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

    When the Mother's Day storm runoff from the Huron Mountains overwhelmed a dike holding back Silver Lake in northwest Marquette County, a wave of water inundated the Dead River basin all the way to Lake Superior in Marquette. A number of roads and bridges were washed out by the flood waters. Officials in the city of Marquette issued a mandatory evacuation order for about 1800 people living north of Wright Street. The Presque Isle Power Plant at the Upper Harbor in Marquette was flooded and shut down for a number of days, resulting in shortages of electricity across western and central Upper Michigan. Flood waters on the Dead River did not subside until May 20th.

  2. Jun 20, 2007Hail$10.0 million
    National Weather Service narrative

    Severe thunderstorms dropped large hail over portions of central Upper Michigan on the afternoon of the 20th. The hardest hit areas were downtown Marquette and Harvey where damage estimates from the storms were reported to be over $60,000,000.

    National Weather Service narrative

    Fairly widespread flooding was observed across a large portion of Marquette County with flooding observed along the Chocolay, Escanaba and Michigamme Rivers. Some of the most severe and longest-duration flooding was along the Michigamme River near Republic and Witch Lake. On April 24th Marquette County officials described extensive and significant flooding damage to 25+ roads and 7+ crossings with damage estimates exceeding $7 million. Marquette County was added to the state of emergency declaration on 4/21 by Governor Whitmer to aid in flood recovery efforts.

  7. Jun 20, 2007Hail$6.0 million

  8. May 20, 2009Wildfire, Marquette$4.0 million
    National Weather Service narrative

    The Black River Falls Wildfire started southwest of Ishpeming in Marquette County on the afternoon of the 20th. The wildfire was ignited when a jack pine tree branch split off the main stem from strong southerly winds and fell across a power line. The wildfire burned 811 acres, destroyed 21 residences and 12 other structures. The fire fighting efforts were led by the Michigan DNR. The wildfire was contained on the 22nd and mop up efforts continued into the 26th. The cost for personnel and equipment to fight the wildfire was estimated at near $100,000. The total damage estimate is unknown at this time but presumed to be in the millions of dollars.
