ESFSEW An atmospheric river impacting the region tonight into Wednesday will bring potentially significant rainfall that could drive some rivers in western Washington into flood stage. There remains uncertainty regarding river flooding mid-week, but the latest rainfall forecast shows 3 to 5 inches of rain over the North Cascades with snow levels as high as 7000 to 8000 feet tonight before briefly lowering back towards 2000 to 3000 feet Wednesday. Forecast models show potential for additional precipitation entering western Washington towards the end of the week, with higher snow levels, which could cause additional river flooding impacts. Please monitor the latest river forecasts from the National Weather Service for additional information.
