The system underwent explosive cyclogenesis dropping from 982 mbar at 15h UTC on Dec 6 to 965 mbar at 6h UTC on Dec 7 – a drop of 17 mbar in 15h, true bombogenesis, as reported by Centre Meteo UQAM. The center of the cyclone moved just north of Scotland during the late morning and early afternoon hours of December 7, with central pressure hovering around 963-965 mbar. Peak wind gusts of 187 km/h were reported at Cairngorm (1245 m elevation), with most locations in northern and central Scotland reporting gusts in 110-140 km/h range. Gusts up to 110-140 km/h were reported along the southwestern coast of Norway and well over 160 km/h offshore.
