Wildfire alerts remain in place across the UK as a third heatwave continues to grip the nation, with experts warning of a dangerous phenomenon called a 'firewave' — an event where multiple wildfires occur in urban areas. The chances of wildfire ignition have 'never been so high,' according to officials, and an 'exceptional' wildfire risk has been declared across parts of the UK.
Red Alert and Major Incidents
A red alert remains in place for southern England, the Midlands, and parts of northern England. Major incidents have been declared in Conwy, north Wales, and in Glossop, Derbyshire. Firefighters are facing 'extreme pressure' as they battle dozens of blazes.
London Mayor Sadiq Khan urged Londoners to create firebreaks to protect their homes after a blaze swept through 30 gardens and damaged properties in Walthamstow. Fire crews were also called to incidents in Hampshire, Durham, West Sussex, East Sussex, Devon, and Somerset.
Wildfire Statistics and Expert Warning
Data from the National Fire Chiefs Council shows that fire and rescue services in England and Wales responded to 342 wildfires between 6 July and Monday. Joe McNorton, a scientist at the European Centre for Medium-Range Weather Forecasts, said: 'Across the UK we are seeing a combination of hot, dry weather and vegetation that has become increasingly combustible after a prolonged period without significant rainfall.'
He added that conditions 'even in the UK, where large wildfires are relatively uncommon... can allow fires to spread quickly through grass, heath and moorland once they start.' McNorton noted that 'wildfire risk has a memory, and it can take weeks or even months of warm, dry conditions to remove moisture from vegetation and create a landscape that is ready to burn.'
Public Safety Advice
Garth Smith, head of resilience at the British Red Cross, said: 'Wildfires spread with devastating speed, destroying homes, habitats and lives. Hot weather and little to no rain have made it easier for grass and wildfires to spread quickly.' He advised those in high-risk areas to 'know your escape routes, follow local alerts and keep your property clear of flammable materials.'
Smith added: 'We know the country is getting hotter, and heatwaves and wildfires will be an increasing reality here in the UK. Taking a few minutes now to learn the risks could save lives later.'
International Context
The warning comes as 13 people died with dozens still missing in one of Spain's deadliest wildfires on record. Several victims were found inside burnt-out vehicles, believed to have died while trying to flee the flames. It is feared that four British nationals are among the dead.
