Officers from Cleveland Fire Brigade have been called up to help with the ongoing wild fires near Manchester.
A total of 10 firefighters and two appliances from the brigade have journeyed to Lancashire to assist colleagues in putting out the fires.
More than 20 fire engines are at the scene after the firefighting operation resumed at dawn today.
Crews remained at Winter Hill near Bolton overnight after a "large-scale attack" was launched against the "rapidly developing, aggressive fire" on Sunday.
Lancashire Fire and Rescue Service (LFRS) said it had increased the number of fire engines at the scene from 17 to 22 as the full-scale operation began again at first light.
A major incident was declared on Saturday after two large-scale moorland fires merged due to increasing wind speed.
Helicopters were brought in as the operation sought to douse smouldering hot spots and soak nearby woodland to avoid fire taking hold.
LFRS has been assisted at the Winter Hill blaze by Greater Manchester Fire and Rescue Service (GMFRS), which itself has been tackling a large-scale wildfire on Saddleworth Moor.
Ian Hayton, chief fire officer at Cleveland Fire Brigade, said: "Wild fires present dangerous circumstances for firefighters, particularly from changes in weather.
"We would like to wish the firefighters who are attending this incident well.
"We will be working with Lancashire Fire and Rescue Service over the next few days to establish any further support by rotating those who have been deployed."
