ESFSEW An atmospheric river will impact the region Tuesday and Wednesday, bringing potentially significant rainfall that could drive some rivers in western Washington into flood stage. There is still a fair amount of uncertainty regarding river flooding mid-week, but the latest rainfall forecast shows 3 to 5 inches over the Olympic Peninsula with snow levels as high as 7000 to 8000 feet. The northern and central Cascades will also see heavy rainfall during this period, with up to 4 inches of liquid forecast through Wednesday. The Skokomish River is currently forecast to enter moderate flood stage by Wednesday, and other area rivers will continue to be monitored. In addition, urban and small stream flooding will need to be monitored as well due to potential heavier rain rates Tuesday night into early Wednesday morning. Forecast models show potential for additional precipitation entering western Washington towards the end of the week, which could cause additional river flooding impacts. Please monitor the latest river forecasts from the National Weather Service for additional information.
