(UPDATE: 8:22 p.m.): CAL FIRE SLO says the Lopez Fire has now burned 250 acres.
Fire Chief Scott Jalbert says 24 homes were evacuated after the fire broke out Saturday afternoon. However, no homes were lost as CAL FIRE and responding agencies worked to protect the structures from the flames racing through the dry grassland and rugged terrain in the area.
There is no containment at this time. The official cause of the fire is under investigation.
(UPDATE: 7:24 p.m.): One firefighter sustained a minor injury while working on the Lopez Fire, according to CAL FIRE SLO.
Public Information Officer Kirk Sturm says that firefighter was treated and released with a minor injury.
The majority of the active fire Saturday evening is in Federal Forestry land having moved mainly away from homes and campgrounds in the area.
CAL FIRE SLO Chief Scott Jalbert says there are several challenges to fighting the Lopez Fire including the steep and inaccessible terrain in some areas.
Chief Jalbert says the fuels around the Lopez Fire are really dry and the offshore winds were driving the flames uphill.
Jalbert says there are very few recent burn scars, as the area hasn't burned in about 60 years. Nearly 200 acres were burned by early Saturday evening.
Jalbert says fire retardant is around two-thirds of the fire but there is concern for the wind gusts growing and shifting Saturday night to the east/northeast as well as accessing the difficult terrain in the dark.
The fire is burning northeast of Lopez Lake.
Jalbert says he is hopeful the winds will be in their favor Sunday as temperatures start to cool down.
Around 300 firefighters have been assigned to the fire and the San Luis Obispo County Incident Management Team has been activated, according to Jalbert.
Crews will remain on scene overnight.
(UPDATE 5:10 p.m.) - Members of the Elk's Unocal Event Center say they are opening the facility for large animal evacuations. They say they are ready and prepared to take hundreds of animals including cows and horses.

Horse Emergency Evacuation Team (HEAT) is at the event center ready to help.
