The rain headed our way starting Friday looks to be a half inch or less per day depending what part of the Chehalis Basin you live in. Olympic side is looking at a max accumulation of 4.5 inches over 10 days. Upper Chehalis is 2.5 range. Unless in the mix we get a 2 inch dumper day things should not blow out. From the 22nd to 28th at Porter the river will go from 300 cfs plus to 1029 cfs which sounds like a lot but is not just nice rise. Satsop will go from 165 cfs to to around 700 cfs during same time period.

Keep in mind that the upper Chehalis water takes a couple of days to reach tidewater so that water crest should arrive around the 30th. Water temperatures in tidewater are dropping and boat said 59.9 once this morning.
