Pacific systems bringing moisture to the region on Friday and through the weekend could cause minor flooding in some parts of Southwest Idaho and Southeastern Oregon, according to the National Weather Service.
Small creeks, ditches and poorly draining areas are the places most likely to be affected. River flooding is not expected, though rivers may rise significantly.
Areas burned by wildfires are more susceptible to mud slides, particularly the area burned by the Elk Complex Fire area in Elmore County, according to the Weather Service.
Wednesday was the rainiest day for February so far, with almost a half inch recorded at the Boise Airport.
The total precipitation in February for Boise so far is 1.17 inches about .75 inches more than normal for the whole month. Friday is expected to be another rainy day.
