An atmospheric river storm system will move through the region
Tuesday and Wednesday, bringing in 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 6000-7000 feet.
Models show large variability in the forecast, with as much as 8
inches or higher over the Olympics in less than 48 hours. The
northern and central Cascades will also see heavy rainfall during
this period, with up to 4 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 including the Chehalis River.
Forecast models show potential for additional significant
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.
