What is the Sydney Dome?

The Sydney Dome is a curious weather effect we see when a Nor'easter approaches Cape Breton.

Thank you to Roxanne Pike for capturing-and-posting this classic image of the Sydney Dome during the last Nor'easter, date 09 Feb 2017.

(See the video below for an explanation of the Sydney Dome)

So my question is: With two Nor'easters bearing down on us one-after-another, will the Sydney Dome be able to re-establish itself before the second storm arrives?
