BOISE, Idaho (AP) — Air and ground crews are responding to a wildfire in southwestern Idaho just outside Melba. However, fire officials say the flames are no longer threatening 20 homes. Owyhee County dispatchers had previously warned residents in the area to be ready to evacuate.

A spokesman with the U.S. Bureau of Land Management says flames broke out on private land and quickly spread on Tuesday afternoon. Officials say the fire is about 500 acres and is being fought by four aircraft as well as eight fire engines.

The cause is under investigation. The fire is burning near Givens Hot Springs, a popular recreation spot along the Snake River. Southern Idaho is currently experiencing temperatures in the 90s, which can trigger extreme fire conditions.
