    ESFSEW Moderate to heavy rainfall combined with higher snow levels will lead to rises on the rivers flowing off the central and northern Cascades. Several rivers are forecast to reach Action Stage and a few rivers will be close to flood stage. Rivers will continue to run high through the end of the week then recede over the weekend. Please monitor the latest river forecasts from the National Weather Service for additional information.
