A flash flood watch is in effect through much of the day today and into Wednesday for a wide swath of Southwest Idaho as unstable air is expected to sweep into the region from the south. The National Weather Service says the greatest threat of flash flooding will be south of the Snake River Basin in the Camas Prairie and in the Boise Mountains.
The storms could also bring high winds and chances of lightning, which has firefighting officials on alert again.
This past weekend, lightning sparked at least five new fires in the Payette National Forest, pushing smoke into the McCall area from the Ferguson, Greasewood, Fox, Cracker Jack, South Pine, Bald Face and Jeannot fires.
The Devil's Toe Fire, about 25 miles east of Dixie, has burned nearly 150 acres in the Frank Church River of No Return Wilderness.
