Conditions may evolve quickly at this time of year.
Be wary of loose wet avalanches on steep features, especially if solar radiation is strong.
Surface snow may produce loose wet avalanches in steep terrain, particularly if the solar radiation is strong. Surface crust formation, where it occurs, will neutralize this problem.
No new avalanche was reported, but visibility restricted field observations. Large wet avalanches (up to size 2.5) were naturally triggered during the past storm cycle over the weekend and evidences are still visible around Mt Washington.
30 cm of moist snow is overlying 20 cm of rain-soaked snowpack burying a strong melt-freeze crust. In the alpine, up to 50 cm of moist snow may be found. A sandwich of surface hoar and faceted snow from late January crust is now down 60 to 100 cm. At lower elevations, rain has soaked the snowpack. The lower snowpack is well-settled.
