The National Weather Service said about a half an inch (1.25 centimetres) of precipitation in the form of rain and snow fell early yesterday southwest of Wichita in Barber County, which accounts for 1,106 of the 1 ,600 square kilometres scorched during the blaze that began Tuesday in Oklahoma before spreading into Kansas.
Forestry officials in both states said yesterday the fires had been 45 per cent contained, including roughly one-third of the blaze in Barber County. But shifting, stiffer winds were expected, potentially reigniting hot spots or extending flames beyond the fire line.
While crediting the Kansas snowfall for quenching dry, vulnerable prairie grass, native cedar trees abundant around Barber County caught much of that precipitation on their branches and left possible hot spots beneath them parched and at risk of rekindling, Kansas Forest Service spokeswoman Shawna Hartman said.
The precipitation also likely offered little fire-suppressing benefit in the area's drainages and sloping canyons, she said.
Six homes have been destroyed and some livestock has been lost, the Kansas Adjutant General's Office said. Three bridges and one railroad trestle have also been damaged or destroyed. No people have been seriously injured.
A Federal Aviation Administration temporary ban on flights involving aircraft not assisting in the firefight, including unmanned drones, remained in effect above the burn zone at least until sunset yesterday.
