The Line Fire in Southern California has burned over 20,500 acres and is 0% contained.
The wildfire was discovered on Thursday, according to data from InciWeb. It is located in San Bernardino County, about 121 miles northeast of Los Angeles.
High temperatures increased fire activity Sunday night and will continue into Monday, then temperatures will be below normal through Wednesday.
The fire is spreading in a northeasterly direction, according to the Daily Press, part of the USA TODAY Network. However, cooler weather will help temper the flames below sea level.
More than 36,000 buildings, including single-family and multi-family homes, commercial buildings and others, are threatened by the fire and thousands have been forced to evacuate.
The fire also burned areas of the San Bernadino National Forest.
A damage inspection team was ordered and there were 1,855 personnel assigned to fight the fire until more resources arrived from other parts of California.
