Bastrop officials responded to several fires in the county Wednesday afternoon, the sheriff's office said.

KVUE's Rebeca Trejo said that four different fires cropped up in the area.

Authorities said that crews were "making progress" on the fires located in the 1600 block of FM 535 near Thousand Oaks Drive. The largest brush fire was about 5 acres off of FM 535 near the Bastrop County line with Travis County. Firefighters contained it in about 45 minutes. At least five different fire departments -- including STAR Flight and Travis County first responders -- were dispatched to the area.

Crews also responded to a 2-acre fire on Synergy Drive. No homes or people are threatened. No firefighters were injured either.

The fires are contained and firefighters are working to put out hot spots.

FM 535 and Thousand Oaks Drive were closed for much of the afternoon due to the smoke.

Although a cause for the fires has not been determined yet, firefighters said the hot and dry weather is dangerous.
