9:42 a.m., Friday, November 1, 2002 Winter is back in the mountains! Lets all hope for a good winter with lots of low density snow and nice sunny days in between storms. If you haven't already been reviewing your avalanche skills get going, winter is here! Be prepared and well practiced in snow stability assessment, travel in avalanche terrain, and avalanche rescue. This is an early season GENERAL ADVISORY. Use of the 5 scale avalanche rating system will begin when conditions warrant. Until then new advisories will be issued as needed. Check csac.org frequently as we move into November and certainly check for the latest avalanche advisory before heading into avalanche terrain. We received 20 inches of snow during the month of October which is about 60% above normal, so we're of to a good start. Snow showers are forecasted for the mountains today with W and NW winds. As the day progresses winds should increase from 25 to 45 mph from the W then shift from the NW. Expect winds to continue to increase through the evening as a front brings Artic air down from Canada. The first half of the weekend will be quite cold up high before tempering a bit on Sunday. High winds will continue to load new snow onto the small snowfields in some of the traditional early locations. Some examples of typical early season pockets are, high in Left Gully, the Chute, high on the north or right side of Tuckerman, and up on the E and NE side of the summit cone. These snowfields, as well as, exposed ice are the most likely areas for possible avalanche activity during the next series of weather makers. Ice develops rapidly each fall in both Ravines and often act as an excellent sliding layer for avalanches to occur in small pockets that may appear innocuous. It is definitely still early so I don't want to overplay the current hazard or problems out there. However accidents usually occur when you aren't paying attention and don't expect them. The first avalanche accident involving 3 people occured last year in early November so start keeping your eyes open. Be aware that a small slab or sluff can be very dangerous. This is particularly true in the steep gullies and slopes of Tuckerman and Huntington Ravines for early season ice climbers. As a climber picks their way through a route they will usually cross small pockets of snow. Often this snow has deposited over blue ice, making for a poor bond at the interface. Consider this ahead of time and place protection before crossing suspect slopes. It doesn't take much snow to knock you off your feet and depending how high you are this could be a considerable problem. Be aware of falling ice if we get into thaw periods before the real deep winter freeze. Many folks have been injured and killed by falling ice so pay attention to where you are, and don't linger when under ice. Have a plan in mind about what you will do and where you will go if ice comes down. Station yourself near a large rock to duck behind in the event of ice fall. Be ice smart. We are absolutely in early winter in the high mountains so don't plan on being able to follow summer trails safely. Trails going through Ravines and Gulfs are buried with snow in many areas and require winter gear, i.e. winter clothes, ice axe, crampons, avalanche beacons, shovels, and probes. So, winter is here! Don't wait any longer to refresh your avalanche skills. Pull out your beacon and practice, ONLY YOU CAN SAVE YOUR BUDDY!! Review your safe travel rules, techniques for assessing snow stability, and sign up for an avalanche course. We will have all the avalanche courses offered in the valley this winter on our website, csac.org very soon. Thanks in advance to all the groups that will once again be helping us make it through the season successfully. We couldn't do the job without the many volunteer hours carrying hurt people down the mountain and the financial support helping us upgrade rescue capabilities. We sincerely appreciate all your help. 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 General Avalanche Bulletin will be updated as needed.
