This isn't a live sighting, but there is a very serious wind storm causing high winds and flooding in a good part of western Europe including Great Britain and Ireland, and apparently centered on the Netherlands, Germany, Denmark.
Not knowing what route or flights may have been planned by production at this stage of the Race, it is possible alternate legs or routes may have had to be used since this storm would impact rail, highway and air routes throughout much of Europe.
And there's another storm in the eastern Atlantic that already has winds exceeding gale force up to 60 mph near the Azores and expected to head towards Europe, and which may become a subtropical or tropical storm before then.
There's no certainty about whether either storm system is having an impact on filming, but it is something to be aware of.
