WESTON — Multiple fire crews responded Monday afternoon to a grass fire in Weston that appears to have started in the median of Hwy. 29 at Hwy. J.

Flames quickly spread across the highway and headed toward the Weston Industrial Park and subdivision, witnesses said. Crews from South Area Fire District activated a multi unit box alarm or MABAS, to deploy additional units from Kronenwetter, Riverside, Ringle, town of Easton and town of Wausau along with the Department of Natural Resources.

About five acres burned before the flames were put out, officials said.

Fire danger remains high in Marathon County on Monday and officials are warning residents to use caution when handling flammable materials. Officials say even the flick of a cigarette from a vehicle window could prove extremely dangerous, especially under such dry conditions.

The Weston grass fire is one of dozens reported within the past 48 hours throughout the state, much of which is under a red flag warning.

No injuries were reported in the blaze, which has been extinguished.
