The snow began to fall this morning in a storm that is expected to bring 6 to 10 inches of snow across Fulton and Montgomery counties by Friday morning.
National Weather Service meteorologist Luigi Meccariello said the storm will pick up in intensity today.
Higher amounts of snow will fall to the southeast of Fulton and Montgomery counties, Meccariello said.
Around 9 a.m. today, the snow was making its way north and brushing over western Saratoga near the Fulton County line, he said.
Meccariello said the storm came from the northeast coastline. The heaviest snowfall will start during the evening commute today, he said.
During the worst of the storm, snow will fall at up to an inch per hour. The storm should bring only snow, he said.
"A little after the evening rush hour is when it's really going to intensify and then continue into the early hours of Friday morning before tapering off to light snow," Meccariello said.
He said the temperature today will remain in the mid-20s with 15 mph winds, and the overnight temperature will fall to the lower 20s. On Friday, he said, the temperature will warm up to the lower to mid-30s.
Several schools across the two counties had early dismissals today because of the snow. Among them were the Broadalbin-Perth Central School District, Mayfield Central School District, Northville Central School District, Oppenheim-Ephratah-St. Johnsville School District, Greater Amsterdam School District, Canajoharie Central School District and the Fonda-Fultonville Central School District.
In anticipation of significant snowfall, the city of Amsterdam declared a snow emergency.
According to a news release, the snow emergency requires that all motor vehicles be removed from Amsterdam streets by noon. Any vehicles on city streets after that time will be subject to being towed. Vehicles must remain off the streets until the snow emergency is lifted, the release said.
Amtrak canceled some of its trains and modified the schedules for others because of the winter storm.
The majority of flights scheduled to leave Newark Liberty Airport were canceled.
