Leah reports from big forest fire
Firefighters across the UK are tackling MORE big countryside fires brought on by the hot weather.
Blazes are burning in Berkshire, Yorkshire, Lancashire, the Highlands of Scotland and County Down, Tyrone and Armagh in Northern Ireland.
It's been the hottest April on record and there's only been half the normal amount of rain so it's easy for fires to start and spread.
Prime Minister David Cameron has praised the work of the firefighters.
Police are warning they will arrest anyone suspected of deliberately starting a fire after some teenagers were seen starting fresh fires at Swinley Forest near Crowthorne, Berkshire.
Experts in Northern Ireland say that many of the fires have been started on purpose.
There are about 60 firefighters at a massive moor fire near Mytholmroyd in West Yorkshire and in North Yorkshire a fire is threatening an industrial estate on the outskirts of Thirsk.
Nine crews are at a fire near Belmont, near Bolton in Lancashire, and two engines are at another moor fire near Ormskirk. A Lancashire Fire and Rescue Service spokesman said: "We are hoping it rains, as the land is so dry."
A large area of heather and gorse was on fire on the Balmoral Estate, the Royal Family's home in Scotland.
Fires in the wild can be caused by sunlight shining through bottles or glass and causing a spark or by cigarettes that aren't put out properly.
