A watch and act has been issued and a number of road closures are in place as more than 20 firefighters and aerial support battle a fire in Boyatup, Howick, Beaumont and Cape Arid.
The blaze, caused by lightning, began on Sunday morning, February 24, and has since burnt 17,500 hectares east of Esperance.
Authorities have issued a watch and act for those in or near Tagon Road, Shao Lu Road, Orleans Road, Henkes Road, Muntz Road, Grewar Road, Merivale Road, Fisheries Road and Balladonia Road and surrounding areas - with a possible threat to lives and homes.
Those in the area are being urged to leave immediately or prepare to actively defend, with those not at home urged not to return.
Both Condingup Primary School and Cape Arid National Park's Thomas River Campsite have been closed, with the Department of Fire and Emergency Services warning that the hot weather expected in the coming days could see fire conditions worsen.
Local farmer units are also assisting at the fire, which is out of control and unpredictable and moving in a south westerly direction.
Motorists are being asked to avoid the area, reduce speed, and be aware of fire and emergency services personnel working on site, with road closures in place on Fisheries Road, East of Henkes Road, and Merivale Road, East of Alexander Road.
The Shire of Esperance have advised that a number of other road closures will be in place as a result of several fires burning throughout the Esperance region.
Parmango Road and Balladonia Track have also been closed and will remain closed until Friday morning, March 1.
The two roads have been closed more than half a dozen times since early January, after a fire was caused by a lightning strike.
According to the shire, there is expected to be a significant amount of activity in and around Esperance for the rest of the week and over the long weekend as result of the fires burning in the shire.
A Harvest, Machinery and Vehicle Movement ban will be imposed from Wednesday, February 27 and Thursday, February 28.
Additional fire fighters and support crew will be heading to Esperance to assist in fighting these fires, with an increase in the demand on accommodation and meals for fire personnel, on-the-ground and support crews.
