BEND, Ore. -

Firefighters face a couple of days of gusty weather as they try to finish drawing lines around the first big wildfire of the season in Oregon.

Authorities gave residents of 200 homes northwest of Bend the OK to go home Sunday. The residents of about 50 more homes remained under an evacuation notice.

Spokeswoman Lisa Clark of the Central Oregon fire dispatch center said Monday morning that the weather will make the Two Bulls fire especially challenging until about Thursday. Cooler weather is expected then.

Wind speeds Monday afternoon are expected to be 10-18 mph.

The fire is burning in brush, juniper and Ponderosa pine territory, part federally owned, part private. No injuries or serious damage has been reported. Authorities say the cause is unknown.
