Until 2025-03-28T16:00:00-07:00 • National Weather Service
ESFPDT Temperatures in the 60s and 70s Wednesday will increase snow melt of the mid and high elevation snow pack. This will be followed by mountain rain Wednesday through Friday. Saturated mountain soils will allow for efficient runoff and will increase water levels on mountain rivers, creeks and streams. The primary concern is the John Day River at Service Creek which is forecast to reach minor flood stage Friday morning through Saturday morning, peaking Friday afternoon. The Naches River at Cliffdell is currently in action stage and is forecast to peak Thursday night before slowly declining to below action stage Tuesday evening. The Yakima River at Umtanum is also currently in action stage and is forecast to peak Thursday evening before dropping below action stage Friday evening. The Grande Ronde River at Troy is forecast to reach action stage this evening and peak Thursday night into Friday morning before dropping below action stage Sunday morning. The Naches River near Naches is forecast to reach action stage Thursday morning and peaking Thursday night before dropping below action stage Saturday morning. The Yakima River at Kiona is forecast to reach action stage Friday morning, peaking Saturday morning before dropping below action stage Sunday night. Several other rivers are forecast to approach but not quite reach action stage. Smaller creeks and streams may also have significant rises but at this time they do not appear to reach levels that would cause flooding. People with activities near creeks and streams should exercise caution as flows will be swift and very cold water can quickly lead to hypothermia if someone were to fall into the water. Those with interests along rivers, creeks and streams should continue to monitor forecasts as there is some uncertainty in the expected water levels. Stay tuned to for the latest forecast updates along with any flood warnings or advisories that may be issued.
