On 17 February the Met Office issued a rare Red Alert warning (danger to life) for western coasts of South West England and Wales, later a similar warning was issues for part of South East England, including London. In Ireland Met Éireann also issued Red wind warning for southwestern areas.
Meteosat-11 water vapour image loop (Figure 1) follows the explosive cyclogenesis process of Storm Eunice. Along the jet axis, already in the early hours of 17 February, the first signs of tropopause folding and a cloud head formation starts to show just north of Azores. The initial low pressure centre starts to deepen, moving in a west-north-west direction along the elongated jet. This cyclone deepening is tightly related to further tropopause folding, manifested as a dry air intrusion at the higher levels of the troposphere (red shades in the water vapour imagery). The drier the upper troposphere, the stronger the cyclogenesis process.

The True Colour RGB comparison (Suomi NPP VIIRS on 18 Feb at 11:55 UTC v Terra MODIS on 30 Jan at 11:15 UTC) shows much more pale blue shades of sea surface during the onset of high winds, due to enhanced reflection from the white caps and sea spray.

In continental Europe, where the storm was named Zeynep, Meteoalarm issued red warnings for part of the Netherlands and Germany (Figure 4).
