20100207 weather data for the 24 hours to 5.30am at 800m
Previous Day Field Observations:
Extreme winds from the NW yesterday (120kph at 2000m and 60kph gusts at valley bottom). Also heavy snowfall - see data below. High avalanche danger in steep backcountry right now as it has been for a few days running. We are staying on lower angle unthreatening terrain in areas of less storm snow.
Please note that this is not an official avalanche bulletin. It isn't even an amateur one. I am only providing some info that we see in the mountains along with my personal and informal opinion. Often the data is incomplete and my opinion wrong. You should only use it as a small input to your own decision making.
