Flood warning for Bighorn Fire area

The rain is both good and bad news.

The arrival of rain brings welcome relief for crews fighting the Bighorn Fire in the Santa Catalina mountains, but the precipitation would also bring danger in the form of flash floods.

The area burned by the fire, known as the burn scar, is more susceptible to flooding because the plants that usually stop that from happening are burned. A fire can also cause the soil to harden, essentially rendering it water resistant, so it sheds rainfall instead of absorbing it.

A flash flood warning was issued by the National Weather Service in Tucson until 8 p.m. Thursday night for the CDO Wash east of Oracle Road, the Catalina Foothills, and Sabino Canyon.

The warning says residents should be aware of “life-threatening” runoff and debris flows from the fire.
