Shap, just outside the Lake District, is the part of the UK that is typically worst affected by heavy rainfall when named storms hit.
It receives an average of just under 6mm of rain on a typical day – already one of the wettest parts of the country – but that almost quadruples to 23mm when named storms hit Britain.
Treknow, near Port Isaac in Cornwall, has been one of the relatively least affected parts of the country.
Even so, rainfall almost doubles there during named storms.
The daily norm there is 3mm, but 5.5mm falls on average while storms are affecting the UK.
Northern Ireland’s weather stations receive more than three times as much rainfall as normal when named storms hit, the biggest increase of any UK nation.
That’s according to analysis of Met Office data by our Data & Forensics team.
The Met Office started naming storms in 2015, and there have been a total of 85 since then, including Austen and Boelo this week.
The busiest storm season so far was 2023/24, when a total of 12 hit.
One of those was Storm Babet, which brought an average of 45mm rain per weather station during the four days it was active, according to our analysis of 263 locations.
Wattisham Airfield in Suffolk recorded almost two months’ worth of typical October rain over those days.
Daily rainfall data for October will be released in early November, when we’ll see how Austen and Boelo compare.
