A sequence of VIIRS True Color Red-Green-Blue (RGB) and Infrared Window (11.45 µm) images from Suomi NPP and NOAA-20 as viewed using RealEarth (above) showed “Storm Hannah” as it approached Ireland and the United Kingdom on 26 April 2019. The midlatitude cyclone had peaked in intensity as a Hurricane Force low around that time (surface analyses).

EUMETSAT Meteosat-11 Water Vapor (6.25 µm) images (below) showed winds gusting to 40-65 knots at several sites in southern Ireland and southern England, as the dry slot air stream moved across the region. In Ireland the peak wind gust was 66 knots at Mace Head, with 64 knots at Shannon — wind gusts in southern England included 71 knots at Aberderon, 68 knots at Pembrey Sands and 52 knots at Valley.
