Dry conditions sparked concerns on Saturday after a grass fire spread too close for comfort for some Los Fresnos neighbors.

No homes were affected by the flames, but the fire burned 185 acres.

Socorro Vega learned about a fire near her Del Mar Heights home through a phone call from one of her sons.

"We thought it was straight ahead, but when we arrived, it was this way over there," Vega said.

About a mile away, at least 30 firefighters battled the flames under challenging weather conditions.

"It is a very challenging fire because there is a fire danger warning today and very dry conditions. Fortunately, no structures are in danger right now, and we have it contained to one area," Brownsville Fire Chief Jarrett Sheldon said.

Sheldon said the Brownsville Fire Department was called in to assist the Los Fresnos Fire Department around 1 p.m. Saturday.

"We did have a wind shift midway through the fire, and at that point we did change our tactics," Sheldon said. "For the most part, it burned up to a canal area on one side, and now we're working on the other side of the fire."

Sheldon said the type of grass and the terrain also made firefighting difficult.

"It's a very challenging type of grass for firefighting, and the terrain is a little difficult. There are some areas we're burning, and the wind shift didn't help," Sheldon said.

As the hours passed, Vega says she could see the cloud of smoke continuing to grow.

"I told my husband I was going outside to water my plants, but I noticed the smoke rising again. I told him, 'look, it's rising again,' and he said it's because of the wind," Vega said.

While the fire never reached her neighborhood, Vega says the conditions still worry her.

"Imagine everything is so dry. Can you imagine if it catches more and more fire? You worry because the wind can pick up and spread it. Sometimes pieces of wood fly through the air, and that causes even more burning," Vega said.

Despite concerns, fire crews were able to contain the fire.
