Noticed a pattern with storm damage on silver maples in my neighbor's yard

I was walking through my neighbor's property last Saturday after that big windstorm we had, and I saw something kind of interesting. Every one of their silver maples had cracks or splits right at the same crotch angle, around 45 degrees or so. Three of the four trees had major limb failures, and all of them were at that narrow V-shaped union where two big branches meet. I think the weak attachment there just can't handle the wind load like a wider U-shaped crotch can. Has anyone else seen this kind of consistent failure pattern in a specific species before?

This hits close to home. I had a silver maple in my own yard that dropped a limb on my truck a few years back, right at one of those tight V-junctions. Still a sore subject, honestly. My mechanic joked that the tree was just trying to help me justify a new truck, but my wallet didn't find it funny. You're spot on about the narrow angles being a problem. In my experience, silver maples grow so fast that the wood doesn't have time to form a strong union. That consistent failure pattern you saw is pretty textbook for the species. Take it with a grain of salt, but I've seen that same exact thing in about half the silver maples I've come across after a big storm.

Read that silver maples are notorious for weak branch unions (something about fast growth and narrow angles).
