* WHAT...Heavy snow expected above 4000 feet. Total snow
accumulations of 8 to 20 inches. Winds gusting as high as 60
mph.
* WHERE...In Oregon, Northern Blue Mountains of Oregon. In
Washington, Northwest Blue Mountains.
* WHEN...From 10 PM this evening to 4 PM PST Thursday.

blowing snow could significantly reduce visibility. The
hazardous conditions could impact the morning or evening
commute. Gusty winds could bring down tree branches.
* ADDITIONAL DETAILS...Periods of heavy snow will impact the
northern Blues tonight into Wednesday morning, and again late
Wednesday evening through Thursday. Rain and a rain to snow
mix will occur during the day Wednesday. Strong gusty winds
will also produce patchy blowing snow at times late Wednesday
into Thursday.
A strong frontal system will move across the area today and into
tonight, bringing a round of 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 and Mason. 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 3 to 5 inches
of rain. The snow level will rise Wednesday to 4500 feet.
Based on the degree of snow level changes, it's relation to
precipitation, and the amount of precipitation and snowmelt
makes for a fair amount of uncertainty on what, if any,
rivers will flood. The exception is the Skokomish River which
is highly likely to exceed flood stage and possibly Moderate
Flood.
