Avalanche activity is unlikely in the early morning hours. While the snowpack is more stable than the last two days, the general avalanche hazard could increase to Considerable above 7,500 feet if mostly sunny skies prevail through midday. Temperatures are starting out around 5 to 10 degrees warmer than yesterday morning, and most weather stations remained above freezing overnight. The likelihood of triggering wet loose slides and large to very large wet slabs will be on the increase as the day warms. Any extended periods of sunshine could result in natural avalanche activity. Plan on a very early start, monitor the supportability of crusts and the impact of the sun, and be willing to come back another day if conditions warrant. Although the snowpack below 7,500 feet has undergone numerous melt freeze cycles, wet slides may still be possible where the snowpack remains. The final morning avalanche hazard bulletin of the season will be issued tomorrow.

Expect mostly cloudy to overcast skies tonight and through the day on Sunday. Light rain showers up to 10,000 feet will be possible tonight before precipitation intensity increases and snow levels drop to around 8,000 feet by Sunday evening. Overnight lows in the mountains will be in the upper 20s before rising to near freezing during the day. Southwesterly ridgetop winds will back to the east at 5 to 15 miles per hour.The general avalanche hazard is expected to be Moderate on Sunday. Rain into the upper elevations may keep the threat of wet slides alive. On steep, avalanche prone slopes, skiers and riders will have some potential of triggering both wet slabs and wet loose sluffs on a variety of aspects and elevations. Slab depths in the mountains are likely to range from one to three feet. Monitor the intensity of the rain, and be willing to turn around if conditions warrant.
