(CNN) — Heavy snow is expected to keep piling up in western New York state through Sunday after a historic storm saw the Buffalo area logging record snowfall totaling more than 6 feet in some areas.

Just after 11 p.m. Saturday, the National Weather Service in Buffalo issued a special weather statement warning a band of heavy snow accompanied by high winds was creating a “burst of snow” in western New York state. The band was moving south of the Buffalo and Rochester metro areas, the weather service said.

By Sunday morning, winds shifted more westerly, meaning the heaviest lake-effect snow bands are now south of Buffalo impacting areas from Cleveland to Dunkirk, New York. Buffalo is no longer under a lake-effect snow warning but remains under a winter weather advisory through Sunday evening for “blowing snow,” according to the weather service.

While the Buffalo area is used to dealing with heavy snowfall, this storm is delivering “much more than we usually get,” Mayor Byron Brown told CNN Saturday.

Erie County, which includes Buffalo, experienced its largest-ever amount of snowfall in a 24-hour period Saturday, according to Erie County Executive Mark Poloncarz.

“This was a RECORD-BREAKING storm that in some ways was more intense than Snowvember, the relatively quick recovery is a testament to everyone’s preparation and planning,” Poloncarz tweeted. “The proactive approach continues to work.”

“Snowvember” refers to a storm in the Buffalo area in November 2014, where nearly 7 feet of snow was dumped in three days. At least 13 people died in that storm and the weight of the snow caused dozens of roofs to crumble under the impact.

Two people have died in this storm from cardiac complications related to shoveling snow and attempting to clear the ground, Poloncarz said.

As the heaviest snow slid south of the greater Buffalo area into southern Erie and Chautauqua counties overnight, an additional 6 to 18 inches is possible in the region, especially across higher terrain, CNN Meteorologist Derek Van Dam said.

The heaviest snowfall Sunday will be east of Lake Ontario, where up to a foot of additional snow is forecast with localized areas potentially seeing even more.

Winds could gust as high as 45 mph across the Great Lakes region, which will lead to very cold conditions with temperatures feeling like single digits to slightly below zero.

Record snowfall creates treacherous travel

An observation site near Orchard Park, where the NFL’s Buffalo Bills play, recorded a snow total of 80 inches since Thursday, according to a storm report from the National Weather Service.

This is the third-highest three-day total ever in the state of New York.

The multiday weather event has made travel in the region difficult, triggering the closing of roads, driving bans and flight cancellations the weekend before the Thanksgiving holiday.

On Saturday night, the weather service warned the latest band would make travel conditions severe in a matter of minutes.

Travel bans were in effect for much of Erie County, but as of Sunday morning New York Gov. Kathy Hochul tweeted many roads in Buffalo and Watertown have been able to reopen and “traffic is starting to move again!”

Nearly 400 citations have been issued to drivers who have been found violating travel bans in the region, Poloncarz, the Erie County executive, said.

“If you’re trying to enter an area where a travel ban exists, you will meet a friendly neighborhood New York State trooper who will immediately give you a ticket for violating the travel ban,” Poloncarz said.

The New York State Thruway Authority tweeted, “Crews are out this morning on the Niagara Thruway (I-190) removing #snow from the shoulders. We have large snowblowers like this working around the clock to clear snow. Please use caution if you are traveling today. The Thruway has reopened to all traffic.”

While officials earlier said some vehicles had to be towed after being stuck on the side of the road or involved in accidents, Hochul thanked New Yorkers who adhered to travel advisories and stayed home.

“Thank you for just following the directions, staying off the roads, and as a result, all the major thoroughfares are open now in western New York and the north country, with some limitation,” Hochul said at a briefing Sunday morning.

Air travel also has been snarled by the record snow, with dozens of flights arriving and departing from Buffalo Niagara International Airport canceled as storm conditions worsened, according to the airport’s website.

The airport set a daily snowfall record of 21.5 inches Saturday, shattering the previous daily record of 7.6 inches set in 2014, the local weather office said.

It ranks as the fifth-highest single-day snowfall total on record for Buffalo and the second-highest single-day snowfall total for the month of November.

This month is already Buffalo’s third-snowiest November at the airport thanks to the storm, according to the local weather service office.

Governor touts storm preparedness

Hochul thanked local and state agencies for their preparation efforts in western New York for storm preparations after a record dumping of snow, as the region is forecast to expect more this evening.

Speaking at a storm briefing in Jefferson County on Sunday, Hochul said the area in upstate Oswego County is expecting another 2 feet of snow by 7 p.m. tonight, at a rate of around four inches per hour.

Hochul said, “This has been an historic storm, without a doubt, it’s one for the record books. And as someone who is from Buffalo and has lived in upstate my entire life, we’ve seen a lot of snow.”

Around 1,200 people have been impacted by power outages in the state. Hochul said this is a manageable number and “no one has been in the dark a long time.”

The governor said, “Given the scale of this storm I’m really proud of how the utility crews have stepped up.”

On Saturday, Hochul said she was doubling the number of New York National Guard members on the ground in Erie County to check on residents and help with snow removal.

She also signed a request for federal reimbursement through a Federal Emergency Disaster Declaration.

Nearly 6 million people across four Great Lakes states (Michigan, Ohio, Pennsylvania, and New York) will remain under winter weather alerts through much of Sunday.

Brown, the Buffalo mayor, said the city could return to “some sense of normalcy” by Monday or Tuesday, assuming the worst of the storm passes through Sunday.

“This has been a very unpredictable storm with the snow bands moving, back and forth, north to south,” Brown said. “The snow has come down very fast, very wet, very heavy.”
