BOISE, Idaho (AP) -- A grass and brush fire 30 miles south of Hammett was threatening several ranch homes Sunday and had grown to 156 square miles, according to the National Interagency Fire Center in Boise.
About 200 firefighters working on the Clover Fire hoped to have the blaze contained by Sunday evening, officials said.
The lightning-caused blaze started Friday night and had spread to more than 109 square miles by Saturday, fanned by winds of up to 35 mph.
On Sunday, fire crews reported fire whirls and other extreme fire behavior, according to the Bureau of Land Management.
Two helicopters and 31 engines were brought in to fight the blaze. Bureau of Land Management officials have not yet estimated how much money has been spent to fight the fire.
So far, the fire has burned one shed and some grain fields, officials said.
