A winter storm watch is in effect from late tonight through Friday afternoon.
The National Weather Service issued the watch and said significant snowfall could hit the region by Thursday morning, lasting well into Friday. (Correction: In original version, we said a watch was more significant than a warning. The opposite is true. A warning is more severe than a watch.)
It's too early to predict the amount of snow that could be dumped on the area.
"Those planning to travel during this period should monitor the latest weather forecasts for updates to this developing storm," the service said in its bulletin.
An AccuWeather press release, according to the D&C, is calling for a "hurricane" level snow storm to hit the Hudson Valley and spill into the Rochester area.
"It's going to be a very nasty storm," said Alex Sosnowski, a meteorologist with AccuWeather.com, a weather service based in State College, Pa.
An AccuWeather press release said the storm "will be nothing short of a monster" and "may seem more like a 'snow hurricane' than a blizzard."
