firefighters hosing down the roof of the Emergency Services Bureau. The morning of Saturday 18 January 2003 was hot, windy and dry. Temperatures as high as and winds exceeding , plus a very low relative humidity, were the main weather features of the day. Two fires continued to burn out of control in the
Namadgi National Park, with the entire park, along with the
Tidbinbilla Nature Reserve, being closed due to the threat. A second fire, in the
Brindabella Ranges, was threatening to break containment lines. By 9 am on the morning of Saturday 18 January, burned leaves appeared on lawns in houses in the
Weston Creek,
Kambah, and
Tuggeranong suburbs bordering the western extremity of Canberra. By 10 am, news helicopters were overflying
Duffy and reporting news of the fires interstate and internationally. Throughout the day, the fires burned closer to the fringes of Canberra's suburbs, and there was no sign of authorities gaining control of the situation. At around 2 pm, police evacuated the township of
Tharwa to the south of Canberra. By mid-afternoon, it had become apparent that the fires posed an immediate threat to the settlements near Canberra, such as Uriarra and Stromlo, as well as to the houses on the city's urban-bushland interface. A state of emergency was declared at 2.45 pm by the ACT's Chief Minister, Jon Stanhope. The fires reached the urban area at 3 pm. The first emergency warning advisories were broadcast shortly after, on radio and television, with the advisories updated throughout the day. These advisories, accompanied by the
Standard Emergency Warning Signal stated that a significant "deterioration" of the fire situation in the ACT had occurred and placed several suburbs on alert to evacuate. As the day continued, these advisories advised the evacuation of several suburbs (also enforced by Police on the ground) and placed most suburbs of Canberra on some level of alert. By now, the fire had reached the fringes of many suburbs, was surrounding Tharwa, and threatened the historic
Lanyon Homestead, which was hosting a wedding and protected by only a single fire truck. By 3.50 pm, some houses were alight in the suburbs of Duffy and
Chapman, with the loss of a home in
Holder soon after. An
ACT Fire Brigade unit, perceiving the fire from a vantage point in Fyshwick, overrode instructions by the radio controller to ignore the signs and remain where they were. The unit headed to Duffy, attempting to alert both controllers and residents to the imminent danger. That unit was caught in a fire front on Warragamba Avenue in Duffy at around 4.10 pm, after having rescued at least two residents. Both the crew and residents were forced to flee the appliance when the fire struck. Due to fire damage to infrastructure and extreme winds bringing down powerlines across the area, large parts of the city lost power. Fires also started in
Giralang because of powerline problems. Evacuation centres were set up at four schools –
Canberra College,
UC Senior Secondary College Lake Ginninderra (then Lake Ginninderra College),
Erindale College, and
Narrabundah College. A dark cloud hung over the city, and, although it was not in danger,
Parliament House was closed. By 5 pm, houses were reported destroyed in Duffy, Chapman, Kambah, Holder, and
Rivett, as well as in the small forestry settlement of
Uriarra. It was later found that the first casualty of the fires, an elderly woman named Dorothy McGrath, had died at the nearby Stromlo Forestry Settlement just north of Duffy. Escape for residents of the settlement was hampered by poor warning and by the settlement's location, surrounded by the pine forest. Fires in the Michelago area forced the closure of the
Monaro Highway into Canberra. Fires spread through the Kambah Pool area and into the suburb of Kambah, causing damage to many homes and one of the ACT's primary Urban and Rural fire stations. Fire spread through parkland, crossing the
Tuggeranong Parkway and Sulwood Drive engulfing
Mount Taylor. Within an hour, houses were also burning in
Torrens, on the slopes of Mount Taylor, and in
Weston. By this point, the fire had inflicted severe damage to the city's infrastructure. Power supplies were cut to several suburbs. These outages affected both the Emergency Services Bureau's own headquarters in Curtin and the Canberra Hospital (running on back-up generators), which was under intense pressure from people suffering burns and smoke inhalation. In Curtin, the ESA headquarters was in danger from the fires. With back-up power available only to the Communications Centre, many personnel were forced to work on tables outside as Army Reserve personnel hosed down the building. It was later noted that the ESB could have moved its operations away from danger to other emergency service locations such as the
AFP Winchester Centre or Tuggeranong Police Station. He stated that if the fire had caused a breach in the chlorine tanks, it would have created "a poisonous cloud that would blow toward Canberra necessitating mass evacuations". It was calculated to have horizontal winds of and vertical air speed of , spawned by its own wind rotation from a
pyrocumulonimbus cloud and causing the
flashover of in 0.04 seconds. It was also the first known fire tornado to have EF3 wind speeds on the
Enhanced Fujita scale and the only known one until the 2018
Carr Fire in California. ==Aftermath==
