Dense, low, wiry and short-limbed, hawthorn rates intermediate for ice damage and almost never produces a whole-tree failure or a limb on a roof. What glaze actually does to hawthorn is splay the multiple stems outward and bend the leaders over, so post-storm hawthorn work is usually restorative pruning and stem removal rather than a takedown.
Prune in late winter dormancy and stay out of it in a warm wet spring, because like the rest of the rose family it is fire blight susceptible. The trap is purely physical: the thorns are on the interior branches you have to reach through and they will go through ordinary gloves, so interior thinning takes several times longer than the same work on a crabapple, and the base needs an annual pass because the root suckers come back thorny too.
