There is the potential of heavy rainfall across eastern utah and western colorado monday afternoon through wednesday as deep monsoonal moisture spreads over the area. The heaviest and most widespread showers will be on tuesday afternoon as a disturbance passes over the area. Storms will be slow moving so localized flooding will be possible. Normally dry washes and creek beds could flow and create running water across low-lying roads. Localized debris flows or falling rocks will also be possible in steep terrain areas susceptible to runoff problems.
