Saturday’s snow created a winter wonderland — here on Brandle Road in Guilderland.

But the snow predicted to fall Monday night through Tuesday is expected to be more of a Nor'easter nightmare.

On Monday afternoon, Albany County Executive Daniel McCoy announced a state of emergency would go into effect countywide at 8 p.m. because of the possibility of “falling and drifting snow, high winds … sustained and low visibility over a period of time, causing dangerous road conditions that may pose a threat to public safety.”

The town of Guilderland, in anticipation of power outages, announced that, starting Tuesday morning at 10 a.m., warming stations will be open at two firehouses in town: in Westmere at 1741 Western Ave. and in Guilderland Center at 30 School Road.

Also on Monday, Governor Kathy Hochul held a press briefing in Latham during which she urged New Yorkers to stay safely at home during the storm on Tuesday.

“This will be a dangerous storm, said Hochul. “Please stay off the roads for your own safety. Stay in your homes, also for the safety of these incredible men and women throughout Upstate New York who will be giving up their time, working around the clock to make sure that the roads are plowed.

Hochul said 100 National Guard members have been positioned in eastern New York, which is expected to be hardest hit, and that utility crews have been positioned as well — nearly 8,000 workers, with 2,000 brought in from outside.

A state of emergency begins at 8 p.m. Monday, Hochul said, noting about eight inches is predicted for Monday night in the Finger Lakes and Western New York, which she called “manageable.”

“But then it intensifies,” she went on. “So one to two inches an hour. Three inches an hour, which is a lot … Monday night through Tuesday afternoon.”

New York City and Long Island are expected to get a “couple of inches of snow, and also we're watching coastal flooding on Long Island,” said Hochul.

The expected snowfall is complicated, she said, by winds upwards of 45 miles an hour, “and that’s when you get the lack of visibility and the inability for us to drive safely on the roads with the plow.”

She also said “So the snow is also going to be very heavy …. it’s going to take down the wires. There's no way around it. When you have snow, that's 50 percent heavier than normal, this is not the light fluffy, pretty Christmas snow. This is going to come down like a brick …. So one and a half feet of snow is going to have the effect of three feet of snow.”

Hochul said “widespread power outages in a very large geographic area” are expected.

She added, “I’ve ordered all state employees in the Capital Region who have the ability to work from home in the Capital Region, Mid-Hudson to work from home tomorrow. So we're encouraging other employers to follow suit, especially with the ability to Zoom into your jobs. We're encouraging people to please stay home and off the roads.”
