Storms out of the southwest could bring heavy rains that cause flash flooding in the Boise mountains Monday and Tuesday, according to the National Weather Service.
Scattered thunderstorms are expected to bring rain to the Treasure Valley and may produce heavy rain Tuesday.
The flood watch will be upgraded to a warning if the flooding threat becomes imminent. The area included in the current watch includes: Boise Mountains, Camas Prairie, Upper Weiser River and Central Mountains.
Monsoon moisture coming into Southwest Idaho makes conditions favorable for flash flooding. Areas where wildfires have wiped out trees and brush burn scar areas are more susceptible to flooding. During heavy rain, the public should avoid steep terrain and fast-moving streams.
