The school system said it will be a Code A: Optional Teacher Workday for all employees.
"Safety of our students and staff is our number one priority," said Dr. Peter C. Gorman, superintendent of CMS. "Because this is such a large county sometimes there are weather issues in some parts and none in other areas."
Eyewitness News checked on conditions at Charlotte-area schools Sunday afternoon. At North Mecklenburg High School and Druid Hills Elementary, parking lots and walkways were covered in ice and snow.
Parents said they were worried any melting ice will be frozen by Sunday night and make for dangerous conditions.
"It's still all icy right now," Brian Huber said, father of two children. " (It's) definitely going to freeze tonight after the temperatures go down to what they say they're going to go down."
All after-school activities are also canceled. The CMS After School Enrichment Program (ASEP) will not be in operation Feb. 1. CMS new-employee orientation and all professional development activities are also canceled. The mid-year graduations that were scheduled for Feb. 1 at Bojangles Coliseum have been rescheduled for Tuesday, Feb. 2, at 5 and 6:30 p.m.
