For years you've been asking us for Lassen Peak weather. Well, now we've got it!

Until this year, collection of weather data in the Lassen Peak area was hampered by the fact that winter-time remoteness (up to fifty feet of snow, steep terrain, and narly weather make the spot accessible only by ski or helicopter) allowed volunteer ski patrols to collect data once a week at best when weather was mild. Conditions permitting, PG&E would also fly in once a month to determine snowpack and water content at the Lake Helen snow course.

This summer, National Park Service compliance and management teams worked with PG&E to find an appropriately low-impact and inconspicuous design and location for a new array of automated snow and weather sensors. The Lake Helen array now collects a variety of weather data that you can view 24 hours a day by going to the California Department of Water Resources' web site.
