Tucson Fire Department will conduct a prescribed burn in the sweetwater wetlands near Prince Road and Interstate 10, west of the highway.
Smoke from the burn will be visible throughout much of Tucson.
“You’ll see this one from across the city," said Barrett Baker, public information officer for TFD. "And it is several hours worth of black smoke depending on how much vegetation there is and when we start the burns.”
Tucson Fire is warning people of the burn so they do not feel the need to call emergency services.
“In this particular case, though, because it’s controlled and we know that it’s happening," Baker said. "We don’t want 911 flooded with those calls.”
The wetlands will be closed for the day, and allergy sufferers are warned that they may have issues due to the smoke.
The prescribed burns are a part of a yearly project, and is accompanied by mosquito abatement.
