Where the Canberra bush fires are today, weather forecast and latest travel advice

A state of emergency has been declared in the Australian Capital Territory (ACT), as massive bush fires rage south of Canberra.

Officials said the flames pose the worst fire threat to the territory in nearly two decades, and the main blaze is burning across an area of more than 18,500 hectares.

"The ACT is now facing the worst bush fire threat since the devastating fires of 2003," Chief Minister Andrew Barr told reporters on Friday.

"There's now no higher priority for the ACT government at this time than the bush fire threat."

Residents in the suburbs of Canberra, Australia's capital city, have been told to "remain alert" as orders of evacuation could come at any moment.

Roads were blocked to the village of Tharwa on Friday because the fire posed too much danger for residents to evacuate or return to their homes.

Australia remains in the clutches of one of its worst bush fire seasons on record.

Blazes have been sweeping through the country since September, killing 29 people, destroying 2,500 homes, and razing forests and farmlands to the ground. Land mass equivalent to Bulgaria has been devastated.

New South Wales, Victoria, and South Australia have seen the most disastrous effects of the fires, though other areas of the country have also been impacted.

Where are the fires?

The above map shows the extent of the fires burning near Canberra, with data taken from Australian government website MyFireWatch, which uses satellite data to map heat sources.

Note that the data incorporates "any heat source that is hotter than its surroundings."

"This may include gas flares, refinery furnaces or highly reflective large industrial roofs", according to the website.

That means that the symbols are not guaranteed to indicate actual fires. The hotspot symbols also do not represent the actual size of fires or the danger posed by them.

The fire is burning at emergency level - the highest on a three-tier scale of danger - and embers have created dangerous spot fires nearby, agency officials said.

What's the official travel advice?

"Australia continues to battle serious bush fires across multiple regions," say the Foreign Office in their official travel advice.

"Authorities in some regions have declared a State of Emergency and ordered road closures and evacuations.

"Poor air quality can occur some distance from the sites of the fires and provoke respiratory conditions.

"If you’re in or near an affected area or planning any travel, stay safe, monitor TV news, radio and social media channels for updates, and follow the instructions and advice of local authorities."

Unfortunately, the weather forecast for the area suggests that conditions maybe perfect for the further spread of the fires.

A hot, sticky and stormy weekend is in store, with small chance of any significant rainfall.
