PSEG Long Island officials said the power utility is prepared to respond safely to potential power outages.
While powdery snow associated with extreme cold typically does not damage electrical equipment, the utility said hazardous driving conditions, icy roads and reduced visibility could lead to vehicle collisions with utility poles.
Crews and resources will be in place to respond as quickly and safely as possible. Michael Sullivan, vice president of electric operations, said the company continues to monitor the storm and has completed system and logistics checks to support timely restoration efforts.
The utility urged customers to prepare in advance, including knowing how to report outages and follow winter safety guidance. PSEG advises people to stay away from downed wires, which should always be considered live, avoid standing water or slush, and never use generators or gasoline-powered equipment indoors or near windows or vents.
