On 9 February 2026 the Met Office launched what it described as its most significant scientific upgrade in more than three years, an improvement enabled by the Met Office’s new supercomputing capability. The Met Office says the upgrade will deliver clearer, more accurate forecasts and give emergency responders earlier insight into flood, wind and travel risks so they can better protect communities during extreme weather.
The update is expected to help local teams — including Sefton Council (the Lead Local Flood Authority) and the Environment Agency — by delivering much more granular, sub‑kilometre forecasting that can be used to produce more localised, street‑level guidance than older regional products. Local authorities and resilience partners say that more localised forecasts will improve their ability to target resources and warnings to specific neighbourhoods.
Bootle is a coastal town with known surface‑water and drainage vulnerabilities. Sefton Council’s Section 19 investigation into the intense rainfall on 30 September 2024 records that 37 properties were flooded internally; the investigation and subsequent local planning documents identify a need for improved mitigation and response. Local officers have said hyper‑local forecasting would help them prioritise actions such as drain clearing and deploying temporary barriers earlier in a storm event.
Residents can use the extra warning time to plan travel or seek support and advice from local flood‑preparedness resources such as The Flood Hub. The Met Office has said this is the first major scientific upgrade delivered on its new supercomputing platform and that the enhanced modelling and computing power will improve weather predictions across the UK compared with previous capabilities.
