Storm Debi marks the earliest point in a storm season the letter D has been reached since the Met Office began naming storms in 2015. Storm seasons run from the start of September until the end of the following August.
Before 2023, the earliest month in which the letter D was reached had been December, which happened in 2015 (Desmond), 2017 (Dylan) and 2018 (Deirdre).
The named storms in this year’s season so far have been Agnes (September), Babet (October), Ciaran (November) and Debi.
