Another active weather pattern with a moderately strong atmospheric river is expected in the Cascades, especially the Washington Cascades, beginning Monday and Tuesday. Moderate to heavy rain is possible at the Cascade crest with amounts decreasing away from the crest. By Tuesday night, snow levels drop to around 2500 feet and mountain rain will turn over to snow. Snoqualmie Pass and White Pass have a 45 to 65 percent chance of 2 feet of snow from Tuesday through Thursday night, while Santiam Pass has a 30 percent chance of 2 feet of snow in the same period. This precipitation will lead to river rises and potential additional flooding on the Yakima and Naches Rivers as well as an increased risk of rock and mud slides in areas of steep terrain and near burn scars. However, the transition to snow is expected to keep flooding at lower levels than the past few days. While the Yakima and Naches Rivers are forecast to reach minor flood stage by Tuesday and Wednesday, other rivers in the area are expected to remain below bankfull. Also, windy conditions are expected Tuesday night and Wednesday which may lead to difficult mountain driving conditions. Those living or having travel plans through the Cascades should be prepared for impactful weather next week.

Rising to an impressive elevation of 12,281 feet (3,743 meters), it is the second-highest summit in the state. With a base circumference of approximately 35 miles (56 kilometers), Mount Adams boasts a large size and can be seen from a great distance.

During the winter season, Mount Adams receives heavy snowfall, contributing to its impressive snowpack range. Snow conditions on the mountain vary annually, with an average snow depth ranging from 10 to 20 feet (3 to 6 meters) in the winter months. This abundant snowpack makes Mount Adams a popular destination for backcountry skiing and snowboarding enthusiasts.

This river, along with other smaller creeks, provides a vital water source for the local ecosystem and nearby communities.

Named after President John Adams, Mount Adams has a rich history and is considered a sacred site by Native American tribes in the region.
