Walking around in Cardiff today I was noticing how saturated the old snow was that was underlying the 5 inches of new snow, on my return from Cardiff I put a ski cut in the top of Cardiff Bowl and triggered a wet slide that rapidly gouged down 2 to 3 feet and widened out to about 30 feet at the toe. The slide ran fairly fast for a wet slide and left a 10 to 15 foot deep debris pile at the bottom. I'm thinking that the rain from yesterday has loosened the bonds between the melt freeze grains and with no solid refreeze in the last few days things are becoming unstable.
