Evacuation centres in Western Australia's Mid West have opened in preparation for Tropical Cyclone Seroja, which is expected to make landfall this evening.
The cyclone, which is currently a category two system, is forecast to bring destructive winds and possible flash flooding to the coast this afternoon.
A yellow alert is in place for people near Carnarvon to Kalbarri, excluding the townsites.
A blue alert has been issued for people south of Cape Cuvier to Carnarvon, including the town of Carnarvon, and Kalbarri to Lancelin, including those towns.
The blue alert extends inland to the shires of Northampton, Chapman Valley, Morawa, Greater Geraldton, Mingenew, Three Springs, and Perenjori, along with the townsites of Mullewa, Coorow and Carnamah.
The Department of Communities has opened evacuation centres in Port Denison, Carnarvon and Denham, with some people in Denham asked to evacuate.
Cyclone Seroja is about 500 kilometres west north-west of Carnarvon and 750 kilometres north-west of Kalbarri.
It may intensify to a category three system, but is forecast to drop to a category two before it crosses the coast.
Gusts of up to 100 kilometres an hour are likely between Minilya Roadhouse and Kalbarri during the afternoon.
Ex-Tropical Cyclone Odette weakened overnight, and is set to weaken further after making contact with Cyclone Seroja.
