Mountain Snows & Flooding Concerns in the West

3 Mar 2017, 2:24 pm

Snow is moving across the mountain ranges in the Western U.S. once again and flooding concerns are in the forecast as well. Flash Flood Watches continue for the San Joaquin Valley due to high water levels in dams and reservoirs. Flood Watches have been issued in Southeast Idaho due to rain in the forecast and warmer temperatures creating a rapid snow melt.

Rain gauges will fill once again this weekend, although totals will not be nearly as robust as they were with earlier storms this winter. Over an inch of rain is possible for many coastal communities. Snowfall totals of 1 to 3 feet are likely by later this weekend for the mountains as Winter Storm Watches and Warnings have been expanded.

In the Cascades, the heaviest snow will occur in Washington. The highest peakswill be approaching 3 feet where Winter Storm Warnings continue. A foot of fresh powder is likely in Oregon.

In the Sierra Nevada Mountains, a Winter Storm Warning remains in effect for the east slopes where more than 2 feet of accumulations will occur. Winter Storm Watches for the rest of the higher elevations across Northern and Central California with 1 to 2 feet possible. A Winter Storm Watch has also been issued for the mountains of Central Idaho where the highest peaks may see 16″ of new snow.

A low pressure center is now moving across the Pacific Northwest, bringing the first round of heavy precipitation to the region. As a cold front slides to the southeast, rain and snow will expand into California and Idaho. A secondary system on Sunday will move along the coast, keeping rain and snow in the forecast through early next week.
