Central Mountains This is Nick in the Colorado Avalanche Information Center at 4:20 pm, Thursday, March 31, 2005. DISCUSSION The closed low just SE of CO is slowly pulling away. Thus, we'll see a gradual drying trend from the W to E into this evening. A high amplitude ridge will migrate over CO Friday and Saturday bringing clear skies and mild weather. The lower elevations and valleys could be pretty warm. The next storm system will move into the Pacific NW Saturday. The ridge will force that storm N of us, but the N&C mtns could see some clouds Saturday into Sunday. The forecast details: Thur night: Partly cloudy, isolated showers possible early. Winds NNE/5-15 few G20 possible above TL. Lows 5-15. Friday: Clear skies. Winds NW/5-15 some G20 possible above TL. Highs 23-33. Lows 8-18. Saturday: Sunny. Winds WSW/5-15 few G20 possible above TL. Highs 26-36. SNOWPACK Surprisingly, few avalanches have been reported today. CDOT control work on Grand Mesa produced surface only sloughing due to no weak layer (anticipated). Control work on Loveland Pass got 6 slides to run, one broke quite deep and covered the road with 10' of debris. Only a couple of slides were reported from Telluride ski area. Telluride Helitrax flew in their area and got two slides with control work on the Ophir valley. One fractured about 6' deep and ran some 800' vertical on a NNE aspect. With the amount of recent snow and winds (T-ride got 20.5" for the storm) they said they saw surprisingly little natural avalanche activity while flying around. Avalanche control work was also done on Red Mtn Pass but data from there has yet to come in. Some 30" of snow was reported from backcountry skiers in Yankee Boy Basin, SW of Ouray, with several natural avalanches they spotted and heard in that area yesterday afternoon. There were only a handful of small slides with control work at Snowmass yesterday. It's still possible for an avalanche to break down into weak, deeper layers, especially if a shallow slab is released and steps down. Backcountry travelers should use extra caution on any drifted terrain at this time that is 35 degrees or steeper. If you like to take risks and are going to challenge the steeper slopes make sure you are with avalanche-rescue-qualified people, that everyone is carrying the proper equipment, and that only one person is exposed on the slope at a time. Don't just ask yourself "could this slope slide" but also "where will it take me if it does slide." Severe injuries can be sustained if you are carried into rocks or trees. And even a small avalanche can bury you deeply if you are carried into a gulley. With recent new snow, and much warmer temperatures in the next 48 hours, the danger for wet snow avalanches will be on the increase. Areas below TL, and sunny aspects near and above TL around rock outcrops will be the biggest concern. The backcountry avalanche danger is currently rated: C mtns: Near and above treeline the danger is CONSIDERABLE on slopes facing N-E-SW where recent drifting has occurred. On other aspects the danger is MODERATE on steep, recently drifted areas. Below treeline the danger is MODERATE, but with pockets of CONSIDERABLE developing in the afternoon on sunny aspects. NLogan
