Residents in Cyclone Alfred’s danger zone have been warned they only have hours to escape, while there are fears an entire coastal city in northern NSW will be inundated with water.

As millions wait for Cyclone Alfred to make landfall, not everyone is looking to the Bureau of Meteorology for their information.

Tropical Cyclone Alfred is forecast to make landfall somewhere between the Gold Coast and Sunshine Coast on Thursday.

Temperatures could soar above 40 degrees celsius across vast stretches of WA this weekend as a heatwave grips and expands over the continent.

Parts of Victoria and South Australia have been warned about extreme fire conditions on Saturday, with temperatures in some regions to reach the early 40s.
