Boston Mayor Marty Walsh said Boston Public Schools will be closed on Wednesday as the city digs out from Winter Storm Stella.

Boston schools were closed on Tuesday as well.

At a Tuesday press conference, Walsh said he didn't want school children walking on icy sidewalks and city streets, and he didn't want to risk putting buses on the roads. But city offices will be open, he added.

"It's coming down sideways so it's still a dangerous storm," Walsh said.

The city has seen 6 to 8 inches of snow so far, the mayor said.
