City agencies are getting ready for Friday's snowstorm, and they are asking residents to use caution if they're heading out. Between 4 to 6 inches of snow is forecast for Friday into Saturday, making travel tricky especially for those coming and going during the holiday weekend. Gov. Kathy Hochul has declared a state of emergency in New York City.

The MTA says it is ready to use emergency response equipment, including debris and de-icer trains, to clear tracks during the storm Friday and Saturday. Officials say they are keeping an eye on the nearly 220 miles of outdoor track, particularly in the Rockaways, Sea Beach, Flushing, Brighton and Dyre Avenue.

More than 3,600 buses have been outfitted with snow chains on their rear wheels to provide better traction. The MTA warns that bus service will be adjusted based on road conditions around the city and changes on a route-by-route basis are possible.

Access-A-Ride will operate on a normal schedule.

The New York City Department of Sanitation has issued a snow alert. A snow alert is the department’s higher level advisory during winter operations.

City officials said highway brining began Friday morning to help reduce accumulation on roadways.

No changes are anticipated for collection operations Friday and Saturday, but delays are possible, officials said.

When a plowable depth of 2 inches or more is reached, residents can go to nyc.gov/PlowNYC to track the progress of DSNY snow removal vehicles.

The Sanitation Department will clear streets and bike lanes, but residents are responsible for shoveling sidewalks.

New York City Emergency Management said travelers should expect delays and allow more time to reach their destination.

There is no anticipated change to trash collection operations Friday and Saturday, and New Yorkers should continue to follow their regular schedule for trash, recycling and compostable material, according to DSNY.
