Plumes of smoke may be visible above the southern San Diego area Thursday as state and local firefighters conduct a roughly 70-acre controlled burn near the Otay Lakes.
Officials with Cal Fire said the vegetation-management operation in Rancho Jamul Ecological Reserve would begin around 8 a.m.
San Diego County crews will join state Department of Fish and Wildlife personnel and Cal Fire personnel in the operation, according to Cal Fire.
Authorities frequently schedule controlled burns to reduce the risk of wildfire.
