Couple folks asked how do I get the river information? For a daily forecast I use https://www.nwrfc.noaa.gov/weather/10_day.cgi which is a color chart by rainfall on locations

For the rivers I use https://www.nwrfc.noaa.gov/rfc/ and just put your cursor on the dot and the graph will show location / flows / by day. On the right side of your screen you will see forecast precipitation and click on it then chick 240 hours. You will need to expand your screen to clear the clutter but then just put your cursor on a number / location and where and how much rain by day will show.

Day 3, which is the 24th it is going be ugly in the Olympics with over 3 inches across to the Wynoochee and Satsop head waters. Upper Chehalis is around 2 the 24th. Bottom line is 6 inches or more in 5 days Olympics and Upper Chehalis similar with 4 1/2 inches spread out more over the 5 days. ( not as much on day one ) At Porter the river will crest at about 3800 CFS on the 28th and drop fast. Satsop similar but is forecast to drop below average flows the 28th. Remember it takes 2 days for the Porter crest to make Aberdeen and should be clear or getting clear the 1st.

Now the bay ............... it has got to get some mud out of this but lets hope it clears. Bottom line, big ass storm coming and water should be clear by Oct 1 with tribs dropping..
