The National Weather Service Forecasts-

TODAY...RAIN...HEAVY AT TIMES. HIGHS AROUND 43. SOUTHEAST WIND 10 TO 20 MPH.

TONIGHT...RAIN...HEAVY AT TIMES. LOWS AROUND 37. SOUTHEAST WIND 15 MPH INCREASING TO 15 TO 25 MPH LATE.

TUESDAY...RAIN. HIGHS AROUND 43. SOUTHEAST WIND 15 TO 25 MPH
DECREASING TO 10 TO 15 MPH IN THE AFTERNOON.

Temperatures remain quite warm in the region. Mt Roberts is holding at 33f while Eaglecrest is 34f at the base. 32f mid mountain and about 30 on top.

We have received quite a bit more precipitation in the last 24 hours than the forecast originally called for. Eaglecrest had well over 1\" of precipitation at 31mm. This left about 17cm of new snow at the mid mountain elevation. I am sure there is quite a bit more than that at upper elevations. The Tram received quite a bit less at 20mm of precipitation leaving us 13cm of wet heavy snow. Once again there could be quite a bit more at higher elevation.

Winds started strong yesterday with Mt Roberts showing 15-25 out of East. They have now fallen to 10-15 which is still considerable accompanied with new snows. Eaglecrest was blowing 20-30 yesterday out of the SE and has since slowed to 15-20 which still transports a great deal of snow.

With considerable to high winds over the last 24 hours, 5-7\" of new snow on the upper mountain and a forecast that calls for nearly 2\" of precipitation in the next 24 hours avalanche danger is HIGH at this time. Natural Avalanches Likely and Human-Triggered Avalanches Very Likely.

You will see a wide array of types of avalanches from Storm Slab to wind slab up high. At mid to lower elevations you will see more wet slab and wet loose avalanches.

Be aware that this next 36 hours heavy rains will place significant stress on the snowpack snowing any weakness that may exist. Look to see both human triggered and natural avalanches.

Use good route finding techniques and be safe out there!

Here is a great video from Doug Chabot of the Gallatin National Forest Avalanche Center on how to perform technical snowpit stability tests.
