New York Gov. Kathy Hochul declared a state of emergency starting Thursday in parts of western New York ahead of a potentially dangerous bout of lake-effect snow.

The National Weather Service forecast up to 4 feet of snow or more through Sunday that "may paralyze" the hardest-hit communities, including Buffalo, with periods of near-zero visibility.

Hochul's state of emergency covers 11 counties, with commercial truck traffic banned from a stretch of Interstate 90 southwest of Buffalo after 4 p.m. Thursday.
