special announcement Forecast written and compiled by Greg Gagne, approved by Brett Kobernik |

current conditions Spectacular riding and weather conditions reported on Sunday in the 8"-16" new from the Saturday storm. Although the winds were strong during and after frontal passage with wind-drifted snow on all aspects, most reported the new snow and fresh wind drifts as stubborn. Since early Sunday morning winds have died down and are now light out of the North and Northwest. Despite the warm late-February sun, temperatures stayed cool during the day on Sunday and are in the single digits this morning. The warm sun did affect Southerly aspects on Sunday and you will likely find these aspects to be crusted this morning. |
 |
recent activity Sluffing and soft slabs were reported on steeper aspects, as well as wet activity related to warming from the sun (DETAILS.)

description
Although we are expecting wind drifts to be even less sensitive today, I would approach any steep, wind-drifted slope with caution. Although I am not expecting this to be all that widespread a problem, the slide in the Brighton backcountry reminds us that faceted snow may be preserved underneath the recent wind drifts on sheltered northerly aspects at elevations below about 9,500'. |

description
Although the Southerly winds and afternoon clouds may keep a lid on wet activity, the strong late February sun may easily affect Southerly aspects with wet slides and damp roller balls. Pay attention to slopes what you are on as well as what is above you on terrain that faces South through West. |

weather Another nice day on tap ahead of a nice refresher expected overnight. Sunny skies this morning will give way to mid and high level clouds later this afternoon. Temperatures are expected to be in the mid 20's. Winds shifting to the West/Southwest with gusts to 30 mph ahead of a cold trough overnight. Storm totals of 5"-10" are expected by mid-day Tuesday. |
