The wet weather conditions continue in the Western U.S. and much more precipitation is ahead. Snow totals over the last 24 hours have been above a foot in the mountains from the Rockies to the Sierra.
A rich moisture flow continues from the Pacific Ocean. Many rainfall totals in California were in the 3″ to 6″ range on Tuesday.
Winter Storm Warnings continue for the Cascades, Sierra Nevada, and Tetons. 1 to 2 feet of snow are possible throughout those mountain ranges.
Heavy rain is also a concern, especially in California where the ground is saturated. Flooding alerts remain in effect for coastal areas from south of Seattle to near San Francisco and eastward into interior areas of Nevada & Idaho. Another 6″ of rain could fall in some areas, creating flooding issues.
The Jet Stream will be digging through the Pacific Ocean with a strong core crashing into West through the end of the week. This will support the heavy rain and snow.
A cold front will move toward the Pacific Coast tonight and slowly push ashore through Thursday. Heavy rain will increase tonight from Seattle to San Francisco, with another round of heavy snow from the Cascades to the Sierra.
As the front slowly moves eastward, moisture will stream into the Tetons, Wasatch and Rockies. The rain and snow will gradually diminish into this weekend. A strong wind is expected with the front with gusts above 50 mph possible in mountain peaks and passes.
