Collie residents are being urged to have an escape plan ready as smoke clouds fill the air north of the town and bushfires cross in to the Shire of Collie.
The bushfires near Collie have forced roads to be closed and the closure of Wellington National Park.
More than 4000 hectares have been burnt as 70 firefighter battle the blaze.
Collie Volunteer Fire and Rescue spokesperson Julian Martin said people need to be prepared.
"The wind conditions are unpredictable, but the fire is currently heading south towards Collie," he said.
"Make sure you gutters are clear and to have some clothes packed in case of an emergency."
Other items people should have ready are important documents such as passports and birth certificates, medication and photos.
Volunteers firefighters are currently heading to Collie after fighting fires in Waroona at 4am this morning.
The Department of Fire and Emergency Services (DFES) has issued a bushfire advice for people in the northern part of Collie for the area north of Williams Collie Road and Coalfields Road and south of Trees Road.
The advice has been issued due to the intense fire behaviour and fire hop-overs on the southern end of the fire.
Although there is no immediate danger for people in these areas they should stay alert, monitor their surroundings and keep up to date with the fire’s movements.
Residents should also read through their bushfire survival plan and if they do not have a plan decide what to do if the situation worsens.
Approximately 90 firefighters from DFES, the Department of Parks and Wildlife and volunteer bushfire brigades are currently battling the blaze and are being supported from the air.
Firefighters are working on asset protection and strengthening containment lines along the southern and eastern boundaries of the fire. State Emergency Service, Western Power and traffic management staff are also in attendance.
