Firefighters are continuing to tackle a 'significant' fire involving grass and woodland on the Roaches near Leek.
At it's height, 80 firefighters were at the incident on land off Roach Road at Upper Hulme.
They were first called out to the incident around 1:30pm yesterday, and have been battling the blaze through the night.
Bosses say they expect to be there into next week.
A helicopter has now been drafted in to help get water onto the fire, in the areas crews can't reach
Dams have also been set up in use to supply water to the area.
The surrounding roads remain closed - Hulme Road and the bordering country lanes which loop around the Roaches ridge.
After a resident was treated for smoke inhalation yesterday, and members of the public were seen trying to walk through - emergency services are reminding people to avoid the area.
Deputy Chief Fire Officer Rob Barber said: “This incident is likely to continue for some time, the terrain and wind conditions are causing us difficulty in accessing the fire safely. We are tackling the fire from both sides and will be looking to use a helicopter to put water on the fire from above - this is being sourced by colleagues from Staffordshire Wildlife Trust.
“We’re also working closely with colleagues from Seven Trent, the Peak District National Park and colleagues from Derbyshire Fire Service who are helping supply water.
“Overnight we evacuated two rural homes and we continue our efforts to protect these properties. Any residents that need to leave will be informed directly.
“Smoke is still travelling some distance so please keep doors and windows shut if you’re in an area affected by it.
“We’d like to thank the public for offers of support and local businesses for providing refreshments.”
We are now taking donations for our firefighters of non perishable food and drinks. Donations can be made to Leek Community Fire Station between 9am-5pm. Any donations not used will go to other good causes. We are extremely grateful for your support during this large fire pic.twitter.com/X92si540NB— Staffordshire Fire (@StaffsFire) August 10, 2018
