Firefighters have responded to a series of vegetation fires in recent days in San Ysidro, the most recent on Sunday morning.

The first fire was at Willow Road and Calle Primera along southbound Interstate 5 at 7:13 a.m.

The second fire was at the northbound Interstate 805 onramp from East San Ysidro Boulevard.

The fires, according to OnScene.TV, always occur within a short distance of each other and next to freeways.

One of the Sunday fires burned approximately one acre. Crews stopped it from spreading as flames moved near heavy brush.
