10:19 a.m., Sunday, January 5, 2003 Tuckerman Ravine has LOW AND MODERATE avalanche danger. Hillmans Highway, The Lower Snowfield, and the Little Headwall have Low avalanche danger. Natural avalanches are very unlikely and human triggerd avalanches are unlikely EXCEPT IN ISOLATED POCKETS. Normal caution is advised. All other areas in Tuckerman have Moderate avalanche danger. Natural avalanches are unlikely and human triggered avalanches are possible. Use caution in steeper terrain. Huntington Ravine has MODERATE avalanche danger. Natural avalanches are unlikely and human triggered avalanches are possible on steep snow cover open slopes and gullies. Use caution in steeper terrain. We have had a very unusual set of weather conditions during this past storm which has given us atypical avalanche danger. Hermit Lake picked up another 6 inches which has brought the total storm amount to 12 inches including settlement. The storm began with SE winds and hung from the E and ENE for the majority of the snowfall with high winds maxing out in the 80-85 mph range. Winds moved up to the NE last night and stalled there occasionally moving back to the ENE. Speeds remained light in the 20-30 mph range. Usually winds slowly creep around to our prevailing winds from the NW or W. This is not forecasted to occur. Winds are expected to slowly shift back down through the E and sit back out of the SE. It's a very strange set of weather events. So the significant loading we were expecting late yesterday and last night did not occur. However E and NE winds did cross load gullies and snowfields with either a Northern or Southern aspect. So several areas of concern are the northern gullies in Huntington, the top of gullies from Lion Head to high up past the Lip here in Tuckerman. This includes Right Gully and the Sluice. Be aware that these are not the only locations of instability. NE winds have also cross loaded the southern aspects near the top of the Chute and Left Gully. There is very little old surface in Huntington, but here in Tuckerman an fair amount is visible so stick to these areas whenever possible. I do think that when you move off old surface into new pockets you may find unstable soft slab. So be cautious when you move off of the old surface. Snow showers are expected on and off through the week so expect loading snow in the ravines. ALSO, WHEN THE WINDS DO BEGIN TO WRAP AROUND TO THE SW, W, NW, OR N AND INCREASE, EXPECT A SIGNFICANT AMOUNT OF LOADING TO OCCUR. This is the primary avalanche factor we are watching right now. So watch the wind speeds and directions closely. AS ALWAYS, THIS ADVISORY IS ONE MORE TOOL TO HELP YOU MAKE YOUR OWN DECISIONS IN AVALANCHE TERRAIN. It should be used along with your own snow stability assessments, knowledge of safe travel techniques, skill in mountain weather's effect on the snowpack, and avalanche rescue. THE WINTER LION HEAD ROUTE IS OPEN. The route leaves from the Huntington Fire Road and has orange signs starting on the Tuckerman Ravine trail at roughly the 1.8 mile mark. It is a steep and challenging route. Crampons, and ice axe, and the ability to use them with skill are required for safe travel. The John Sherburne ski trail is getting better with this past storm. However, waterbars, rocks, and are hidden just under the new snow. PLEASE REMEMBER: o Any new precipitation may increase the avalanche danger, this includes wind transported snow. o Obtain latest weather forecast before starting out. o For more information, contact the U.S. Forest Service Snow Rangers: AMC at Pinkham Notch Visitor Center or Hermit Lake Shelters. o THIS AVALANCHE BULLETIN WILL EXPIRE AT MIDNIGHT.
