Snowpack getting warm = wet, heavy, weak, slippery, suddenly obeying gravity.
Impact.
Not that gently getting buried by tons and tons of unbreathable suspensions of powdered snow is better. Some rescuees mention they could not tell up from down when buried.
I also expect to see more rescues (sometimes) of people, pets, and livestock crunching through the thinning ice.
