Let's check out the advisory...
The New York City Department of Sanitation has issued an agency preparedness ‘snow alert’ for Monday, December 28 at 8 p.m. A snow alert is not a weather forecast, but indicates the potential of a snow event. Calling a snow alert allows DSNY to begin to prepare for a possible response by loading salt spreaders, attaching plows (if necessary), preparing tire chains and notifying other city agencies and supplementary personnel as needed.
DSNY is coordinating with the Office of Emergency Management and the Department of Transportation on snow clearing protocol in accordance with each agency’s written snow plan. All relevant city agencies have been notified of the snow alert. DSNY will continue to monitor forecasts and will provide updates as the snow event approaches.
Please remain vigilant.
