Fire Severity Index - Relocated

The Fire Severity Index (FSI) webpage is in the process of being relocated from the Met Office website to the Open Access website, hosted by Natural England.

A new visualisation for both England and Wales is scheduled to be displayed by the end of April 2025.

During this transition period, the Met Office will continue to provide Natural England with FSI data via a daily feed. This will allow any fire prevention restrictions under the CROW Act 2000, to be activated when conditions are classed as ‘exceptional’. The Met Office will continue to use the FSI data to prepare the daily hazard assessment for the responder community.
