 Low moves in tonight and precipitation will continue through tomorrow.  A warm front out ahead of this low is generating the initial round of rain and snow earlier this morning. The cold front will follow tonight as the center of the low comes ashore late tonight.

Colors abound on the warnings map as nearly all areas across the region are under some type of winter advisory or warning.

Areas that will feel the most extreme impact are under a Blizzard Warning. Blizzard warnings already in effect for the Cascades in Northwest Oregon.

Blizzard warned areas could experience winds gusts to 50 mph and snow totals over a foot. Areas within the Winter Storm Warning could end up with up to 14 inches of snow.

Avalanche Concerns

Heavy snow from yesterday in Colorado may lead to avalanche conditions today.

From the Colorado Avalanche Information Center:

FORECAST SNOW FALL SATURDAY AFTERNOON AND NIGHT COULD INCREASE THE
AVALANCHE DANGER TO HIGH ON SUNDAY. AVALANCHE CONDITIONS COULD
BECOME VERY DANGEROUS. LARGE AND DESTRUCTIVE TRIGGERED AND NATURAL
AVALANCHES COULD BE LIKELY. TRAVEL IN OR BELOW AVALANCHE TERRAIN IS

Happy Sunday!
