I think that ever since that massacare that was Kate's fault, Deucalion could've been more attentive to Beacon Hills, and this could've also lead other supernaturals to this area. I mean in Season 3A, Deaton said that Beacon Hills would attract the supernatural once again, or something along those lines, which could imply that maybe other creatures have been keeping a distant watch.

As for Cora knowing, she could have been searching for something where ever she was. I don't think it would be hard to figure out that their is a new alpha, as for werewolve news, I don't know if it does travel fast, but considering there seems to be a limited amount of werewolves, it should!

But considering the Alphas did know a lot they might have been around snooping in secret. It wouldn't surprise me if they do a few flashback moments and add in scenes that weren't there in Season 2 for Season 3B. That also would add more interesting turns into the plot.

In the end, both Deaton and Morell along with Peter at the end mention that something bigger is coming for them. Which was a foreshadowing to the Alpha pack so they could've easily known they were already in town. Besides Peter mentions at the end. "They're not coming, they're already here. . ."
