A surge of deep monsoonal moisture combined with a slow-moving upper trough will bring periods of heavy showers and thunderstorms across the region. This airmass contains anomalously high moisture content, supporting the potential for excessive rainfall. Flash flooding will be possible, especially in steep terrain, narrow canyons, and near recent burn scars where soils are less able to absorb rainfall. The greatest risk will be Tuesday afternoon through Wednesday evening as repeated rounds of storms move through. * WHAT...Flash flooding caused by excessive rainfall continues to be possible. * WHERE...Portions of Idaho, including the following areas, Boise Mountains, Camas Prairie, Lower Treasure Valley, Owyhee Mountains, Southern Twin Falls County, Southwest Highlands, Upper Treasure Valley, Upper Weiser River, West Central Mountains and Western Magic Valley and Oregon, including the following areas, Baker County, Malheur County and Oregon Lower Treasure Valley. * WHEN...Through Wednesday evening. * IMPACTS...Heavy rainfall could trigger flash flooding or debris flows, especially in and near recent wildfire burn scars. * ADDITIONAL DETAILS... - https://www.weather.gov/safety/flood
