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

Days each year on which a satellite-traced plume of medium or heavy smoke covered the county’s population centre, 2011 to 2025.
  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.

Months each year with a Palmer index of −3 or lower, 1895 to 2025. Twelve means the whole year.
  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.

  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).

    National Weather Service narrative

    A tornado developed about 3.5 miles southeast of Argonne and moved northeast into Florence County. The storm uprooted and snapped hundreds of trees, some of which fell on vacation cabins along the storm's path. The hardest hit area was several miles east of Argonne shortly after the tornado developed. A large part of the roof of a house was removed (DI 2, DOD 6). The tornado continued northeast into Florence County at 7:46 pm CDT (1846 CST). The average width of the tornado was 250 yards.

  2. Jul 8, 2000Flash Flood$154,000
    National Weather Service narrative

    A nearly stationary front across Wisconsin combined with upper air support and abundant moisture to produce a prolonged period of thunderstorms. A few of the storms contained high winds and hail but flooding from heavy rainfall caused the majority of the problems.The heaviest rainfall occurred in an area that extended from southern Vilas county southeast into Manitowoc county. Rainfall totals in this area ranged from 2 to 4 inches for the 24 hour period ending at 6:00 AM CST on the morning of the 8th. Flooding of roads and/or basements was reported in the area from Pelican Lake to Rhinelander (Oneida co.), around Antigo and Deerbrook (Langlade co.), Crandon (Forest co.), Keshena…

  4. Jun 7, 2005Hail$100,000
    National Weather Service narrative

    Thunderstorms developed in the vicinity of a warm front that lifted north through the state during the afternoon and early evening hours. High winds downed trees, power lines and large branches in several locations in central and northeast Wisconsin and there were several reports of large hail. Winds estimated at 80 mph downed numerous trees in western Marathon county and knocked out electrical service to about 2,700 customers around Athens and Stratford. Two supercell storms that moved through southern Forest county caused significant wind damage, dropped large hail and produced a funnel cloud. Three square miles of trees in the Nicolet National Forest were heavily damaged as…

  5. Apr 10, 2011Tornado$50,000
    National Weather Service narrative

    A second tornado formed in Forest County about four miles west of Armstrong Creek at 8:03 pm CDT (1903 CST). The tornado snapped and uprooted trees and damaged two houses. One of the houses sustained significant roof damage (DI 2, DOD 4) as the tornado moved across the area. The average width was 125 yards.

  6. Jun 25, 1998Thunderstorm Wind$20,000
    National Weather Service narrative

    For the second time in less than 24 hours, severe thunderstorms pounded parts of northeast and central Wisconsin, producing damaging winds and hail. The town of Rudolph (Wood co.) was hit again with winds of over 60 mph, which uprooted trees. Clintonville (Waupaca co.) was hit hard as winds uprooted numerous trees on the south side of town. Houses and barns received damage in Clintonville, as did the roof of the town's utilities office.

  7. Nov 10, 1998High Wind, Forest$10,000
    National Weather Service narrative

    An intense area of low pressure moved across the Midwest on November 10, producing very high winds, rain and snow across the region. The low, which tracked from central Iowa to western Lake Superior, resulted in record minimum pressures in Iowa and Minnesota and an unusually widespread high wind event across Wisconsin. The strong winds lasted for much of the day.The high winds caused one fatality and an injury in the area, both in Door county. A 67 year old Door county woman died a week after being blown down by a strong gust of wind. Her head hit the concrete ground, causing the fatal injury.Trees, street signs and power poles were damaged or destroyed by the strong winds across…
