The Los Rios Community College District will close all four college campuses and its district office through Sunday, according to LRCCD public information officer Gabe Ross.
Campuses will be closed and all classes are canceled. The closure includes American River, Cosumnes River, Folsom Lake and Sacramento City colleges.
Students were informed about the campus closure with a text message from the district alert system.
“Regional air conditions have not improved as anticipated, so Los Rios colleges are canceling all classes effective immediately and through the end of the week,” the text read.
