A firestorm that sprung from a devastating 2003 bushfire in Canberra, Australia, has been called the world's first confirmed case of a fire tornado.
The twister packed horizontal winds "in excess of 250 km/h [155 mph]" with vertical speeds "at 150 km/h [90-95 mph]", the Australian ABC News website said.
"Our analysis indicates that the tornado had a rating of at least a two on the enhanced Fujita scale of tornado severity," lead researcher Rick McRae said, quoted by ABC.
A wind speed above 155 mph is marginal between F-2 and F-3 on the Fujita-Pearson tornado intensity scale.
McRae, of the Bushfire Cooperative Research Centre, made the distinction between fire whirls, which are fairly common, and this full-blown tornado, which was apparently anchored to a parent thunderstorm.
The tornado had a basal diameter of "nearly half a kilometer [third of a mile]" as it neared the outskirts of Canberra.
Pine plantations were felled, houses were unroofed and cars were blown of the road, according to McRae.
The fire claimed the lives of 4 people and destroyed 491 houses.

Tropical Cyclone Mahasen has necessarily had some say in the onset timing of the Monsoon.
Warmth will wax June-like in some capitals. Many others will experience the feel of mid summer for at least one day.
The Huntsville Mayor, Claude Doughty, said that it would take months and millions of dollars to repair road damage.
Localized severe wind gusts near 60 mph (about 95 km/h) will whip Ireland, Wales, northern England and southern Scotland.
Among the highest observed winds as of Tuesday were gusts of 60 mph at Lechars and 56 mph at Dundee, both in eastern Scotland. In Edinburgh, gusts hit 53 mph.
Much of England, France, the Low Countries and even Germany warmed 5 to as many as 10 degrees C (9-18 degrees F) above normal Sunday. Put another way, daytime warmth was more fitting of early to midsummer than mid-April over a wide area.
