Cool weather helped firefighters contain small wildfire in northeast Sonoma County

Low temperatures and high humidity helped fire crews quickly extinguish a small wildfire east of Geyserville on Monday night.

The Wilson Fire, which was reported at about 9:40 p.m. in the 3000 block of Geysers Road, was contained to just over 8 acres, with help from cooler weather that slowed its spread as the flames moved beneath the tree canopy, Cal Fire Battalion Chief Marshall Turbeville said.

The temperature was about 70 degrees when firefighters responded and winds were calm, Turbeville said.

“We were really fortunate that the weather helped us with containing the fire,” he said.

The fire sparked just off the road on private property and burned open grass, trees and logs in an area that burned in the 2019 Kincade Fire, Turbeville said. No structures were damaged.

The fire was contained and knocked down by about 10:45 p.m. and crews were on site until 2 a.m. mopping up, he said.

The cause of the fire is still under investigation.

Neighboring property owners reported seeing fireworks, though it’s not clear if that may have caused the fire.

The fire could’ve also been started by a vehicle stopped on the side of the road or a vehicle operating on a flat tire, where the rim makes contact with the ground.

Four engine crews with Cal Fire and Northern Sonoma County Fire responded to the fire, along with a neighbor who brought their water truck, Turbeville said.
