Summit High School wants all students and parents to be aware of the Winter Storm Warning in effect from 9 p.m. Saturday through 9 p.m. Sunday. Heavy snow is likely in the mountains tonight, and the announcement says to consider the weather when arranging travel to and from prom and after-prom events.
Parents are encouraged to include this in their conversations with students promoting good choices.
According to the National Weather Service advisory, rain and snow showers should change to all snow by mid-evening and become heavier as the storm system moves through, with 1 to 2 inches of snowfall per hour tonight.
Snow should gradually decrease late Sunday with accumulations of 7 to 14 inches in the mountains and 4 to 8 inches in the mountain valleys.
Travel and road conditions will deteriorate quickly, and hazardous winter driving will continue through Sunday.
The service recommends travel only in cases of emergency and advises those who must drive to keep an extra flashlight, food and water in their vehicles.
A strong upper-level low pressure system will move from the Four Corners region tonight to the Colorado-Kansas border by Sunday morning. Most areas of northeast and north-central Colorado will see impact from the storm.
Winds will be west to northwest increasing to 20 to 35 mph with gusts around 50 mph above tree line Sunday. Visibility could drop to a ¼ mile or less in areas of heavy and/or blowing snow.
