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

- 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.

- Oct 6, 2012Flash Flood$1.8 million
National Weather Service narrative
A temporary dam and de-watering structure was in place alongside the Brown Bridge Dam on the Boardman River. This temporary dam was to assist in drawing down the small lake (Brown Bridge Pond) behind the dam, prior to the permanent removal of Brown Bridge Dam. This temporary dam failed on the morning of the 6th, and by late afternoon, most of the remaining water in Brown Bridge Pond had been released downstream. Within an hour, road closings occurred along Garfield and River Roads, and homes were evacuated along the river between Garfield and Keystone Roads. Eventually, 53 homes were impacted, with varying degrees of damage. Docks, small footbridges, and a number of smaller…
- Mar 2, 2012Heavy Snow, Grand Traverse$600,000
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…
- May 28, 2020Flash Flood$310,000
National Weather Service narrative
Munson Hospital measured 3.12 inches of rain during the day on the 28th. Most of this was dumped in a short period of time, early in the afternoon. This resulted in a small area of flash flooding, in downtown Traverse City and on the near west side. Water rose up to three feet high on some roads and parking lots, and in a few spots the water was higher. Some people were trapped in vehicles and required rescue. Numerous vehicles were heavily damaged. The basement of Munson Hospital flooded. Kids Creek rose out of banks, flooding roads and some buildings.
