Total snowfall of 15 to 20 centimetres expected this afternoon and tonight.
A snowfall warning has been issued for Pictou County. Another storm is expected to start this afternoon and dump between 15 to 20 centimetres of snow on this regoin.
According to Environment Canada, a low pressure system will develop south of Long Island this morning then track northeastward to pass south of Nova Scotia tonight. Snow ahead of this system will start this morning over Western Nova Scotia then spread eastward through the afternoon.
Strong northeast winds will develop this evening giving local blowing snow before slowly diminishing by early Thursday morning. Strong northerly winds will persist over eastern sections of the province into Thursday morning.
The province has issued a release saying it has its snow plow drivers ready to roll.
"We have hundreds of staff and more than 400 pieces of snow-clearing equipment ready," said Barb Baillie, executive director of maintenance and operations, Transportation and Infrastructure Renewal. "We are maintaining our plowing standards during what has been a very busy and challenging season."
The department's standards are to have 100-series highways, trunk highways, and other high-traffic roads cleared within eight hours after a storm ends. Provincial plow operators work 24-7 during a storm, plowing roads as a storm is blowing, but often can't make headway until the snow stops. Secondary and other medium-volume roads must be cleared within 12 hours after a storm. Local roads, streets in residential areas and subdivisions, and gravel roads are cleared within 24 hours.
"It only makes sense to clear the busiest roads first," said Baillie. "If we're advised of a medical emergency through 911, we'll pull a plow off its regular route to assist emergency vehicles to get where they need to go."
The best thing drivers can do during a storm, they said, is stay off the roads, if possible, and let operators do their job. Road traffic packs snow, which turns to ice in colder temperatures, making the clean-up twice as difficult.
