Emerson will hold all in-person classes before 10 a.m. Tuesday via Zoom as a nor’easter continues to pummel the city of Boston with snow, rain, and high winds. 

The decision was announced via a Monday night email and serves as an extension of the policy set into place Sunday night for Monday’s scheduled in-person classes. All campus buildings will be open for normal hours, the email said. 

Snow began to envelop the city Monday afternoon and is projected to continue into early Tuesday morning. The National Weather Service implemented a winter storm warning for Boston, which remains in effect until Tuesday at 5 a.m. 

Boston is expected to receive six inches of snow overnight, the Weather Service said. One inch of snow was projected to fall between the hours of 4 p.m. and 7 p.m.
