HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE SEATTLE WA
328 PM PDT Wed Oct 18 2017

...Heavy rainfall will Give a Threat of Flooding to Many Western
Washington Rivers Saturday night and Sunday...

A period of significant rainfall is forecast by weather prediction
models from later Saturday through Sunday. This rainfall may
produce minor flooding on area rivers starting Saturday night and
continuing through Sunday or Sunday night.

While it is difficult at this time to pinpoint exactly where and
when the heaviest rainfall and highest threat for flooding will
occur, it appears that the greatest threat will be over the
southern half of Western Washington Saturday night and Sunday.

Please continue to monitor latest forecasts since conditions can
change.
