He said more than 200 employees will be battling the storm, adding that the county had more than 100 assets, including plows and spreaders, out in the streets. The county also has on hand more than 13,000 tons of salt.Suffolk officials said the county had a fleet of more than 300 vehicles working on snow removal and spreading salt across county roads. The county has in stock between 16,000 to 18,000 tons of salt and sand, a county spokeswoman said.“The roads can be treacherous due to the snow accumulations as well as the freezing conditions,” she said. “We want people to be very careful as they’re traveling on the roads.”The county also announced that its bus system, Suffolk County Transit, will cease operations at 6 p.m. Tuesday and will start up again at 8 a.m. Wednesday.The cold is also expected to be a factor because of an arctic air mass that moved into the region. The arctic air mass, which breaks off and travels south, should send temperatures plunging into the teens. Forecasters also warned that strong sustained winds and gusts topping 35 mph could produce a wind chill of 10 degrees below zero.Tell us on Facebook: Sign up for our COVID-19 newsletter to stay up-to-date on the latest coronavirus news throughout New York A winter storm barreling toward Long Island will drop up to 14 inches of snow on the region, the National Weather Service said.
