It's becoming more stubborn to trigger, but the consequences remain quite high if you find the right slab/weak layer combination. These persistent slab avalanches could break on or near the ground in depth hoar. Obvious signs of instability, like cracking and collapsing, most likely will not be present. Take the time to dig a pit to see if this poor snowpack structure of strong over weak exists before committing to a slope.
Avalanches like this are becoming less likely to trigger, but the consequences still remain quite high if you do trigger a persistent slab avalanche, potentially taking with it most of the season's snowpack.
