Mayor Bill de Blasio said the snowstorm headed toward New York City Wednesday could be “the biggest storm in years” as he addressed snow prep protocol Tuesday. 

The National Weather Service issues a winter storm warning for the storm expected Wednesday at around 4 p.m. 

The storm is expected to continue through Thursday morning with 50 mph wind gusts and blizzard-like conditions. 

Commuters are warned not to take their car into the city or anywhere Wednesday morning as the evening commute will be rough, the mayor told reporters Tuesday. 

The mayor is asking everyone to use mass transit or simply work from home if possible. Mayor Bill de Blasio says he hopes outdoor dining will be back up and running by Thursday evening. 

Vaccine delivery and storage will not be disrupted by the storm, according to the mayor. 

Alternate side parking will be suspended on Wednesday and Thursday. 

Food deliveries can continue, and the mayor says schools will open for both in-person and remote learning as well as school bus transportation on Wednesday. 

The mayor says a hazardous travel advisory is set to be issued Tuesday. He urged drivers to avoid unnecessary travel. 

A code blue will also be issued for homeless New Yorkers, and H+H testing sites will close Wednesday at 2 p.m.
