Wildfire Risk - southern, central and eastern areas of England
The Met Office has issued a yellow wildfire alert - the forecast high temperatures over the next couple of days are expected to produce an elevated risk of wildfires, particularly across southern, central and eastern areas of England.
The photo shows the situation tomorrow (Tuesday). The light brown area is an indication of an area of very high Fire Severity Index (FSI). There is more detail about the FSI, and how it is calculated, on the MetOffice website.
