SOUTHWEST COLORADO – A storm is heading into SW Colorado and CDOT Region 5 maintenance crews are well prepared. While avalanche danger will remain low, the forecasters with the Colorado Avalanche Information Center are calling for a strong southwest flow that will increase throughout western Colorado this afternoon. They expect the moisture and cold front to arrive around midnight with snow starting to fall above 8,000 feet, starting in the San Juan Mountains and quickly spreading north and east into Wednesday morning.  

As colder air pushes into the mountains Wednesday the snow levels will drop into the valleys, according to the CAIC. Storm totals could be around a foot and half in the southern mountains, with clearing skies and warmer temperatures heading into the weekend.

This is what the CAIC is forecasting for SW Colorado:

CO 17 Cumbres/La Manga Passes – 0-2” Tuesday; 3-6” Tuesday Night; 6-8” Wednesday
US 50 Monarch Pass:  0” Tuesday; 0-2” Tuesday Night; 2-6” Wednesday
CO 145 Lizard Head Pass:  0” Tuesday; 2-5” Tuesday Night; 4-7” Wednesday
US 160 Wolf Creek Pass:  0-2” Tuesday; 3-6” Tuesday Night; 6-8” Wednesday
US 550 Passes (Coal Bank, Molas, Red Mountain):  3-5” Tuesday Night; 4-7” Wednesday; 1-3” Wednesday Night (at the time of this press release, this more recent report for this corridor extends into Wednesday night)

“Fall storm conditions usually mean slicker roads because the pavement is still warm and that can make for more driving challenges,” said Greg Stacy, superintendent for CDOT’s Maintenance Section 3, headquartered in Durango. “Don’t get caught unprepared. Now is the time to get snow tires on and make sure your wipers are working and fluids are topped up in your vehicle.”

Stacy also cautions motorists in the valley that, even with a little bit of moisture, bridges can ice up quickly. Morning and evening commuters, in particular, should drive with extra care.

During a winter storm, CDOT maintenance crews are on standby for round-the-clock patrol shifts. Maintenance area crews (see Area and Patrol details, below) are out on 24-hour operation—typically on rotating 12-hour shifts—until they reach dry road conditions. This means that during a storm, at least half the crew members on each patrol are out at any given time, some overlapping their shifts to keep coverage consistent. And, when warranted, avalanche control crews are working together with CAIC forecasters to trigger avalanches before they can run naturally.

“We want to remind truckers to have their chains ready; chances are, you will run into snow-packed conditions with the chain law in effect,” said David Vialpando, superintendent for CDOT’s Maintenance Section 7, headquartered in Alamosa. “We will see most of the snowfall on our mountain passes. Keep your speeds low, particularly on steep grades.”

The following is a summary of Maintenance Sections, Areas and Patrols in CDOT’s Region 5.

Operations for the Durango Maintenance Section are divided into three Maintenance Areas—Durango, Cortez and Ridgway—each with numerous patrol crews within. Here are the details: 

CDOT MAINTENANCE SECTION 3 – HEADQUARTERED DURANGO

The entire Durango Maintenance Section (also see individual maintenance areas, below) has 106 maintenance workers and 107 pieces of snow removal and avalanche control equipment. Thirteen trucks are equipped with liquid deicer applicator tanks. Other plow trucks will carry sand/salt for providing traction or, at optimum temperatures, sand pre-wetted with liquid deicer for traction and effective ice-melting. Durango maintenance crews take care of 1,750 lane-miles (the combined lengths of each lane on every highway in the section), including five mountain passes. Total 2015/16 budget:  $4,146,533.

NOTE:  Each Maintenance Area detailed below has special crews that additional work and/or avalanche control missions (in coordination with the Colorado Avalanche Information Center) on four mountain passes:  US 550 Coal Bank, Molas and Red Mountain passes and SH 145 Lizard Head Pass (US 160 Wolf Creek Pass is maintained by Alamosa crews). Crews from both Maintenance Sections—Durango and Alamosa—assist one another with man-power and equipment during storms, as necessary.

*Maintenance Decision Support System (MDSS), installed on many CDOT plow trucks throughout the state, combines advanced weather and 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.

WINTER TRAVEL TIPS:

  • Log on to CDOT’s Winter Driving web page at:  https://www.codot.gov/travel/winter-driving for road conditions winter driving tips and other information; or for I-70 West Mountain Corridor travel, go here: http://goi70.com/.

  • Be sure you have good snow tires. How do you know if you need new snow tires? Insert a quarter into the tire tread upside down, with Washington’s head going in first; if the top of George’s head is covered by the tread, your tires are OK (do this test in multiple points around each tire.) If the top of his head is visible at any point, you need new tires.

  • Always keep the top half of your gas tank full. It can give you better traction and gives you a bigger margin of error if you get stuck and have to keep the engine running periodically to keep warm.

  • If you are stuck in a serious storm do not leave your car. Run the engine periodically and wait for help.

  • Carry blankets, water, a flashlight, a shovel, some nutrition bars or other food for sustenance. Winterize your vehicle's safety kit by including extra blankets, sand to help gain traction in the event you become stuck on ice or snow, jumper cables, an ice scraper and lock deicer.

  • Remember that 4-wheel drive does not mean 4-wheel stop. A 4-wheel drive vehicle will not stop any better in icy conditions, especially if you have inadequate snow tires.

  • Know the chain laws. Chain restrictions in Colorado are most often put into effect for commercial vehicles (semi-trailer trucks) but can also affect passenger vehicles (always check conditions and chain law restrictions on www.cotrip.org before heading out).

  • Drive for the conditions. In poor visibility or even whiteout conditions, don't drive faster than you can see ahead. High speeds in poor or no visibility can lead to large chain reaction accidents.

  • In addition to these winter driving tips, CDOT reminds all motorists to respect winter weather, conduct a pre-trip inspection of your vehicle, and leave extra space between your automobile and others on the road (including plow trucks). Of course, always buckle up!

SNOW REMOVAL PRODUCTS:

  • Magnesium Chloride:  In solutions that utilize up to 30 percent magnesium chloride, this product is effective for pavement surface temperatures down to 16 degrees Fahrenheit.

  • Cold Temperature Modified Magnesium Chloride:  In solutions that utilize up to 27 percent magnesium chloride, this product is used when surface temperatures fall below approximately 15 degrees Fahrenheit. These products have a corn-processed byproduct additive that greatly lowers the freezing point of magnesium chloride.

  • Ice Slicer:  This is a solid product made up of mainly sodium chloride; it also contains small amounts of other materials making it more effective at lower temperatures than pure sodium chloride.
