Five named storms so far this seasonpublished at 08:29 Greenwich Mean Time 24 January
Storm Éowyn is the fifth named storm of the 2024/2025 season, which runs from 1 September until late August each year.
The red weather warning in place for the whole of Northern Ireland and Scotland's central belt is not to be taken lightly.
There's only been one other red warning issued this season, which was for Storm Darragh in December. Two people died during that storm.
Before that, the last red warning was issued in January 2024 for wind in Scotland - these types of alerts are not a common occurrence.
It's the most severe type issued by the Met Office, and means there is a threat to life.
Storm Bert, which had a yellow warning in November, led to the deaths of 5 people and caused extensive flooding.
Storm Ashley carried amber warnings and Conall had none, as it was named by the Met Office's partner - the Dutch forecaster KNMI.
