The Bolt Creek Fire in Washington state intensified over the weekend, growing to 11,277 acres Monday morning as hot, dry weather increased fire activity, officials said.

Containment of the wildfire fell to 7% from around 96% over the weekend, FOX13 Seattle reported.

"Fire weather is again on the rise, and some areas have become more hazardous," Bolt Creek Fire Information said.

A 72-hour fire watch was in place amid unseasonably high temperatures and critically low humidity, officials said.
