Friends of the Colorado Avalanche Information Center
Winter 2000-01 Application
The Colorado Avalanche Information Center needs you!
As a Friend, that is. The Avalanche Center works hard to keep you on top of the snow. Our forecasts
are heard daily by thousands of skiers, snowboarders, climbers, hikers, and snowmobilers. But we need
your support to keep the Avalanche Center alive and well … because we are funded mostly by grants and
donations. The "Friends of the CAIC" is the support group of individuals like you who make our forecasts
of weather and back-country avalanche conditions possible.
What you get:
· The best forecast your money can buy.
· Three issues of The Beacon, our newsletter only for our Friends.
· A cool CAIC window decal.
· Avalanche Wise, the CAIC's 24-page information and safety booklet.
· Forecasts sent to you by e-mail every morning by 7 am (and at 3 pm every afternoon if you choose
the higher level of membership.)
Won't you help by subscribing at one of the two levels of services listed below? And please spread the
word and recruit a friend. Thank you.

DISCUSSION:
A weak disturbance is moving through the strong westerly flow this morning.
That will bring lite snow to the N&C Mtns and possibly an isolated shower to
the W San Juans in the S Mtns. Look for winds in all mountain areas to
increase slightly as the jet stream drops a little farther south tonight and
Tuesday. This would normally induce more snowfall, but the available
moisture decreases at the same time. Look for moderate-strong winds to veer
NW Tuesday & Wednesday ahead of a ridge of high pressure moving into the
Great Basin. That will bring a drying trend with warming temperatures
Tuesday afternoon and Wednesday, but moderate winds will continue. The
forecast details:
WEATHER * SAMPLE REPORT *
N&C Mtns
Monday: Cloudy, lite snow, generally 2-5" but locally heavier at some high
elevation sites. Winds W/5-15, but increasing over peaks & high ridges
15-25, G40s. Highs 18-28.
Monday Night: Mostly cloudy, showers to lite snow, 1-2". Winds W/10-20 G40s.
Lows 12-22.
Tuesday: Partly-mostly cloudy, isolated showers possible. Winds NW/10-20
G40. Highs 14-24.
S Mtns
Monday: Partly to mostly cloudy, 0-T" possible for high elevation W San
Juans. Winds WNW/5-15, few G20s over higher peaks. Highs 22-30.

SNOWPACK - * SAMPLE REPORT *
New snow reports so far this morning are: one-half inch at Breckenridge and
Winter Park, 1" at Vail, and 3" at Copper Mtn. Backcountry travelers in
Rocky Mtn Nat'l Park yesterday spotted a small slide on Mt Lady Washington
at about 11,500' elevation on a NE aspect. Also, two small natural releases
were reported yesterday that ran on the 25th on Bear Mtn near Red Mtn Pass.
No fresh slides have been reported this morning. The snowpack in many areas
now consists of faceted, poorly bonded grains, and shallow wind slabs. This
is a poor, but typical, Colorado snow structure. Backcountry travelers
should use extra caution on slopes 35 degrees or steeper. Human triggered
avalanches are possible and some small natural activity might be seen from
the new snow and strong winds in the forecast. This will likely build fresh
shallow slabs near and above timberline in the N&C Mtns. The backcountry
avalanche danger is currently rated:
N Mtns: Near & above treeline, generally MODERATE, but small pockets of
CONSIDERABLE on N-SE aspects. Below treeline the danger is LOW overall.
C Mtns: Near & above treeline, MODERATE. Below treeline, LOW.
West San Juans: Near & above treeline the danger is MODERATE with some
pockets of HIGH on lee aspects and cross loaded gullies. Look for some fresh
drifting on high elevation southerly aspects from strong northerly winds
yesterday. Below treeline the danger is generally LOW due to lack of a slab.
East San Juans: near Wolf Creek Pass, MODERATE on NW-E aspects. LOW
elsewhere.
