VALLEJO (CBS SF) – Vallejo City Unified School District has closed its schools for the rest of the week because of a large amount of smoke from the North Bay wildfires, district officials said Wednesday.

Monday was a previously scheduled professional development day for the district, so students will return to class on Tuesday, district officials said.
