There is a threat to homes and lives due to an out-of-control and unpredictable bushfire raging just outside the Nannup townsite.
The 4.10pm update on the Emergency WA website said the Watch and Act alert was now in effect for people in the area bounded by Brockman Highway, Gypsum Road, Gerardhi Road, and west of the Ellis Creek State Forest, in Nannup.
The fire started near the intersection of Brockman Highway and Brockman Road in East Nannup and was reported at 1.30pm.
Some roads may now be closed.
People are being told to not fly a drone, model aircraft or multirotor near bushfires.
“Doing so poses a major safety risk to firefighting personnel in the air and on the ground, and forces aircraft to be grounded or redirected, hindering firefighting efforts,” the statement on the Emergency WA website said.
A 2.50pm alert from on the Emergency WA website stated the bushfire was moving fast in a north easterly direction.
People living in the area are asked to leave now if they are not prepared for planned to leave in a bushfire.
People who decided to defend their homes are urged to make their final preparations now.
“If you plan to stay and actively defend, do not rely on mains water pressure as it may be affected,” the statement said.
“You need to have access to an independent water supply, and start patrolling your property to put out spot fires.
“At all times close all doors and windows and turn off evaporative air conditioners, but keep water running through the system if possible.”
People who are not at home are urged not to return as conditions in the area are dangerous.
The roads have not been closed but motorists are asked to avoid the area, reduce speed and drive carefully due to smoke.
Firefighters are on scene, Parks and Wildlife Service firefighters are attending and aerial support has been sent to assist ground crews.
The cause of the fire is not known.
