The National Weather Service Forecasts-

TODAY...SNOW SHOWERS...DIMINISHING IN THE LATE MORNING. SNOW
ACCUMULATION TO 1 INCH. HIGHS AROUND 35. EAST WIND TO 10 MPH.

TONIGHT...SNOW DEVELOPING IN THE EVENING...MIXING WITH RAIN LATE FROM DOWNTOWN JUNEAU SOUTH. SNOW ACCUMULATION AROUND 2 INCHES. LOWS AROUND 32. SOUTHEAST WIND 5 TO 10 MPH.

THURSDAY...RAIN AND SNOW IN THE MORNING...THEN RAIN...HEAVY AT TIMES IN THE AFTERNOON. SNOW ACCUMULATION TO 1 INCH. HIGHS AROUND 39. SOUTHEAST WIND 5 TO 15 MPH.

Temperatures continue to slightly cool. They have dropped 3c degrees in the last 72 hours. Mostly a slow consistent falling rate.

Winds have been under 20mph for the last 48 hours and just picked up to 18-22mph at the Eaglecrest summit over the last few hours.

Conditions have been fairly dry. We received 2mm of precip in the last 36+ hours which left 1\" of new snow.

With not much additional snow in the forecast today and continued cool temperatures avalanche danger is low.

With winds increasing and our precip volumes starting to rise over the next 2-3 days avalanche danger is on the rise. Today danger should remain low. Same for early tomorrow. By the time we go into Thursday evening precip volumes will rise a great deal which will start to rise avalanche danger more and more at that time.

Tip:

Terrain Trap:

What will happen if it slides? The consequence of an avalanche is one of the most important factors in judging the danger of avalanche terrain. Bad consequences include trees (the ?giant bread slicer?) a large cliff or a terrain trap. A terrain trap is a sharply concave part of the runout such as a gully, an abrupt transition or a crevasse where avalanche debris will pile up deeply. Since shoveling takes such a long time, deep burials have a very low chance of survival. Very few victims live from burials deeper than about 5 feet. Even a small avalanche off the side of a gully can have very deadly consequences.
