Original story, 9:30 a.m.:

Bands of lake effect snow will affect Niagara, Orleans and northeastern Genesee counties this morning.

A lake effect snow warning continues for Wyoming County, and a winter weather advisory remains in effect for Monroe County.

At 8:39 a.m., bands of lake effect snow producing snow fall rates of more than 1 inch per hour and visibility less than one-quarter mile stretched from western Niagara County across much of Orleans county and into northern Genesee county, the National Weather Service said in a special weather statement.

Locations affected include Niagara Falls, Lockport, Medina, Albion, Hamlin Beach State Park, Newfane, Lewiston, Byron, Youngstown, Middleport, Holley, Waterport, Lakeside Beach State Park, Fort Niagara State Park, Sanborn, Point Breeze, Kent, Ridgeway, Shelby and Clarendon.

Conditions can deteriorate rapidly in winter weather situations. Be prepared for snow or ice covered roads. Slow down and allow extra time when traveling, the Weather Service said.

Lake effect snow was also continuing across portions of Interstate 90 in western NY this morning. Conditions will deteriorate rapidly in lake bands with visibility falling to less than a quarter mile.

In Wyoming County, a lake effect snow warning remains in effect until 10 tonight.

Additional snow accumulations of 6 to 10 inches are expected in the most persistent lake snows, according to the Weather Service.

Travel could be “very difficult,” the Weather Service said.

The lake effect snow warning was issued overnight, replacing a winter weather advisory.

A winter weather advisory does remain in effect until 6 tonight for Monroe County.

Additional snow accumulations of 4 to 7 inches are expected in the most persistent lake snows.

Travel could be “very difficult,” the Weather Service said.

There are no advisories for Genesee, Livingston or Orleans counties.

The forecast for Livingston County calls for total daytime snow accumulations of 1 to 2 inches possible, and new snow accumulation of less than a half-inch tonight.

A fresh Canadian airmass pouring across the partially ice covered lakes will continue to generate accumulating snows mainly southeast of the lakes through tonight. A large area of high pressure over the Ohio valley will then pass by to our south on Sunday to end the lake snows and allow abundant sunshine for the vast majority of the forecast area, the Weather Service said in a forecast discussion this morning.

Conditions will be notably milder for the first half of the new week as multiple pacific based systems will move through the region, according to the Weather Service.
