Avalanche Details

With poor visibility and obscured skies yesterday, the start zones for these three natural avalanches were not seen and there are still many unknowns.

There had been 3-4" of new snow during the day (.2-.3" of SWE), moderate south winds (5-10mph gusting in the teens) at the MP 45 ridgetop weather station and temperature in the low 20'sF.
