TULELAKE, Calif. -- Firefighters continue to battle the Antelope Fire in eastern Siskiyou County after it made a significant push to the north and east last week, breaking containment lines. The fire is currently estimated at 145,025 acres with containment dropping again to 63 percent.
Fire officials said that the Antelope Fire was more active Sunday night than on previous nights, as vegetation continues to dry out following last week's minimal rain. Crews worked to patrol fire lines and extinguish any remaining heat overnight. Activity increased where the fire now burns within Lava Beds National Monument.
The Lava Beds park remains largely closed to visitors, with only the eastern entrance and northern road to Gillem Bluff and Captain Jack's stronghold remaining open. Crews are stationed within the park.
On the south and southwestern areas of the fire, within the fire's original footprint around the community of Tennant, fire officials said that only isolated interior heat remains. Crews there continue to conduct mop-up operations whenever new heat sources are found. Similar efforts are underway in the Tamarack area.
Crews have been reinforcing lines along Forest Road 77 east of the Three Sisters area and on the "finger" west of Sheepy Ridge.
"Good work by firefighters in the last few days has resulted in less heat in that area, but crews will continue to patrol and make sure no heat is detectable that could threaten containment," officials said in a Monday update.
Fire officials said that they expect light and variable winds throughout Monday morning, turning to the northwest in the afternoon. Heat will likely increase throughout the day, continuing to dry out vegetation.
"Near-critical conditions are expected Tuesday and Wednesday as another trough approaches the fire area," officials said. "A low-pressure system is expected to enter the area later in the week, bringing first gusty winds with the potential for wetting rain over the weekend."
Evacuations remain in effect for areas southwest of Tulelake and west of Lava Beds. An interactive evacuation map can be accessed here.
