The next weather is coming in as northwesterly flow brings in a series of moist ripples and impulses starting in the late afternoon. Scattered light snow will start along the Wyoming border and spill southwards overnight. Light snow will reach the northern San Juans by dawn. All the northern and central zones will see a few inches of accumulation overnight and Friday morning. The jet stream sags southwards overnight, gusts upwards of 80 mph are possible in the northern and central mountains. Snowfall eases Friday afternoon, but light snow will continue into Saturday morning. It looks like the ripples and impulses will continue through the weekend, with 4-8 inches every 12 hours in favored locations. Plenty of moisture and good orographics means the snow will add up.

Because this comes so quickly after our last big storm at the beginning of the week, the new loading will be enough to keep natural avalanches possible on most aspects and elevations. Wind loaded slopes facing North through East through South near and above treeline will see the most avalanche activity. Occasional periods of good visibility since Tuesday have given us a good look at recent avalanche events. The Castle Creek valley had the largest avalanche cycle. Avalanches on the Highlands Ridge occurred on NE, E, and SE aspects above and below treeline. These ran up to 2500 vertical feet. Around Ashcroft, 2 larger avalanches were observed on the E and SE aspects of Monument Peak. A smaller avalanche was observed here on a cross loaded W aspect of Richmond Ridge as well. Yesterday an observer on McClure pass noted a natural avalanche below treeline in a wind loaded N facing slope off of Huntsman's Ridge, and another slide was spotted Thursday in Raspberry Creek on a SE aspect below treeline. Most of the avalanches observed have one thing in common, they are running in wind loaded or cross loaded slopes on a variety of aspects and elevations. Very strong winds in the big storm drifted snow further down slopes than usual, forming slabs lower in paths. Below treeline areas have some slab formation as well, and only the deepest, darkest, sheltered corners were spared in the last wind storm. Once initiated, fractures on stiff, dense wind slabs have the potential to travel long distances. These wind slabs may give you clues to their unstable nature right now. Numerous reports of whumphing and some shooting cracks have been reported to the office in the last 2 days. These 2 clues, along with recent avalanche events, should make you think carefully about travel on steeper slopes at this time. The newest will disguise the slabs left behind from last weekend's windstorm. Dig down and inspect what you are traveling on before committing to slopes steep enough to slide. Backcountry travel at this time will require advanced avalanche skills to stay safe. Your eye for terrain selection is very important. The snowpack is unstable in most areas but choosing safer terrain will help you avoid these problems. Avalanche Danger The avalanche danger in the Aspen zone is CONSIDERABLE on all aspects and elevations. Look for locally higher danger in the southwest part of the zone, where more snow accumulated on Wednesday. Slopes near and above treeline facing N-E-S continue to pick up more wind deposited snow. This increasing load will make them especially tender. The CAIC Aspen office needs your backcountry avalanche, weather, and snowpack observations! During storm cycles like this, these observations are very valuable and our forecaster's legs and eyes can only cover so much terrain in one day! You can help out by emailing us at caic@qwest.net with anything you see out there today.

