That's a very weird and not very precise way to word this. Of course I would expect auroras to be regularly visible in the far northern parts of the USA and Europe:

Now if you start seeing Auroras in Lisbon or Miami please let me know!

Auroras were seen in Baltimore and Perth (Australia) during the Carrington event in 1859, around Lisbon’s latitude (both north and south)

Lisbon would be worrying but Miami would be catastrophic.

Portugal might be more northern than you think. It's only just south of Toronto.
