SOUTHWEST/SOUTH-CENTRAL COLORADO –  A bit of winter weather returns, and Colorado Department of Transportation (CDOT) maintenance crews are ready. The Colorado State Patrol (CSP) is ready too, and hopeful that motorists will prep their vehicles, know the conditions and drive slowly. “Even when mountain passes are well plowed, there are going to be icy spots and often blowing and drifting snow,” CSP Captain George Dingfelder said. “One of the biggest issues is that people are driving entirely too fast for the conditions.”

Dingfelder also mentions the need to watch for wildlife crossing the highway, which can be particularly hazardous to motorists traveling on snow-packed roads through blowing snow.

“The key is to be on the lookout for wildlife crossing and slow down if you can, but don’t swerve to miss an animal—you could put yourself or other motorists in more danger.”

In the San Luis Valley, motorists should expect snowfall amounts of 4-8" at Monarch Pass (US 50) and 3-6" at Wolf Creek Pass (US 160) and Cumbres/La Manga Pass (SH 17) in the next 36 hours, according to forecasters with Colorado Avalanche Information Center (CAIC). Strong winds at Monarch will contribute to blowing and drifting snow.

“Storm totals by the end of the weekend at Monarch look to be around 10" with little if any additional for the southern passes on Saturday and Sunday,” CAIC Forecaster Mark Mueller reports. “Dry conditions return for the beginning of next week.”

On the other side of the mountain in Silverton, CAIC forecaster Susan Hale reports that skies have cleared for the time being, with snow amounts over the past two days at about 1 to 2 inches south of town and 3 to 4 inches near Red Mountain Pass (US 550). Hale, who provides forecasts for CDOT on US 550’s Coal Bank, Molas and Red Mountain passes, will post her forecast later today as the snow resumes. Motorists should prepare for some winter weather travel and check CDOT’s traveler information site for updates on road conditions (www.cotrip.org).

“We’ll see a lull today, followed by a little better bump in snow later this afternoon and tonight,” Hale said.

For SH 145 over Lizard Head Pass (and areas north), CAIC Forecaster Ann Mellick notes that light snowfall and increasing winds will continue this morning as this system get closer.

“There is a lot of moisture, but the system passes by quickly, which will limit the snow totals,” Mellick reports. “We're generally looking at an additional 4 to 8 inches overnight; and strong westerly winds continue into Friday, which could make for some whiteout conditions tomorrow.”

Mellick expects another pulse of moisture on Saturday night, and light snow on and off through the weekend. A high pressure ridge pushes into Colorado early next week and things will dry through Wednesday.

During any given storm, at least half of CDOT’s crew members will be out at one time, working 24/7 until the storm subsides and roadways and shoulders are cleared. The following information provides details on patrol locations and staff numbers for the department’s two southwest maintenance sections in Durango and Alamosa.

*Maintenance Decision Support System (MDSS), installed on many CDOT plow trucks throughout the state, combines advanced weather prediction, advanced road condition prediction and rules of practice for anti-icing and de-icing to generate road treatment recommendations on a route-by-route basis. The goal of MDSS is to provide more effective use of maintenance resources in order to increase safety, reliability and mobility on roadways. The MDSS system allows CDOT crews to input real-time conditions, including road and ambient temperature, type of snow removal products being used and the application rate. After comparing the information to 15 weather reports, the system will then provide suggested treatments based on the information and models. The system may tell the operator to re-treat the road at a later time, apply different products at different rates or even to continue current procedures. The suggested treatment can then be followed or the operator can override the system.
