Hydrologic Outlook issued December 12 at 2:39PM PST by NWS Seattle WA
ESFSEW A stronger storm will set up along the coast over the weekend with the potential to bring more significant precipitation to the region. Heaviest amounts over the southwestern slopes of the Olympic Mountains may result in potential for the Skokomish River to rise above flood stage Saturday afternoon. Snow levels around 4500 feet Saturday are expected to lower to around 3000 feet early Sunday morning. Ongoing precipitation through early next week could help keep the river levels elevated into Monday. Please monitor the latest river forecasts from the National Weather Service for additional information.

ESFAFG Heavy snow accumulation on river and lake ice can cause overflow to occur on the ice surface but be invisible below the snow. This process can weaken the ice as well as make it more difficult to visually assess ice quality. Those traveling on or going onto ice- covered bodies of water should exercise extra caution.
