BASTROP COUNTY, Texas (KXAN) — An "extremely active" wildfire in Bastrop County started causing mandatory evacuations Sunday, according to county officials. Several residents are still away from their homes Monday morning as crews continue working to contain the fire. The Bastrop County Office of Emergency Management said the Hudson Fire is south of Park Road 1C. This is between Bastrop State Park and Buescher State Park. Evacuation checklist: What to grab when evacuating The Texas A&M Forest Service said Monday morning the wildfire was started by a structure fire nearby. According to the forest service, the fire was at 400 acres and was 30% contained as of Monday morning. Officials said the Hudson Fire is moving north because of strong south winds.

(KXAN Photo/Todd Bailey) Kari Hines with the Forest Service said during a Monday morning news conference that firefighters remained on scene overnight and constructed a bulldozer line around the entire perimeter of the fire, meaning crews had cleared a path in vegetation where firefighting equipment is set up to work to contain flames. Crews will keep working on mop-up and containment throughout Monday. Hines said the weather helped overnight because humidity increased to 100%. Evacuations were still in place Monday morning for residents in between Alum Creek Road and Cottletown Road along Park Road 1C and Gotier Trace Road, according to Hines. The timeline for those people to return home is dependent on fire activity and weather Monday, as thunderstorms are expected to roll in and may affect response throughout the day, Hines said. Initially there were about 60 homes evacuated on Sunday, but many of those residents were able to return home. As of Monday morning, there were about 20-25 homes still evacuated, according to Hines. Sunday updates, response details The Texas A&M Forest Service previously said the fire was at 15% containment at 9:55 p.m. Sunday night. "We've had a fairly fast wind-driven fire today," Hines said on Sunday. "We'll be rotating people and making sure people are getting the rest they need. We do expect to be continuing operations throughout the evening and into the night." Hines said that while dry and windy conditions exacerbated flames Sunday afternoon and evening, the weather is expected to improve overnight and into Monday. "The forecasts show that our wind gusts are going to be decreasing and our humidities are coming up overnight. We also expect humidities to be higher in general tomorrow," Hines said. "We're looking forward to being able to do some really good work around containment this evening," she continued. Evacuation information About 60 homes near the fire were evacuated Sunday, according to Texas A&M Forest Service. Of those, about 20 to 30 were directly threatened. "Thankfully, this fire is not burning in an area that is very highly populated," Hines told KXAN. As of Monday morning, evacuations are in place for residents on Highway 71 between Alum Creek to Goiter Trace and residents on Park Road 1C between Alum Creek Road and Cottletown Road. Evacuees can shelter at the Smithville Recreation Center starting Sunday at 6:30 p.m. This is located at 106 Royston Street. A temporary animal shelter for dogs, cats and small animals is set up at Mayfest Park. Bastrop County Agrilife Extension is also setting up livestock assistance at Mayfest Park. There were still road closures along Park Road 1C and Gotier Trace Road Monday morning. Wildfire battle Local emergency responders and agencies from other areas responded to the fire and are expected to be on scene throughout Monday, according to the Texas A&M Forest Service. Aviation resources are also on standby Monday, Hines said. On Sunday, fire crews used heavy equipment to create containment lines on the southern border of the fire, and aviation crews helped, as well as fire trucks protecting threatened structures. "October is supposed to be one of our wettest months, and of course, it was not," Hines said. "We have what we would consider a high-risk fuel type when it's dry."

Greg Abbott said over 90 personnel and 60 assets, including air tankers and fire engines, were deployed to the Hudson Fire. This is a developing story and will be updated.
