Hydrologic Outlook issued December 27 at 2:49PM PST by NWS Seattle WA
ESFSEW Additional frontal systems will bring precipitation to Western Washington at times through the weekend. While precipitation will be much less with the systems today and into this weekend, the lack of much of a break will keep rivers over the Southwest Interior rising into the weekend. The Chehalis River appears to be cresting this afternoon well below flood stage through Thurston and Lewis Counties, but will continue to monitor the Chehalis at Porter in Grays Harbor County as it is still forecast just shy of flood stage this weekend. Please monitor the latest river forecasts from the National Weather