The fresh snow will disguise the slabs left behind from last weekend's windstorm. Remember that just because you cannot see the buried windslabs, doesn't mean you cannot trigger them. Heavily loaded, cross loaded and drifted lee areas on north, through east, through south facing aspects abound. Strong winds drifted snow further down slopes than usual as well as into below treeline areas. The slabs may be sensitive to human triggering. Be especially aware of loaded easterly aspects near and above treeline, as yet another layer has been added to the snowpack. Observers report a couple fresh avalanches in these new windslabs on easterly aspects near Willow Creek Pass (western edge of the zone). Slides triggered over the last week are a reminder that we have both deep and hard slab problems, neither of which will go away any time soon. The most recent avalanche reported occurred on Tuesday when highway crews triggered slides with mitigation work. At least one very hard slab released well below treeline on a north facing aspect. Forecasters noted that it came down largely in one big piece. Remember that hard slabs have a nasty habit of luring unwary backcountry travelers a ways onto slopes before releasing. Dig down and inspect what you are traveling on before committing to slopes steep enough to slide. Recent winds have also deposited some very thick slabs. One such slab was triggered last Saturday on a short, steep north facing slope between Second and First Creeks, north of Berthoud Pass. At its deepest point, the crown was 22 feet deep. It may be difficult to trigger a monster like that, but once initiated, these slides can be very large, dangerous and destructive. Remember that deep slides are often triggered from shallower, weaker areas on the slope. Smaller slides may step down, triggering older weak layers as well. New snow combined with blowing and drifting snow over the past days has added new layers to the already questionable stack. Look for obvious signs of instability including recent avalanching, shooting cracks, collapsing and strong over weak stratigraphy. Expect to find increasingly sensitive windslabs and drifts and approach all exposed slopes steeper than 30 degrees with caution. Avalanche Danger Reactive wind slabs in the upper snowpack and deep slab instabilities continue to be the main concerns.The avalanche danger in the Front Range is CONSIDERABLE on north, northeast, east, southeast and south aspects near and above treeline. Human triggered avalanches are probable on steep wind loaded slopes. Below treeline on north, northeast, east, southeast and south aspects the danger is MODERATE with pockets of CONSIDERABLE danger. You will find the pockets on steep slopes that are open or lightly treed, where windslabs formed early in the week. The danger is MODERATE on southwest, west, and northwest aspects at all elevations. Grand Mesa ========== Current Keywords: cross loaded, drift, drifts, orographics, slabs, windloaded, windslabs, Mountain Weather and Avalanche Forecast for the Grand Mesa Zone Forecast Issued on 1/31/2008 4:21:29 PM Forecaster: Spencer Logan Weather Synopsis Blue skies will give was to snow tonight.

South to west winds were strong enough to drift snow past the usual starting zones and load it owe on slopes than is usual. Windslabs formed on north to east to southeast aspects. Control work triggered several avalanches in the recent windslabs. All were in in the upper layers of the snowpack and did not step down to lower weaknesses. Watch for sensitive drifts and cross loaded areas. Weak layers existed at the old snow surface prior to the storm, so slides will likely continue to occur at the old/recent snow interface. Use caution on or under windloaded terrain in the backcountry today. Avalanche Danger We have insufficient data to issue a danger rating for the Grand Mesa Zone.

Control work triggered slides on almost every aspects at all elevations. Only a few triggered slides have been reported since, but they are still occurring. In the backcountry, avalanches ran on a variety of aspects and elevations throughout the range. Many paths ran during the storm and subsequently drifted back in. Most of the avalanches ran in the storm layers, a few feet deep, but there were several crowns up to 6 feet deep. Additional slabs formed Thursday. Winds shifted from the southwest to northwest to north, loading the tail end of the storm onto most aspects. It's yet another slab stacked on an already unstable pile. Friday brings light snow, but continued winds from the southwest. The load on the snowpack will not increase dramatically, but neither will it ease. Be aware that new snow will disguise recently deposited wind slabs, so dig down to get a feel for what you are traveling on before committing to slopes steep enough to slide. Once initiated, fractures on stiff, cohesive windslabs have the potential to propagate over long distances. As you travel in the backcountry, look for obvious signs of instability including recent avalanching, shooting cracks, collapsing and hollow sounds. Choose your terrain very wisely, only expose one rider at a time, and have escape routes planned Avalanche Danger The avalanche danger is HIGH on north, northeast, east, southeast and south aspects near and above treeline - unstable slabs, as well as natural and human-triggered avalanches are likely on these aspects and elevations. The danger is CONSIDERABLE on other aspects. [57]Please let us know if you see any avalanche activity or experienced signs of instability.

Underneath the new slabs, the snowpack is slowly adjusting to the big load is received at the beginning of the week. Recent activity is a reminder. On Tuesday, snowcats triggered several slides north of Durango Mountain. Of particular note, one slide on an east aspect was remotely triggered from a half a mile away. There was a report of an avalanche involving just recent snow along Highway 550, on a southeast aspect below treeline. Control work along the Highway 160 corridor triggered surprisingly few slides given the amount of snow and wind. However, one triggered slide had a section of crown that measured up to 10 feet deep, though the average crown depth was around 3 feet. This is a reminder of how quickly and deeply wind can load. In many locations the recent slabs sit atop buried surface hoar, facets or crusts. These layers make a poor foundation. The main avalanche problem is these recent slabs, and how well they bonded to the underlying snow. Evaluate that bond carefully before you venture onto steep slopes. Avalanche Danger The avalanche danger is CONSIDERABLE on all slopes near and above treeline. Unstable slabs are probable on steep, wind loaded slopes. Below treeline the danger is MODERATE. Human triggered avalanches are possible, and steep slopes where the trees are open enough to allow windloading are the most suspect. [57]Please let us know if you see any avalanche activity or experienced signs of instability.

