Crews fighting a moor fire near Dovestone reservoir in Oldham say overnight rain has helped them largely extinguish it.
Firefighters spent the night tackling the fire which first broke out just before 2.30pm on Tuesday afternoon.
At its height the fire covered an area of around 600 square metres of Saddleworth Moor near the reservoir Greater Manchester Fire and Rescue Service (GMFRS) said.
Ten fire engines from local stations attended with assistance also being drafted in from the fire services in Lancashire and West Yorkshire.
People were ordered to leave the area, which was busy with sun-seekers enjoying the warm weather, to allow the fire vehicles access to the fire on land off Holmfirth Road.
The blaze also produced a large amount of smoke with fire service bosses last night saying the "tinder-dry ground" and strong winds posed a risk of it spreading.
Crews also had to battle "very harsh conditions in steep, uneven terrain to fight it" they added.
However in an update this morning, GMFRS said the efforts of crews along with the damp conditions overnight had seen the fire largely extinguished with only a few hot spots remaining.
They said in a statement: "Heavy rain has assisted firefighters tackling a large moorland fire near Dove Stone Reservoir, Oldham.
"Throughout the night, heavy rain has helped to extinguish the fire, which firefighters were originally called to at around 2.20pm on June 2.
"A wildfire officer remains on the scene monitoring the situation, with hot spots located in the moor.
"The rain is forecast to continue this morning and once it stops an assessment will be made on what fire services resources are needed at the scene."
Last night specialist fire investigators were dispatched to try and determine the cause of the fire which has still not been revealed.
However Area Manager Ben Levy said: "I urge everybody to take extra-special care when enjoying our open spaces at this time of year, in conditions that can easily lead to large outbreaks of fire like this."
