|---|---|
| Danger: | 1 |
| Primary Trend: | 3 |
| Primary Probability: | 3 |
| Primary Likelihood: | 2 |
| Primary Size: | 1 |
| Primary Description: | We have seen mostly light winds but they can easily move this new snow in the starting zones. Be aware of windloading in areas near summit and ridgeline. Danger levels will increase over the next 24 hours as new snow continues to fall during these light winds. Odds of these occurring naturally is highly unlikely. Huan triggers are more possible but not highly likely or widespread today. |
| Secondary Trend: | 3 |
| Secondary Probability: | 4 |
| Secondary Likelihood: | 1 |
| Secondary Size: | 2 |
| Secondary Description: | Watch to see how this new snow load effects the previous weak layers in place. Most of the old storm snow is quite stable... yet we were seeing multiple weak layers that may become recactive as more snow is loaded on to the mousetrap... Once again odds of these occuring naturally is highly unlikely at this time and human triggers although possible are also not highly likely. |
| Discussion: | The National Weather Service Forecasts- Today- Rain and snow showers. Snow accumulation 1 to 2 inches. Snow level increasing to 1000 feet in the afternoon. Highs 33 to 38. Southeast wind 10 mph. Tonight- Rain and snow showers. Snow accumulation 1 to 2 inches. Snow level 600 feet. Lows 29 to 35. Southeast wind 10 mph. Wednesday- Rain showers and snow showers. Snow accumulation to 5 inches. Highs around 35. South wind 10 mph. After last weeks big storm with a few days of settling and consolidation the snowpack was quite stable in most places. We have received about 10.5cm(4+\")of new snow over the last 48 hours. Winds have been mostly calm with periods from 5-15mph. This has produced light windloading I am sure in the lee starting zones. Temperatures have remained fairly constant during this event. Todays forecast calls for light snow with as much as 4\" in the next 24 hours. This is a moderate loading rate and although danger levels will increase some it should not be a huge change in the next 24 hours. We will want to evaluate the bond at the old snow new snow interface from Sunday as it came to rest on a surface hoar that may be quite weak in places. Be avalanche aware... but get out there and enjoy another great day of powder at Eaglecrest. |
