Strong southwesterly winds are forecast to whip Western New York today with gusts as high as 60 mph.

And, it could result in a significant seiche on Lake Erie by raising the water levels on the eastern end of the lake by as much as 8 feet, forecasters said.
A high wind warning was posted through 5 p.m. for Erie County, along with Niagara, Orleans, Genesee, Wyoming and Chautauqua counties.
Shoreline areas of Erie County and Chautauqua County are also under a lakeshore flood advisory because of the expected seiche.
