The Lolo Peak fire has grown to 7,500 acres and pre-evacuation notices remain in effect for a section of Highway 12 west of Lolo.
Fire managers say that with warmer and drier weather expected, the blaze could become more active on Tuesday afternoon, mainly in the Cedar Creek, South Fork of Lolo Creek and Johnny Creek areas.
Helicopters are continuing to drop water and fire retardant to slow the flames, however, the blaze is expected to continue spreading to the west down toward the South Fork of Lolo Creek, according to fire managers.
Ground crews have been testing pumps, hoses and sprinklers to ensure they will be ready to protect homes and hold the fire line if they are needed.
An Evacuation Warning remains in place for the south side of Highway 12 between Fort Fizzle and Elk Meadows Road. This is not an order to evacuate, only a warning so citizens can prepare should evacuations become necessary.
Highway 12 remains open, but drivers are being asked to not stop along the road to view fire activity as it creates a traffic hazard.
A FireWise trailer with the latest information on the Lolo Peak fire remains in place just south of the intersection of Highway 93 and Highway 12 in Lolo. Fire information is also available in front of Lolo Harvest Foods and the Florence-Carlton School.
An information hotline at (406) 273-5433 is available daily from 7 a.m. until 9 p.m.
There are 376 people assigned to fight the lightning sparked fire that's burning 10 miles southwest of Lolo.
