Municipal and state crews across Nassau County geared up for a winter storm with heavy snowfall, particularly to northern parts of the county.

Officials say conditions could deteriorate rapidly once the storm arrives. Highway departments across Long Island have already begun preparations, loading salt and pre-treating roads to reduce hazardous conditions.

In the Town of North Hempstead, highway workers were seen loading a shed with salt ahead of the storm, which could dump up to a foot of snow in some areas. Town Supervisor Jennifer DeSena said all highway staff was called in to ensure roads remain passable throughout the holiday weekend.

“We get the brine down on the pavement,” DeSena said. “That helps melt the snow when it lands, so we’ll have a better result.”

Roads in the town were treated early with a brine solution, a mixture designed to prevent snow and ice from bonding to pavement.

Glen Cove is also expected to see significant snowfall. City crews have begun pre-salting roads, and Mayor Pamela Panzenbeck urged residents to keep streets clear to allow plows and salt trucks to operate safely and efficiently.

“We ask that all cars are off the streets and go to the municipal parking lot, park in their driveway or on their lawn,” Panzenbeck said. “It’s much easier and safer for our crews to do their work if there are no cars on the streets.”

Additionally, the special garbage pickup in Glen Cove has been canceled for Saturday.

At the state level, crews are monitoring the storm closely. Gov. Kathy Hochul declared a state of emergency for both Nassau and Suffolk counties, which would allow additional resources to be deployed.

“If we’re low on salt, I can procure more salt supplies if necessary in an emergency situation,” Hochul said. “We’re considering that option right now, but we’re going to keep an eye on the storm.”

Nassau County Executive Bruce Blakeman declared a state of emergency on Friday night due to the winter storm.
