- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Tuscola County: 0.
- 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.

- 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.

Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

National Weather Service narrative
A non thunderstorm event took place over the state on Wednesday, March 8, 2017, as high winds brought wind gusts in excess of 60 mph! The high winds took out power lines and trees, along with numerous reports of structural damage to buildings. There were also reports of brush fires and tractor-trailers flipped over around the area. Due to the extensive damage, many areas were without power for several days. Approximately 800,000 DTE customers and approximately 300,000 Consumers Energy customers were affected. The highest wind gust reported across Southeast Michigan was 68 mph at both Saginaw and Detroit Metro Airport.
- Jun 21, 1996Flash Flood$6.5 million
- May 25, 2019Flood$4.2 million
National Weather Service narrative
Thunderstorms produced heavy rain, with 1 to 4 inches reported, generally along and north of I-69. Locations across southeast Saginaw and southwest Tuscola counties saw the heaviest rain, just over 4 inches which caused significant flooding, resulting in at least 4.5 million dollars of damage. Numerous roads around Frankenmuth were flooded, but most of the road washouts and damage occurred across the county line in southwest Tuscola county.
- Dec 21, 2013Ice Storm, Tuscola$3.0 million
National Weather Service narrative
A winter storm impacted a large swath of the country from the southern Plains through the Midwest and into the Northeast on the last weekend before Christmas. This storm occurred as a deep upper-level trough over the Desert Southwest lifted northeastward, while a surface low pressure system moved from Texas into the Ohio Valley. This low moved along a very sharp frontal boundary. This front at the surface actually briefly penetrated far southeastern Michigan Friday night. The temperature at Lambertville, on the Ohio border, rose into the mid-50s, while Monroe, just 15 miles away, stayed in the mid-30s. On Saturday, copious Gulf moisture was brought northward ahead of the…

An intense Arctic Front swept through southeast Michigan around Midnight of January 19th, with westerly winds gusting around 60 mph across much of the area during the early morning hours of January 20th. Dozens of trees and power lines were downed across individual counties, leading to power outages in excess of 120,000 DTE customers during the peak of the winds.||Here are some of the higher wind gusts and times reported:||Caro...61 MPH...1214 AM. |Pontiac...60 MPH...301 AM. |Ypsilanti...60 MPH...140 AM. |Flint...59 MPH...247 AM. |Adrian ...55 MPH...128 AM. |Detroit Metro Airport...55 MPH...158 AM. |White Lake...54 MPH...150 AM. |Owosso...53 MPH...1255 AM. |Downtown Detroit…
- Apr 14, 2018Winter Storm, Tuscola$1.0 million
National Weather Service narrative
A large and complex low pressure system impacted the Great Lakes region. Southeast Michigan saw heavy rain, snow, sleet and freezing rain that began on Friday (April 13) and lasted through Sunday (April 15). This system brought 2 main periods of precipitation, with a short break in between on Saturday. Total rainfall of 1 to 2 inches was common in many locations in Southeast Michigan, with 2-3 of snow and sleet north of I-69, and about 1/4 to 1/2 of ice from freezing rain between the I-94 and I-96 corridors. Widespread tree damage and power outages from an combination of the snow, sleet, and freezing rain occurred. In total, DTE and Consumers Energy reported power outages for…
- Nov 17, 2013High Wind, Tuscola$1.0 million
National Weather Service narrative
A powerful low pressure system strengthened and tracked northeast from the western Great Lakes towards James Bay during the afternoon of November 17th through the overnight hours. Southerly winds out ahead of the cold front allowed temperatures to soar into the lower to middle 60s during the afternoon hours across southeast Michigan. A line of thunderstorms developed with the cold front that swept through the area during the evening hours. Several of these storms produced severe wind gusts and wind damage as they moved through the area. Behind the cold front, gradient winds gusted to 55 to 65 mph during the evening and overnight hours, producing additional damage across southeast…
- May 4, 2018High Wind, Tuscola$850,000
National Weather Service narrative
A strong low pressure system tracked through northern Lower Michigan, swinging a strong cold front through southeast Michigan early in the afternoon. Sustained winds ranging between 30 - 40 mph, with frequent gusts in the 45 to 60 mph range, with scattered thunderstorms that developed leading to enhanced winds near 70 MPH. Downed large trees, branches, telephone and power lines were reported across all counties in Southeast Michigan, with around 230,000 customers without power during the peak. In Independence Township, a large tree fell onto a car, killing the 36 year old man inside. Additionally, a postal employee in South Lyon was also seriously hurt when a tree fell on him as…
- Nov 12, 2003High Wind, Tuscola$800,000
National Weather Service narrative
A strong low pressure system moved across the straits on the evening of the 12th, moving into Ontario overnight as it deepened to 974 mb. Strong cold advection and a tight pressure gradient over Lower Michigan produced wind gusts between 50 and 60 MPH across all of Southeast Michigan. In addition, there were even a few wind gusts reported between 60 and 88 mph. The highest wind gust was reported by a spotter in Dexter who recorded an 88 mph gust. An estimated 250,000 customers lost power in southeast Michigan, as widespread trees and power lines were blown down.
