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.
