CENTRAL OREGON -- New fires, lightning holdovers, sparked by a lightning storm that passed through Central Oregon, Sunday, have kept local fire crews busy.

Most were held to less than a tenth of an acre – typically called a single tree fire – with a few that grew larger.

The Shady Grove Fire grew to 15 acres Monday, and a new start 26 miles east of Bend was discovered Tuesday. Crews responded quickly and have held that incident, the Kotzman Fire, to 40 acres.

A Red Flag Warning is in effect for Central Oregon through Saturday morning.
