Back-to-Back Pacific Storms to Impact the West Coast; Heavy Snow in the Central Appalachians

Back-to-back powerful Pacific storm systems to impact the Pacific Northwest and northern California through the end of this week with heavy rain, flooding, strong winds, and higher elevation mountain snow. A strong, long-duration atmospheric river will accompany the Pacific storms, bringing excessive rainfall and flash flooding to southwest Oregon and northwest California through the week. Read More >

Overview

The second major winter storm of 2017 arrived late in the weekend, January 8th, and continued through Tuesday, January 10th.

Heavy snow fell over the mountains with snow changing over to rain in several of the valleys as warmer temperatures moved into the area. However, some of the valleys saw strong inversions early on in the storm, before most areas mixed out on Monday, January 9th. Even Telluride, Colorado, elevation 9070 feet, received rain late Sunday and again on Monday!

The abundance of rain and snow fell as a result of a very warm and moist atmospheric river, also known as the "Pineapple Express", stretching from Hawaii all the way to Colorado. Several waves of energy also passed through the area, enhancing the heavy precipitation. Snowfall amounts varied from 1 to 2 feet for the higher mountains with up to 4 feet of snow near Crested Butte! This resulted in a very rare closure for the ski resort on Monday. 

One other event, was an anomalous Ice Storm that severely impacted travel, commerce and educational institutes across the cities of Grand Junction and Durango. You can find a detailed overview of the ice storm here.
