Air Quality Alert issued July 25 at 7:34AM EDT by NWS Gaylord MI

Non-Weather Emergency Message. Not sent to IPAWS.

Effective: Fri July 25, 2025, 7:34 AM
Expires: Sat July 26, 2025, 1:00 AM

The Michigan Department of Environmental Quality has issued an Air Quality Advisory for Friday July 25, for elevated levels of fine particulates (PM2.5). Pollutants are expected to be in the Unhealthy for Sensitive Groups range. The alert is in effect for the following Michigan Counties, Roscommon, Charlevoix, Missaukee, Beaver Island and surrounding islands, Wexford, Manistee, Mackinac Island/Bois Blanc Island, Emmet, Iosco, Ogemaw, Presque Isle, Cheboygan, Alcona, Eastern Mackinac, Western Mackinac, Montmorency, Otsego, Southeast Chippewa, Antrim, Central Chippewa, Leelanau, Arenac, Western Chippewa, Kalkaska, Grand Traverse, Benzie, Alpena, Oscoda, Crawford, and Gladwin. Smoke from Canadian wildfires will move over the area through this morning, and continue into central lower Michigan through the day. As smoke moves in, PM2.5 concentrations are anticipated to increase into the Unhealthy for Sensitive Groups (USG) range. There is a possibility that hourly levels reach the Unhealthy (red AQI) range for a short period of time. It is recommended that, when possible, you avoid strenuous outdoor activities, especially those with heart disease and respiratory diseases such as asthma. Monitor for symptoms such as wheezing, coughing, chest tightness, dizziness, or burning in nose, throat, and eyes. Reduce or eliminate activities that contribute to air pollution, such as outdoor burning, and use of residential wood burning devices. Keep windows closed overnight to prevent smoke from getting indoors and, if possible, run central air conditioning with MERV-13 or higher rated filters.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
