Welcome to Nassau County Emergency Management
Local Hazard of the Week: Winter Weather
Cold Weather Advisory - expect freezing temperatures during overnight hours through the weekend.
Anything that melts during the day can refreeze and create slick conditions on
bridges, overpasses, secondary roads, sidewalks, and driveways.
Be cautious if you must drive after dark or in early morning hours - icy patches are dangerous!
Let Emergency Management know what you are seeing - if you have snow and/or ice accumulation, upload your location and photos using the green button below.
