UPDATE: DRY and gusty northerly winds have prompted the Bureau of Meteorology to issue a fire weather warning for the Darling Downs, Granite Belt, Maranoa and Warrego districts.
Fire crews are already fighting and monitoring a number of fires in the region, including a large blaze on the Diamantina Developmental Rd, about six kilometres west of Charleville.
Water bombers returned to the site early this morning to douse the southern and eastern flanks of the fire.
Crews are also monitoring and fighting grass and scrub fires at Teelba, south east of Surat; Mt Binga, east of Cooyar; Forestvale, north of Mitchell; Mt Bindango, west of Roma and at Mt Colliery, north east of Killarney.
A Bureau of Meteorology spokesman said the winds, which are expected to reach 35kmh, would cause severe fire danger in the region.
The threat was realised close to Toowoomba yesterday when a fire started in more than 12ha of dry pasture on a Wyreema Rd property at Westbrook about 11am.
Toowoomba firefighter Neil Goodman said the blaze broke out when fencing contractors were burning scrub to gain access to a fence line.
"People need to be aware of what they are doing," Mr Goodman said.
Wyreema horticulturalist Ray Diak, whose property adjoined yesterday's fire, said he was wary of the increased risk.
"We usually don't have too much trouble around here because most of it is cultivated," Mr Diak said.
"But with all of the rain earlier in the year there is a lot of fuel (dry grass) around."
The fire comes as authorities battle blazes around the state, including a 450ha bushfire at Silverdale, near Boonah.
Three water-bombing planes flew into south-west Queensland from Archerfield yesterday, and two attacked a large scrub fire burning about 6km west of Charleville on the Diamantina Development Rd.
The other plane was called to help crews fighting a scrub fire at Glenmorgan, near Inglewood.
Queensland Fire and Rescue Service south-western regional manager for rural operations Wayne Waltisbuhl said the entire region was on a heightened alert with forecasts of very high to severe fire danger in coming days.
