More crews are being brought in from North Carolina and Georgia to help fight a 5,000 acre wild fire in the Mark Twain National Forest. The two, twenty-person crews are expected to arrive late tonight to join more than 40 other firefighters who have been battling the blaze since Tuesday.

The Forest Service says so far, no homes are threatened. Rainfall overnight helped suppress the flames, but the outlook for the next few days is dry.

Arson is the suspected cause of the fires.
