242 PM PDT Sat may 19 2018

... A Flood Warning for rain and snowmelt remains in effect until 345
PM PDT Friday for central Okanogan County...

Snowmelt will cause an increase flow from the Conconully reservior
into Salmon Creek through the weekend and into next week. Cooler
temperatures through Sunday may lead to lower flows, but another
warm up next week will increase mountain snow melt. Salmon Creek
will continue to bring a threat of flooding to low lying areas and
driveways along Salmon Creek between Conconully and Okanogan,
including portions of Salmon Creek Road.

Areas that were susceptible to erosion and flooding with high flows
during the first two weeks of may 2018 will remain prone to
additional erosion and flooding issues through next week.

Precautionary/preparedness actions...

Please report flooding to your local law enforcement agency when you
can do so safely.
