Cikita, from what I can tell, produces these swirls long before any beams begin to appear. However, they only become symmetrical and spiral in nature just before an outburst. Preceding this, thin converging lines appear and either spread out from the areolas or converge into them. It could be an indication of a tightening electrical field.
The following three images show this swirling in the absence of any beams. The last image shows the radiating lines as well as a developing "bubble".
