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

    National Weather Service narrative

    The third tornado from this parent thunderstorm, and sixth and final tornado of the day, this one was only on the ground momentarily, with a quarter-mile long track. However, this quick touchdown produced substantial damage near Borke Road. One home had its second story ripped off. A nearby mobile home was destroyed, and two barns were significantly damaged. Some livestock (cows and chickens) were killed. Trees in the area were also heavily damaged. Winds were estimated at up to 110 mph, making it an EF2.

A garage and a shed were also destroyed, and there was substantial tree damage. Winds were estimated at 120 mph, making it an EF2.

  3. Mar 2, 2012Heavy Snow, Alpena$100,000
    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…

Widespread downed trees, limbs and powerlines were seen across the County Warning Area, leaving many with power outages that extended for several days.

The Mackinac Bridge was forced to partially close to high profile vehicles for around 12 hours due to winds reported of 82 mph from the mid-span of the bridge.

  7. Oct 26, 2010High Wind, Alpena$20,000
    National Weather Service narrative

    An historically deep low pressure system lifted across Minnesota on the 26th, and passed just north of Lake Superior on the 27th. This storm produced widespread strong to damaging winds across Northern Michigan. Damaging winds kicked in at a few spots by mid-afternoon on the 26th, but the 27th saw the highest winds, with widespread tree and roofing damage, along with power outages. Some vehicles and structures were damaged by falling trees. Power was out for several days at some locations. Peak wind speeds included: 72 mph in Naubinway; 63 mph at Whitefish Point, Manistee Harbor, and Gaylord; 59 mph in Pellston; and 58 mph in Alpena. At one point, the Alpena Airport suspended…
