An atmospheric river will impact the region Tuesday and Wednesday,
bringing potentially significant rainfall that could drive some
rivers in western Washington into flood stage.
There is still a fair amount of uncertainty regarding river flooding
mid-week, but the latest rainfall forecast shows 4 to 7 inches over
the Olympic Peninsula with snow levels as high as 7000 to 8000 feet.
Forecast models show large variability in the forecast, with as much
as 8 inches or higher over the Olympics in less than 36 hours. The
northern and central Cascades will also see heavy rainfall during
this period, with up to 5 inches of liquid forecast through
Wednesday.
The Skokomish River is currently forecast to enter moderate flood
stage by Wednesday, and other area rivers will continue to be
monitored. In addition, urban and small stream flooding will need to
be monitored as well due to potential heavier rain rates Tuesday
night into early Wednesday morning.
Forecast models show potential for additional precipitation entering
western Washington towards the end of the week, which could cause
additional river flooding impacts.
Please monitor the latest river forecasts from the National Weather
Service for additional information.
