Updated: S curves are now reopened.
With wet snow falling rapidly, traffic conditions have worsened this afternoon, officals said.
Police have closed the "S" curves through the South Mountain Reservation, the stretch of South Orange Avenue between South Orange and into Millburn.
The county road is closed both east and westbound as of 3:45 p.m.
Readers report traffic snarls on many local streets, including Wyoming Avenue. Wyoming is reportedly crowded, possibly because South Orange Avenue is closed.
Trains and buses are cross-honoring today.
