A brush fire sparked Friday morning near a trail and down a canyon in Oceanside, officials confirmed.
The blaze was reported just before 6:30 a.m. along the 200 block of Stage Coach Road; the Oceanside Fire Department said smoke may be visible from State Route 76 as drivers head out for their morning commute.
About 20 minutes later, officials said fire crews were making good progress on the fire and expected to have it knocked out quickly.
No injuries were reported.
This fire comes as San Diego readies for a heat wave that's expected to last at least five days. The hot, dry conditions will increase the potential for wildfires across the county.
