It's official, weather experts believe the Hudson Valley is going to see its first major snowstorm of the season.

The National Weather Service issued a Winter Storm Watch from Thursday afternoon until Friday afternoon for Dutchess, Ulster, Greene, Columbia and Delaware counties.

A Winter Storm Watch means there is potential for significant snow, sleet or ice accumulations that may impact travel.

A heavy mixed precipitation is possible. Total snow accumulations of 2 to 6 inches and ice accumulations of up to one-tenth of an inch is expected, officials say.

The National Weather Service issued Winter Weather Advisories for Orange, Sullivan Putnam, Rockland, and Westchester counties from noon on Thursday until Friday.

2 to 5 inches of snow and about two-tenths of an inch of ice is expected in those areas, according to the National Weather Service.

A Winter Weather Advisory means that periods of snow, sleet or freezing rain will cause travel difficulties.

All Hudson Valley residents are told to plan on slippery road conditions. The hazardous conditions could impact the afterschool and evening commute on Thursday and the morning commute on Friday.
