Wildfires
Authorities are concerned holidaymakers from Perth and elsewhere may find themselves stranded.
The Fire and Emergency Services Authority had urged tourists to leave the Gascoyne region because flooding, linked to the approaching Cyclone Iggy, could cut off the highway to Perth.
But now bushfires have forced the closure of the highway, south of Carnarvon.

Firefighters battle a wind-driven brush fire burning through Pleasant Valley, south of Reno, Nev., Jan. 19, 2012.
About 2,000 people remained under evacuation orders late Thursday as 250 firefighters battled the blaze, said Reno Fire Chief Michael Hernandez, who warned that a full assessment might reveal even more damage.
There was one fatality in the fire area, Hernandez said, but he declined to provide more details, saying an autopsy would be needed to determine the cause of death.
The fire, of unknown origin, broke out shortly after noon in a valley along U.S. Highway 395. Soon, more than 10,000 people were told to flee their homes.

The fires also claimed their first victim: an elderly man who refused warnings to leave his home.
Chile's normally rainy southern regions are suffering from a nationwide heat wave, on top of a drought that makes fires increasingly likely. The country was battling 48 separate fires on Sunday alone, and red alerts were declared for the regions of Magallanes, Bio Bio and Maule.
"We have a situation of extreme vulnerability," said President Sebastian Pinera, who called for toughening sentences for arson.
"It's tough man, it's tough," Reno Fire Chief Michael Hernandez told the Reno Gazette-Journal on Friday. "The winds are not helping us at all."
A spokesman for the firefighters, Larry Helmerick, said Monday the 147-square-mile fire in the Boundary Waters Canoe Area Wilderness is 19 percent contained, an improvement from 11 percent on Sunday.
Helmerick says 598 firefighters are on the ground in the Boundary Waters, where helicopters, tankers and bulldozers are being used to battle the blaze that started with a lightning strike Aug. 18.
Smoke from the blaze traveled nearly 400 miles to Southeast Wisconsin early last week. Two days of smoke and ash prompted air quality alerts across southern Wisconsin.

Canoeists paddle through the narrows between Lake Four and Lake Three, looking south at the fire and the smoke on Sunday, Sept. 11, 2011. "It really grew during the course of the day," said Greg Seitz, communications director for the Friends of the Boundary Waters Wilderness.
Fueled by dry trees and winds gusting to near 40 miles per hour, the Pagami Creek Fire has at least doubled in size, and some estimates say it may have tripled since the weekend.
It is now spreading south outside the Boundary Waters Canoe Area.
"We're expecting higher winds again tomorrow coming out of the northwest," said Becca Manlove, public information officer with the Pagami Creek Fire Information. "We would rather people have a little time to think and gather things and move rather than asking them on very short notice.
In a summer where brush fires have become a near-daily occurrence, firefighting officials said the multiple wildfires that raged across Central Texas on Sunday were the worst the region has seen all year.
Numerous wind-driven fires pushed fire departments to their limits and forced evacuations in Bastrop County, the Steiner Ranch subdivision, Pflugerville, Spicewood and other areas. Scores of residents were left wondering whether they had homes to return to as many of the fires continued to burn Sunday night.
The largest and most destructive fire was in Bastrop County, where a blaze burned 14,000 acres and grew to an estimated 16 miles long by the end of the day, said Mark Stanford, fire chief of the Texas Forest Service.
"It's catastrophic," Stanford said of the Bastrop County fire. "It's a major natural disaster."
One of the most devastating wildfire outbreaks in Texas history left more than 1,000 homes in ruins Tuesday and stretched the state's firefighting ranks to the limit, confronting Gov. Rick Perry with a major disaster at home just as the GOP presidential contest heats up.
More than 180 fires have erupted in the past week across the rain-starved Lone Star State, and nearly 600 of the homes destroyed since then were lost in one catastrophic blaze in and around Bastrop, near Austin. That blaze raged out of control Tuesday for a third day.
Whipped into an inferno by Tropical Storm Lee's winds over the weekend, the blaze burned at least 40 square miles, forced the evacuation of thousands and killed at least two people, bringing the overall death toll from the outbreak to at least four.
"We lost everything," said Willie Clements, whose two-story colonial home in a neighborhood near Bastrop was reduced to a heap of metal roofing and ash. A picket fence was melted. Some goats and turkeys survived, but about 20 chickens and ducks were burned to death in a coop that went up in flames.
Bastrop County Sheriff Terry Pickering said Tuesday he had no details about the deaths. On Sunday, a 20-year-old woman and her 18-month-old daughter were killed Sunday in an East Texas blaze.

Texas Forest Service spokeswoman Victoria Koenig said it is too early to say how much progress was made fighting the wildfire in Bastrop County overnight, but that there were no winds early Tuesday. The fire enveloped at least 25,000 acres Monday.
"It's encouraging we don't have winds right now, not like yesterday," Koenig said early Tuesday morning.

A house burns in an area near Fort Worth, one of over several dozen sites where fires are burning in Texas.
Authorities said the fires, including the one that killed the two people Sunday near the East Texas community of Gladewater, were propelled partly by the high winds caused by Tropical Storm Lee. Neighborhoods across eastern and central parts of the state were reporting widespread damage covering thousands of acres.
"The houses that were in its path on this particular roadway were taken out," Gregg County Sheriff Maxey Cerliano said. "There were many other houses that the fire got right up to the porch."
The 20-year-old woman and her child were found dead near the bathroom of their trailer home just outside Gladewater, about 120 miles east of Dallas and 60 miles west of Shreveport, La. A male occupant of the home sustained minor burns but was able to escape, and he frantically searched for the others, Cerliano said.
