Urgent winter weather warnings have been issued for parts of California, Nevada, Washington and Oregon. Affected areas include the Greater Lake Tahoe region of California and Nevada, the West Slope Northern Sierra Nevada, and portions of the Cascades in Washington and Oregon, with snow and dangerous conditions expected in these mountainous regions.
