For much of the north country, the first snowstorm of the season is over.
But in parts of Lewis and Oswego counties, the snow kept piling on Friday afternoon.
At one point, radar showed snow falling at a rate of 3 to 4 inches an hour.
Port Lyden, which caught some of the worst weather, had just under 18 inches of snow Friday afternoon.
Carthage had 14.5 inches, Harrisville 12 inches and Watertown 11 inches.
7 News weathercaster John Kubis said the intense lake effect snow was likely to continue in southern Lewis County until early Saturday morning.
Adding to the woes of drivers: winds that can gust up to 35 miles per hour.
"Travel will be extremely difficult within the lake effect snow with near zero visibility at times and very poor road conditions," according to the National Weather Service.
7 News reporter Alexandra Field found whiteout conditions on Route 12 between Lowville and Copenhagen. (Our pictures are from Lowville.)
In particular, Route 81 between Parish and Adams will be tough going, as will routes 177 and 12 and 26.
The usual cautions apply: don't travel in these areas if you can at all avoid it, and if you must have a full tank of gas, extra clothing and blankets with you.
The worst of the snowfall ended in Watertown late Thursday, and there were far fewer cancellations in central and northern Jefferson County - and St. Lawrence County - than Thursday.
Overall, a lake effect snow warning remains in effect until 1PM Saturday.
National Grid initially reported widespread power outages in Jefferson County, with more than 2,900 customers out of power.
