The Charlotte Area Transit System said it will end its bus service at 6 p.m. Wednesday because of the storm.
CATS said its light rail service will continue on its normal schedule.
Earlier in the day, around 1:30 p.m. CATS stopped running its Express and Regional Express buses. Those buses serve neighboring counties as well as parts of Mecklenburg. CATS stressed that several local bus routes that provide service along portions of Express and Regional Express routes are still running.
