A series of strong and wet Pacific storm systems will track through
western Washington this week with sharp rises on the rivers flowing
off the Olympics and Cascades. There is little break between each
system. As a result, several rivers are forecast to reach Action
Stage with Minor flooding possible, especially by Wednesday or
Thursday.
Flooding extent will depend on rainfall rates, temperatures, snow
levels, and total rainfall with each of these weather systems next
week.
Please monitor the latest river forecasts from the National Weather
Service for additional information.
Multiple storms will impact the area through the beginning of this
week with heavy rain and snow levels starting at 6000 feet and
remaining above 4000 feet.
* WHAT...Flooding caused by excessive rainfall continues to be
possible.
* WHERE...A portion of northwest Washington, including the following
county, Mason.
* WHEN...Through late tonight.
* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations.
Low-water crossings may be flooded.
* ADDITIONAL DETAILS...
- Progressively stronger storms earlier this morning will
continue to produce heavy rain in the Olympic Mountains. Two
to four inches of rain are expected through Monday and
another three to six inches Tuesday night into Thursday. With
snow levels above the top of the Skokomish River watershed,
this rain will likely drive the Skokomish river above flood
stage.
