warning 
Special Weather Statement issued February 28 at 2:34AM EST by NWS Upton NY (Region Impacted: Western Passaic; Eastern Passaic; Hudson; Western Bergen; Eastern Bergen; Western Essex; Eastern Essex; Western Union; Eastern Union; Orange; Putnam; Rockland; Northern Westchester; Southern Westchester; New York (Manhattan); Bronx; Richmond (Staten Is.); Kings (Brooklyn); Northwest Suffolk; Northeast Suffolk; Southwest Suffolk; Southeast Suffolk; Northern Queens; Northern Nassau; Southern Queens; Southern Nassau)
Areas of fog have developed over portions of the region and are expected to expand early this morning, lingering into mid- morning. At the same time, temperatures in most spots will be at or below freezing. This combination, along with any refreezing of melted snow, could result in slippery conditions of untreated surfaces due to black ice. Use caution if traveling this morning as black ice can make conditions very slick. Locally reduced visibility will be possible as well. Leave extra room between you and the car in front of you. Additionally, pedestrians should use caution walking on any untreated surfaces.
