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

  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.

  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.

  1. Aug 2, 2015Hail$32.6 million
    National Weather Service narrative

    These were the largest known hailstones in northern lower Michigan history. Hail reached just slightly larger than softballs, a few miles north of West Branch. Immense property destruction resulted, with many, many vehicles considered to be total losses, and roofs and siding dented and damaged. Around 350 structures were damaged in some way, shape, or form.

  2. May 18, 2020Flood$450,000
    National Weather Service narrative

    Widespread areal flooding developed in central and southern Ogemaw County on the 18th. Many creeks and rivers rose out of their banks, including the Rifle River system. Many roads across the county were closed. The Prescott area was especially hard hit, with some property damage due to flooding.

  3. Jun 8, 2008Thunderstorm Wind$190,000
    National Weather Service narrative

    Widespread trees and power lines downed in the West Branch area. Some damage to structures due to falling trees. Considerable roof damage, including a few roofs completely blown off structures.

  4. Jun 12, 2010Flash Flood$150,000
    National Weather Service narrative

    Slow-moving thunderstorms dumped 2.5 to 4.0 inches of rain on the Rose City area on the night of the 11th-12th. The resulting flooding caused damage to 20 basements, and washed out a bridge in the area. Some roads were barricaded or otherwise blocked for several hours to warn off motorists.

  5. Jun 6, 2008Tornado$75,000
    National Weather Service narrative

    The tornado touched down near intersection of M-33 and Sage Lake Road, and lifted about a mile to the northeast. Several farms and residences suffered roof damage, some outbuildings were also damaged, and a number of trees and large limbs were downed.

  6. Aug 28, 2018Tornado$65,000
    National Weather Service narrative

    A brief tornado with maximum winds of 100 mph touched down 4 miles northeast of West Branch, crossing Mud Lake Road. Damage was mostly confined to two homes on the east side of Mud Lake Road.

  7. Mar 2, 2012Heavy Snow, Ogemaw$50,000
    National Weather Service narrative

    One of the highest-impact snowstorms in recent memory pounded Northern Michigan on the night of the 2nd. Low pressure tracked from Missouri, to southern Lower Michigan, and on to eastern Canada, while rapidly strengthening. Precipitation surged northward into the region on the evening of the 2nd. This was primarily snow, except in parts of east central Lower Michigan (especially near Lake Huron), where temperatures were mild enough for rain. Snow wound down on the morning of the 3rd, and though somewhat blustery winds occurred behind the system on the 3rd, blowing snow was limited because the snowfall was so wet.|Snow totals ranged from 6 to 14 inches across most of Northern…

  8. Aug 17, 2017Tornado$45,000
    National Weather Service narrative

    An EF0 tornado developed over George Lake, and crossed Maple Avenue at the north end of the lake before dissipating. Maximum winds were estimated at 80 mph. Damage was done to docks, outbuildings, and the siding of a few homes.

  9. Sep 8, 2015Tornado$40,000
    National Weather Service narrative

    A tornado tracked nearly nine miles across northern Ogemaw County. Damage was sporadic along the path, peaking at EF-1. A number of trees were downed, in some cases snapped off. Several homes and other structures were damaged by downed trees.

  10. Jul 18, 2005Thunderstorm Wind$35,000
    National Weather Service narrative

    Numerous trees and power lines were downed. Several vehicles and homes were struck and damaged by fallen trees. Some minor street flooding also occurred.

  1. Storm Events records before 1996 cover only tornadoes, thunderstorm wind and hail. Damage figures are as reported by the National Weather Service at the time, not adjusted for inflation.
