A deadly lake-effect snowstorm dumped more than five feet in parts of western and northern New York on Friday. 

In Erie County, officials said the storm was blamed for the deaths of two men who passed away after suffering cardiac heart attack events while shoveling and using a snowblower.

The county did not know of any others who had died as of Friday night and Erie County Executive Mark C. Poloncarz offered his condolences to the family and friends of the deceased, advising residents to "shovel smart" in the heavy, wet snow. 

However, more snow was expected to fall on Saturday after hitting southern towns in the county "with a vengeance."

Authorities had problems with trucks that jackknife and the Department of Public Works said stuck vehicles and tractor trailers were reported "all throughout the county." 

"This is the problem we have been dealing with across the Southtowns. This is Abbott Road and Lake Avenue in Hamburg/OP. Tractor Trailers that are rarely on this road tried to get around the Thruway closure and got stuck. This is why we can't get to secondary roads/neighborhoods," Poloncarz tweeted Saturday morning, noting that Erie County Department of Homeland Security and Emergency Services Commissioner Daniel Neaverth Jr.said he was "cautiously optimistic" the area is through with the worst of the storm" and that assets were "in place or on their way to assist" with response.

Up to three inches of snow fell per hour late on Friday and flights out of Buffalo were delayed or canceled then.

Snow in Buffalo was accented by occasional claps of thunder, as seen in videos posted to social media.

The storm’s severity varied widely due to the peculiarities of lake-effect storms, which are caused by frigid winds picking up moisture from warmer lakes and dumping snow in narrow bands.

This all comes as New York City got its first feeze warning of the season.
