ESFPQR

A complex area of low pressure offshore will maintain mild and moist
southwest flow into the region through Sunday morning. This will
bring rain, heavy at times, to northwest Oregon and southwest
Washington. Rainfall of 1 to 3 inches is expected across the region,
with 2 to 5 inches over the Willapa Hills, Coast Range and the south
Washington Cascades through Sunday morning. Snow levels will be
rising Friday, and hover at 7000 to 8000 feet through the weekend.
Rain tapers off Sunday into Monday.

With all this rain, and snowmelt from the Coast Range and Cascades,
rivers will be rising. Many small streams and creeks will be running

lying areas and other areas of poor drainage.

In addition to hydrologic impacts, there may also be an elevated
landslide risk. These particularly affects those areas that have
seen significant tree damage due to then recent and strong east
winds.
