New York Gov. Kathy Hochul issued a winter storm advisory and advised people to avoid any unnecessary travel in several parts of the state.

"Areas in Western New York and the North Country are already experiencing lake effect snow and we're anticipating up to six inches of snow in Downstate regions between tonight and tomorrow morning," Hochul said in a statement.
A winter storm is headed for the Interstate 95 corridor, where earlier this week, weather conditions left people trapped on the highway for more than 24 hours in Virginia.

Dozens of schools announced they will be closed on Thursday due to weather conditions, according to Memphis ABC affiliate WATN.
