Lolo, MT -

Fires have burned four homes so far in western Montana, and a state fire official says high temperatures and increasing winds make the blazes likely to keep spreading.

The two fires west of Lolo have burned nearly 8 square miles so far.

The four homes destroyed in the Lolo Creek complex of fires does not include additional structures that also may have burned, but fire officials were not able to verify a total number.

One Hotshot crew, five hand crews, a helicopter and 10 engines and other heavy equipment are battling the fires. Officials have ordered additional resources and are looking to borrow more where they can.

Gov. Steve Bullock has declared a state of emergency for 31 counties across western, northern and southeastern Montana.
