This incident is no longer being updated.

The Mercer Fire was ignited by lightning August 22, 2019 in the Pusch Ridge Wilderness north of Melpomene road. The Saguaro Wildland Fire Module and the Mesa Interagency Hotshots worked to secure the fire yesterday and made great progress.

Last night, the fire transitioned from a Type 4 Incident commander down to a Type 5 Incident Commander. All firelines held overnight, and there was no smoke visible this morning.

Today firefighters will hold, patrol and improve firelines, as well as cold-trail and mop-up (identify remaining smoldering fuels, and extinguish them ) as needed.

If fire activity does not increase, resources will eventually be released, and the fire will be placed in monitor status by Santa Catalina District personnel. This will be the final update for the Mercer Fire unless there is a significant change.
