As a result restaurants are ordered to be closed to outdoor dining starting at 2pm 'to protect the safety of patrons.'
The city will notify restaurants, which are already closed to indoor dining due to surging coronavirus cases, when they can reopen for roadway seating.
'Based on the current forecast, the City estimates that this Snow Alert will be over on Thursday evening, allowing restaurants to reopen, but this may change to the morning of Friday, December 18 based on actual accumulations and roadway conditions,' the city's sanitation department said Monday.
'At this time, the City is not asking that restaurants remove any barriers or structures for roadway dining,' the department added.
