A large smoke plume visible from Napa County on Sunday was produced by a Solano County brush fire and is no threat to local residents, according to authorities.
The smoke column was seen in the southeast portion of Napa County, the county Office of Emergency Services said in a Nixle alert. The blaze broke out Sunday morning near Vaca Valley Parkway and led to a shutdown of nearby Interstate 505 near its junction with I-80 in Vacaville, according to the California Highway Patrol.
I-505 and its connector ramps to I-80 reopened Sunday afternoon.
The Vacaville-area vegetation fire was one of two reported in Solano County. A second blaze east of Suisun City forced the closing of Highway 12 between Branscombe and Walters roads, CHP said.
Since Saturday night, Napa County and much of the Bay Area have been under a red flag warning issued by the National Weather Service for winds up to 50 mph that could cause fires to spread more quickly. The warning remains in force until 9 a.m. Monday.
Information from Bay City News Service was used in this report.
