Pacific storm systems fueled by an atmospheric river are forecast to bring heavy rain, wet mountain snow, damaging waves and gusty winds to the West Coast and then the wider West well into next week [1]. The first session that can reflect the event is November 16, and this page will be updated after that close.
The Weather Channel reports that a quick-hitting series of Pacific storms will bring rounds of rain, heavy wet mountain snow, potentially damaging waves and gusty winds to the West. It says conditions will come in waves as each storm moves onshore, and that the timings are subject to change [1].
Palisades Tahoe reported about 10 inches at mid-mountain from the first of three snowstorms it expects this week. It said the storm moved through faster than forecast models showed, and that the amount was at the lower end of its forecast [3].
The resort said ridgetop winds increase on Sunday, with gusts up to 50-60+ mph. It said the next storm could push precipitation into the northern Sierra as early as late Sunday afternoon, with showers into Monday [3].
A KCRA headline refers to Northern California storm impacts and chain controls [2].
