Firies On High Alert As East Coast Braces For Catastrophic Conditions

Water-bombing aircrafts are on standby as south-east Queensland and northern NSW brace for hot and windy weather.

High temperatures, strong winds and low humidity will create an extremely challenging day for firefighters.

The Bureau of Meteorology warns severe to extreme fire conditions could affect central and south-east Queensland, while catastrophic conditions are also possible for parts of the southern interior.

Firefighters will be keeping their eye on strong and gusty northwesterly winds as they bring hot, dry conditions this morning. The strong winds will then swing southwesterly in the late afternoon.

More than a dozen bushfires are already burning across the sunshine state, with residents at Sarabah, south of Canungra on the scenic rim warned to prepare to leave.

A home in far north Queensland has been destroyed by a fast-moving blaze. The fire broke out in Biboohra, north of Mareeba during the hottest part of Thursday -- thankfully no one was injured.

With winds mixed with hot temperatures peaking in the mid-30s, there are fears these could be the worst fire conditions for September in the past six years.

"We need people to pay attention, be aware of what's going on around them and keep up to date," Superintendent James Haig from the Queensland Fire and Emergency service told 10 daily.

"Any fire starting today could be really challenging and could move really quickly".

Firies across the border are also expecting a busy day huge with parts of NSW placed under a total fire ban, including Sydney, as the state experiences its warmest start to the season this decade.

Sydney is forecast to reach 28 degrees on Friday, Newcastle will reach 30 with light winds becoming north to northwesterly 35-50  km/h in the morning before tending west to northwesterly in the late afternoon.

The good news is a cool change is expected to move through the nation's south-east tonight, bringing showers to parts of NSW.

It's a whole different kettle of fish for Melbourne, which is being hit by a cold front.

The city is forecast to reach just 14 degrees today with the chance of a thunderstorm and hail late Friday morning, while almost the entire state of Victoria is bracing for damaging winds.

The wind, rain and chilly temperatures are forecast to stick around until next week.
