were 4.2 inches at Snowshoe, 3.9 inches at Richwood, 3.7 inches at Elkhorn, 3.5 inches at Rosedale, 3.3 inches at Frost and Mullens, 3.1 inches at Webster Springs and Glenville, 2.9 inches at Oak Hill and Beckley.

National Weather Service narrative
Several rounds of showers and thunderstorms formed, along and south a warm frontal boundary. Flooding, gusty winds, hail, and even a funnel cloud were observed. The heaviest rains fell across the upper reaches of the Little Kanawha River basin in central West Virginia, on east, into the central mountains of Webster County. Rains of 1.5 to 3 inches fell from early on the 10th into the evening hours. The upper limit of the rain fell between Sutton and Cowen. One to 2 inches of rain fell in 3 hours during the morning of the 10th across portions of Braxton and Webster Counties. Along Laurel Creek in the Erbacon vicinity of Webster County, an American Red Cross survey found 1 single…

Leading Creek flooded roads and washed out culverts near Alice. Near Troy, a barn and a house had water damage. West of Glenville, Sinking Creek flooded roads. Horn Creek around Cox Mills and the Right Fork of Steer Creek near Shock flooded.

South of a strong frontal zone, rain of 2 to 4 inches fell in a narrow west to east band, from the evening on the 1st, through the afternoon on the 2nd. The heaviest rain appeared across central Jackson County, near Ripley, through northern Roane County, around Spencer and Reedy. The heavy rain continued east into central Calhoun County and southern Gilmer County. A spotter near Normantown of Gilmer County reported 4 inches of rain. An automated rain gauge near Mt Zion of Calhoun County reported 3.7 inches of rain. The cooperative observer at Ripley measured 3.1 inches of rain.
