Extreme Heat Watch issued June 29 at 1:09AM EDT until July 2 at 8:00PM EDT by NWS Gaylord MI

Effective: Mon June 29, 2026, 1:09 AM
Expires: Mon June 29, 2026, 7:00 PM

* WHAT...Dangerously hot conditions with heat index values between 100 and 108 possible. * WHERE...Alcona, Alpena, Arenac, Cheboygan, Gladwin, Iosco, Montmorency, Ogemaw, Oscoda, and Presque Isle Counties. * WHEN...From Tuesday afternoon through Thursday evening. * IMPACTS...Heat related illnesses increase significantly during extreme heat and high humidity events. * ADDITIONAL DETAILS...Tuesday will likely feature the most extreme conditions for most, with heat indices exceeding 105 degrees. Although mid-week temperatures are dependent on thunderstorm development, prolonged high humidity and limited overnight cooling will lead to compounding heat stress throughout the week.

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Do not leave young children and pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes.

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.
