1132 AM PST Sat Dec 6 2025
...Flood Potential Outlook for quick rises on rivers, creeks and
streams in portions of Coos and Douglas counties in Oregon...
A persistent storm track into the Pacific Northwest will bring
periods of rain, some heavy, to Coos and Douglas counties Sunday
through Wednesday. The time frame for heaviest rainfall appears to
be Monday night to Wednesday. Right now, rain amounts of 2 to 4
inches are most likely with the heaviest amounts across northern
Coos County and northern Douglas County along the Lane County
border. Lesser amounts are expected in the Umpqua Basin south of
Roseburg. Heavier rain amounts and flood impacts are more likely
farther north.
Main stem rivers in our area are currently running very low for this
time of year and we are not expecting river flooding. In fact, none
of the local river gauges are currently forecast to even get close
to flood stage. However, water levels could rise quickly, especially
around mid week and around some of the flashier creeks. This could
be dangerous for anyone near the water. Local ponding of water on
roadways could also be a hazard.
Please be aware that forecasts could change. While we are not
anticipating any watches or warnings at this time, watches and
warnings may be issued by the National Weather Service if the
situation worsens. This product will be updated or be allowed to
expire as new information becomes available.
