ESFPDT
Temperatures in the 60s and 70s through Wednesday will increase snow
melt of the mid and high elevation snow pack. This will be followed
by mountain rain Wednesday night 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 Thursday morning through Friday
afternoon, peaking early Friday morning. The Grande Ronde River at
Troy and the Naches River at Cliffdell and Naches are expected to
reach action stage Wednesday afternoon through at least Friday
morning but have a low probability of reaching minor flood stage.
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.

Warmer temperatures will lead to snowmelt, causing rises on
rivers, creeks, and streams across southeast Oregon through
midweek. Saturated soils in some areas will increase runoff.
Those with interests along rivers, creeks and streams should
continue to monitor the forecast as there is some uncertainty in
how much response the lower elevation rivers, creeks and streams
will see. Stay tuned to the forecast for the latest updates, along
with any warnings or advisories that may be issued.
