CHARLOTTE, N.C. - Charlotte-Mecklenburg Schools will operate on a two-hour delay on Friday.
Buses will run routes and schools will open two hours later than the normal time.
It is the third time the extreme cold temperatures have caused CMS to open late this year. The district said the extra time allows workers to warm up the buses and classrooms.
The district delayed classes on Jan. 7 and 8 -- during record-breaking cold. At that time district officials said they had minor issues with heating and frozen pipes at a few schools, but that delaying classes helped things run more smoothly.
Earlier this month, the district said having a two-hour delay helped give bus drivers and maintenance workers more time to prevent any problems.
Wind chills to dip near zero in metro, minus 34 in mountains
Severe Weather Center 9 Meterologist Steve Udelson said the forecast low temperature will be 11 degrees with the wind chill around 1 degree.
Avery County Schools is closed while Burke County, Cabarrus County and Kannapolis schools will operate on a two-hour delay.
