Ah, forgot about your location.
Yeah, tough call. Normally I'd say it just looks like a heavy shedding, but with the storm and all...
If you really like it or they are hard to find in your area, a fragging shouldn't destroy it if it is just a shed. Otherwise if they are easy to find up there I'd just wait and see. Unless it is going into a full crash you should get some heads up if it starts rotting. If the whole specimen just up and died from the shifts, fragging probably won't help.
