Smoke from the Maria Fire burning in Ventura County is now visible from San Luis Obispo.
The fire broke out Thursday evening off of Bradley Road and Solano Verde Drive in Santa Paula and grew quickly.
By Friday morning, CAL FIRE said 8,730 acres had burned and there was no containment on the blaze.
At last check, there were about 7,500 people and 1,800 structures in the mandatory evacuation zone.
Santa Barbara County Fire and CAL FIRE SLO have crews assisting in the firefight.
The smoke prompted the Santa Barbara County Air Pollution Control District to issue an air quality alert until air conditions improve.
Health officials say if people see or smell smoke in the air, “be cautious and use common sense to protect your and your family’s health.”
At the start of the week, health officials in San Luis Obispo County issued an air quality alert due smoke impacting the area from fires burning throughout the state.
