This video, below, of extreme fire behavior was posted by Shane Fitzsimmons, the Commissioner of the New South Wales Rural Fire Service in Australia. It shows a fire whirl, sometimes incorrectly called a fire tornado. Fire tornados exist, but they are much, much larger and can last for up to an hour or so and average 100 to 1,000 feet in diameter with rotational velocities up to 90 MPH.
Video taken yesterday by Group Captain Andrew Macdonald, with the Macarthur Strike Team, whilst patroling a back burn on the Wallangarra Fire. Shows just how challengeing some of the fireline conditions are for crews working in the very dry, hot and windy conditions. #NSWRFSpic.twitter.com/IZA4crCg9j
It is burning in both Queensland and New South Wales, Australia
A very large bushfire has burned at least 43,800ha (108,232 acres) in Queensland and New South Wales in Australia. Smoke from the fire is affecting Wallangarra, Tenterfield, Stanthorpe, and Jennings.
At 8:55 a.m. local time on February 19 the New South Wales Rural Fire Service reported that the fire continues to burn west of the Bruxner Highway in the Girraween, Bald Rock, Boonoo areas.
Most activity overnight was on the southwest side of the fire near Sunnyside, on the northwestern side of the fire in Girraween National Park (Queensland), north of Wallangarra, and on the southeast side near the Bruxner Highway.
During the night crews conducted backburning operations which increased the fire activity and the production of smoke. This smoke is likely to settle around the areas of Tenterfield, Jennings, Wallangarra and Stanthorpe (QLD), but will begin to clear late Tuesday morning.
Winds in Australia that have changed directions several times in recent days have been pushing a large bushfire in multiple directions. The Tingha Fire that started Sunday in New South Wales has burned around the community of Tingha closing roads in and out of the community. The blaze is between Inverell and Guyra.
NSW Rural Fire Service Commissioner Shane Fitzsimmons said firefighters indicate “numerous properties” including homes, sheds and other outbuildings were damaged or destroyed Wednesday afternoon.
ABC Australia reported that a 40-year old woman was charged with allowing her trash fire to escape, which ignited what has developed into a 30,600-acre (12,400 ha) wildfire.
The Rural Fire Service said winds on Thursday are expected to push the fire closer to Gilgai. Other areas threatened include Old Mill, Stannifer, Guyra Road east of Tingha, and the Howell Road area. But weather conditions on Thursday should be more favorable for firefighters.
On the map below, Tingha is in the center — where two major roads intersect.
Firefighters are facing tough conditions at the fire at Tingha. The fire has impacted on a number of rural properties and is burning on the northern and southern side of the town. #nswrfs#nswfirespic.twitter.com/jqnMqzaj6Y
On December 12 firefighters from New South Wales Rural Fire Service and Victoria Country Fire Authority responded to a fire in a hay shed on Howlong-Balldale Road northwest of Howlong, NSW.
In a tweet the NSW RFS warned about spontaneous combustion:
With warmer weather the risk of hay stack fires increases. This fire attended by crews between Howlong & Corowa. With hot weather on the way landholders should check the temperature in stored hay & if possible ensure that farm machinery is kept in a separate shed.
“Oddly enough, wet hay is more likely to lead to a spontaneous combustion fire than dry hay. If hay is put into a barn or stack when it has more than about 22 percent moisture, not only does the hay loose forage quality, but it has an increased risk of spontaneous combustion.
“High moisture hay stacks can have chemical reactions that build heat. Hay insulates, so the larger the haystack, the less cooling there is to offset the heat.
“When the internal temperature of hay rises above 130 degrees Fahrenheit (55 degrees C), a chemical reaction begins to produce flammable gas that can ignite if the temperature goes high enough.
“Hay fires generally occur within six weeks of baling. Heating occurs in all hay above 15 percent moisture, but generally it peaks at 125 to130 degrees F, within three to seven days, with minimal risk of combustion or forage quality losses. Temperature within a stack then declines to safe levels in the next 15 to 60 days, depending on bale and stack density, ambient temperature and humidity, and rainfall absorbed by the hay.
“To avoid hay fires, small, rectangular bales should not exceed 18 to 22 percent moisture, and large round or rectangular bales should not exceed 16 to 18 percent moisture for safe storage.
“In addition, you should check your hay regularly. If you detect a slight caramel odor or a distinct musty smell, chances are your hay is heating. At this point, checking the moisture is too late, and you’ll need to keep monitoring the hay’s temperature.”
On November 22 Air Tanker 137 dropped on a bushfire in New South Wales
(This article was first published on Fire Aviation)
On November 22 Air Tanker 137 made the first drop by a Boeing 737 on an active fire. It occurred in the Hunter region of New South Wales, Australia.
Coulson completed the conversion of the 737 a few months ago and it is now working on a contract with the New South Wales Rural Fire Service during their summer. Nicknamed “Gaia”, it arrived at Richmond RAAF Base near Sydney November 11 after a multi-day trip across the equator. It will be primarily based at the RAAF Base along with three other large air tankers from North America — a C-130Q (T-134), and two RJ85s (T-165 and T-166). Two other large air tankers will be based in Victoria at Avalon Airport in Melbourne, a C-130Q (T-131), and an RJ85 (T-163).
The 737 Large Air Tanker ‘Gaia’ has been in action in the Hunter this afternoon – the first time this kind of plane has been used to fight a fire anywhere in the world. It’s provided valuable support to firefighters on the ground. #NSWRFS#nswfires#avgeekpic.twitter.com/qHnbcddFpe
Going by the coordinates on the images, the fire T-137 dropped on was very close to the Kurri Kurri Hospital southwest of Heddon Greta. The NSW RFS reported at 8:14 p.m. local time on November 22 that firefighters assisted by aircraft had slowed the spread of the fire. They estimated it had burned 61 hectares (151 acres).
