A strong frontal system moving across the area today will continue
to bring moderate to heavy rainfall to western Washington and
possible flooding.
* WHAT...Flooding caused by excessive rainfall continues to be
possible.
* WHERE...Portions of northwest and west central Washington,
including the following counties, in northwest Washington, Grays
Harbor. In west central Washington, King, Lewis, Pierce and
Thurston.
* WHEN...Through Thursday afternoon.
* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations.
* ADDITIONAL DETAILS...
- A rising snow level, moderate to heavy rain, and to a lesser
degree low- to mid-elevation snowmelt will potentially
produce enough runoff to cause minor flooding of some streams
and rivers. The Olympics and Cascades could see an additional
2-4 inches of rain, with some locally higher amounts
possible. With the snow level having risen to above 4000
feet, expect rises on area rivers. However, there is still a
fair amount of uncertainty on which rivers will flood based
on snow level changes, precipitation type and amount, and
snowmelt.
