TWIN FALLS, Idaho (AP) — Much of southern Idaho is under a red-flag warning with a half-dozen wildfires burning and officials worried that holiday fireworks may spark more. The Bray Lake fire seven miles north of Bliss was reported Wednesday evening.

The Times-News reports officials initially believed it burned 3 square miles. On Thursday, Bureau of Land Management spokesman Joel Olsen says the fire is actually smaller than that, but an exact measurement hasn't been made.

Fire officials expect the Jim Brown fire south of Richfield to be contained Thursday night after burning more than 22 square miles. Meanwhile, the Pointe Fire near Rogerson has burned more than 4 square miles.
