*10 P.M. Update*
Four people including a pregnant woman safely escaped a mobile home fire Wednesday afternoon in the Kurten community of Brazos County.
But that fire then started a grass fire which spread to an acre.
Hot temperatures also made it dangerous for firefighters.
Fire crews raced to contain a fire that destroyed a mobile home in just a few minutes.
Two brothers, the brother's pregnant girlfriend and her 10-year-old son were all inside when they say they noticed the fire on the roof .
This happened in the 5000 block of North Oakland Lane in Kurten.
Laura Gurrero lives across the street.
She says the home was completely engulfed in less than 10 minutes.
Gurrero was driving home and saw smoke.
"Real, real sad because I think this is my house or something because I see only smoking. But when I see my neighbor oh my goodness I don't believe it," she said.
More than a dozen firefighters from across the county and Bryan and College Station responded on scene.
But Brazos County Precinct 3 Volunteer Fire Chief Gerald Burnett says there were challenges.
"We are in a volunteer fire district and it's broad daylight. So because it's daylight everybody's working for the most part, so folks have to take off work to come out here," Burnett said.
Near triple digit heat and high humidity didn't help.
"We're just making sure we don't get overheated and staying hydrated and setting up a rehab and having vehicles, command vehicles firefighters can get in out of the heat into the cool," said Lt. Mike Wodrich with the Bryan Fire Department.
While no one was injured, the fire destroyed the mobile home, a car, and badly damaged a vacant mobile home being used for storage.
"Real, real sad," added Laura Gurrero.
So far no word on the cause of the fire but fire investigators believe it was accidental.
Residents inside say the home was insured.
No injuries were reported.
Fire crews were working in the Kurten area in northeast Brazos County after a house and grass fires broke out Wednesday afternoon.
The fires were along Oak Lake Road southeast of Highway 21.
It is unclear how the fire started.
According to the News 3 crew on the scene, the house is completely destroyed by the fire. Residents told that crew that the fire started in their mobile home while they were inside. Four residents were able to get out ok - but they say the mobile home and connected garage were completely engulfed in matter of minutes.
That fire then spread to a nearby vacant mobile home, field and other mobile home.
Volunteer fire crews were able to contain and extinguish the grass fire within an hour. The grass fire ended up burning about an acre.
Crews from across Brazos County, including from Bryan and College Station, have responded.
Fire officials say the hot weather made it difficult for their team to stay cool as they fought the fire.
