UK Wildfires
Most parts of England and Wales are now at very high or exceptional risk of wildfires becoming severe, according to a Met Office fire severity index.
The index evaluates the probable severity of a wildfire in England and Wales should one break out.
Large parts of Yorkshire are rated as ‘very high’, with Sheffield frequently shifting between ‘moderate’ and ‘very high.’
Fire crews have fought a moorland blaze on the Peak District at Tintwistle Moor, near Glossop, for more than a month.
The Observer reports how a BBC analysis of the European Forest Fire Information System suggests the fire has now burned almost 650 hectares (about 1,600 acres) and is one of the biggest wildfires ever seen in England.
In Sheffield, South Yorkshire Fire & Rescue have tackled dozens of sudden (and sometimes deliberate) blazes in July, including Greno Woods, Dyke Vale Road, Wensley Street, the A628 Woodhead Pass, and most devastatingly, a fire on Fox Hill that destroyed two terraced houses and badly damaged three more.
