Yeah, we had done this before, but typically we had a "short range" or "threat" thread when there was something that was reasonably assessed to be quite likely to occur. I'd defer a "threat" thread until we actually really have something that shows up consistently. I don't exactly see that right now. Just my two copper coin's worth (not much!).
Though, as @WinterWxLuvr mentioned above, I also recall that we did have a general "short range discussion" thread too, maybe the threat stuff was separate discussions once a real storm took shape.
(ETA: Maybe it's been so long since we had a discrete real threat that I have forgotten, LOL!!!)