While we do not know exactly how much snow accumulated in the mountains, we do know that strong winds battered the range, redistributing any snow that did fall. Expect north through east through southerly aspects to be loaded and drifted. The Sangres have a relatively shallow snowpack, capped by a variety of dense windslabs. Carefully examine the structure and stratigraphy of the snowpack before committing to slopes over 30 degrees. As always, we really like to get observations, even if it is just cloud cover and new snow from the valley floors. Avalanche Danger We have insufficient information to issue an avalanche danger for the Sangre De Christo zone. Carefully evaluate steep wind loaded slopes and be very aware of changing conditions.

Winds were moderate with strong gusts coming from the west-northwest. You will find soft slabs on below ridges and on cross loaded terrain features facing north, northeast, east, southeast and south. Earlier in the week strong to moderate winds have come in from the south, south west, west, north west and north. Slabs formed on most aspects further down slopes than usual and below treeline, creating slabs ripe for triggering. To find the extent of the slab coverage, you will need to use your shovel to dig and your probe pole to feel them. The more you use your shovel and probe to get valuable snowpack information, the less likely you are to need them for rescue. If you choose to be in the backcountry today, choose your terrain wisely. Avoid slopes steeper than 34 degrees, ride one at a time and have your escape route planned. Human triggered avalanches will remain probable on all aspects and elevations. More snow and wind is in the forecast through the weekend, so do not expect the avalanche danger to decrease. Stay tuned! A natural avalanche cycle probably ran during the last storm, though we have not been able to confirm this. Please let us know what kind of conditions you are experiencing out there.

The snowy streak will resume Thursday night. The relatively slow new snow loading is a generally good thing for the snowpack, not stressing it too much at one time. Unfortunately, the winds will be back to the higher elevations on Friday, increasing the load in the north through east to south aspects. Strong southwest winds during the last storm transported a good deal of snow, especially above 9000 feet. The winds created fresh slabs in exposed areas on north through southeast aspects. Releasing a recent wind slab on a steep, exposed north, northeast, east, or southeast slope is the primary avalanche concern today. Watch for sluffing in the new snow as well. Observers did report some interesting slides along Highway 160. The slides were below 8000 feet, on west to northwest aspects, broke 2 to 3 feet deep and propagated several hundred feet wide. Cool--more proof that unusual storms bring unusual avalanches. Avalanche Danger The avalanche danger in the Steamboat Zone is CONSIDERABLE on north, northeast, east, southeast and south aspects near and above treeline. On other aspcets andf below treeline the danger is MODERATE. Human triggered slides are possible to probable today. If you have any observations or data to share, please send them to [57]caic@qwest.net.

The largest was in the Peak 5 cirque, a mostly easterly aspect above treeline. The slide was about 4 feet deep, 200 feet wide, and ran over 500 vertical feet. Another slide ran off Peak 6.5, smaller but similar in depth. There was a 3 hour period of intense windloading Thursday morning in the 10 Mile, with very sensitive hard slabs formed over several inches of powder. One sizeable slide was triggered remotely. The hard slabs formed on southeast aspects near treeline, an unusual loading pattern. Observers north of Vail Pass saw no fresh avalanche activity, even with binoculars and clear visibility. They noted that the snowpack was more stable on the western side of the Zone. Mid-week snow accumulations ranged from 3 to 10 inches. Winds were moderate with strong gusts coming from the west-northwest. You will find soft slabs on below ridges and on cross loaded terrain features facing north, northeast, east, southeast and south. Earlier in the week, strong to moderate winds have come in from the south, southwest, west, northwest and north.
