GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images (above) showed the circulations associated with a pair of Hurricane Force low (surface analyses) during the 13-15 February 2020 period. At the limb of the GOES-16 Full Disk view, plots of hourly surface wind revealed gusts in the 70-80 knots range at stations in Iceland — including Keflavik International Airport near Reykjavik and Akurnes along the southeast coast. One site north of Reykjavik recorded a wind gust of 138 knots.

Sequences of VIIRS Infrared Window (11.45 µm) and True Color RGB images from NOAA-20 and Suomi NPP during those same days as viewed using RealEarth are shown below.

EUMETSAT Meteosat-11 Water Vapor (6.25 µm) images during the 14-16 February period are shown below. Named “Storm Dennis” by the UK Met Office, the system brought high winds to much of Europe.
