The Upper level airflow will keep the moisture pouring into the Pacific Northwest. The days 1-3 graphic shows a stationary front that  gets pushed southward toward us and a storm system moving toward us from the Southwest.  The graphic for days 3-7 shows then next storm headed our way from the Northwest next Tuesday. We’re still seeing snow accumulations increasing in the mountains. For mountain snow conditions at the local ski areas check out their websites or give them a call. With the potential of significant snowfall and mixed precipitation you’d be wise to judge carefully when and if you need to drive during the next 12 hours or so of this storm.

Signs have been posted along several access areas along the river.
• A Blue-Green Algae Health Advisory remains in effect for Agency Lake. Agency Lake is located just north of Upper Klamath Lake near Klamath Falls along Highway 97 in Klamath County. Water monitoring on the lake has confirmed the presence of high levels of blue-green algae and associated toxins that can be harmful to people and animals. Swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing and power boating, should be avoided in areas where blooms are identified. Although toxins are not absorbed through the skin, contact with cells from a bloom can cause skin irritation and a red, puffy rash in individuals with skin sensitivities, or those who develop rashes easily.
