| Brief Description | Hydrologic Outlook | |
| Detailed Description | ESFPQR An series of frontal systems will bring heavy rainfall to northwest Oregon and southwest Washington through Monday. Heavier rain will begin with the arrival of a front this afternoon, and intensify tonight into Sunday. After a brief lull in precipitation late Sunday, another strong system will bring additional moderate to heavy rainfall on Monday. This will lead to rises on rivers and creeks, especially for rivers draining the Willapa Hills and Oregon Coast Range through Monday. Main stem rivers may be delayed to respond, and flooding may occur beyond this time frame. There is around a 20-30% chance of the Wilson River, the Grays River, and other localized quick responding coastal rivers of reaching minor flood stage by late Sunday or early Monday. More widespread river flooding is not expected, but increases in forecast precipitation amounts could lead to additional rises on area rivers if heavier rainfall stalls over the area for a longer period of time. Heavy rainfall along the Cascades combined with snowmelt will lead to an enhanced risk of landslides. Heavy rainfall may also lead to ponding of water and localized urban flooding, especially in low-lying areas or other poor-drainage areas. Heavy rainfall will also increase the potential for landslides in areas of steep terrain. The probability of debris flows is currently low as rainfall rates are not expected to meet thresholds over areas that have been burned by wildfires over the past few years. Shifts in the forecast storm track can change the outlook and probabilities for river flooding, so be sure to monitor weather.gov/portland for the latest weather updates, as well as any watches, warnings, or advisories that may be issued.
