Avalanche Advisory for Tuckerman and Huntington Ravines
Posted: 11:39 a.m., Friday, November 19, 2004

This is an early season GENERAL ADVISORY. Use of the 5 scale danger rating system will begin when conditions warrant. Until then new advisories will be issued as needed. Realize that avalanches may occur even though we are only issuing a "General Advisory" due to isolated instabilites.

The storm that hit the mountain two weeks ago created some good sized snowfields that will serve as the bed surface for potential avalanche activity in the future. The largest of these exist in Left Gully and above the Headwall from the Lip to the Chute. Very small steep pockets exist along the Tuckerman Ravine trail particularly near the Lip. As more snow becomes deposited in these areas in the future be cautious when approaching these locations. Remember that even a few centimeters can elevate the avalanche danger if moderate to strong winds are involved.

A classic "wintry mix" is expected to begin Saturday night through Monday. This is an optimistic way of saying it's going to be an ugly combination of rain, sleet, and some snow. It's kind of like calling rain "liquid sunshine". Rain is expected to return Wednesday afternoon, but a cooler air mass will drop temperatures into Thanksgiving providing for a chance of snow.

If you are thinking about heading into the Ravines to go ice climbing realize that the ice has been a little slow to develop. Most routes are not quite in shape and provide scrappy mixed climbing. Consistent cold temperatures have not yet set in for around the clock freezing so expect poorly attached ice in many locations. Climbers out during the early season have confirmed these conditions. The few routes that have been done this season are reported as "thin detached ice with little or no protection." A heavy concentration on rock gear would be smart. Make sure you know what you're in for before attempting your season's inaugural pitch! Early season mistakes often have dramatic consequences, as rock and ledge aren't quite as soft as the powder cushion later in the season. We have heard of some interesting stories through the grapevine already. Be smart, climb safe.

We are in early winter in the high mountains. Don't plan on being able to follow summer trails safely. Trails going through Ravines and Gulfs are collecting snow quickly and will require appropriate winter skills and equipment to negotiate them safely. Also, be aware of falling ice if we get into thaw periods before the real deep winter freeze.

Don't wait any longer to refresh your avalanche skills, including rescue techniques. Pull out your beacon, install new batteries, and practice, Practice!, 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 have all the avalanche courses offered in and around the valley this winter on our website, tuckerman.org.

Please Remember:
•   Any new precipitation may increase the avalanche danger, this includes wind transported snow.
 
•   Obtain the latest weather forecast and review archived avalanche advisories at www.tuckerman.org for snowpack history before heading into the mountains.
 
•   For more information, contact the U.S. Forest Service Snow Rangers or the AMC at the Pinkham Notch Visitor Center or Hermit Lake Shelters.
 
•   This Advisory will be updated as needed.
