Roscommon County

Every recorded tornado

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

Every storm within 100 miles

1. Tropical storms and hurricanes (34 kt or more, still tropical) at closest approach. Post-tropical remnants with gale-force winds are listed but not counted. Direct: track within 50 miles; near: within 100 miles. Distance is measured to the county boundary for counties and to the city centre for cities, using positions interpolated hourly between HURDAT2 fixes.

Every large fire

1. Large fires mapped by the Monitoring Trends in Burn Severity program since 1984: 1,000 acres or more in the West, 500 or more in the East. Prescribed burns are excluded. Acres here are the part of each perimeter inside this place.

Smoke overhead

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.

2. Mar 2, 2012Heavy Snow, Roscommon$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…

9. Oct 27, 2010High Wind, Roscommon$24,000
   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…

The highest gust recorded was 70mph at Traverse City Cherry Capitol airport. Widespread downed trees, limbs and powerlines were seen across the County Warning Area, leaving many with power outages that extended for several days. Some schools and businesses across the area were forced to close for the day due to power outages. 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.
