BOSTON (CBS) — It’s not safe to be on Boston roads following another record-setting snowstorm, Mayor Marty Walsh said Sunday.

“It’s very, very dangerous out there today,” Walsh said in a Sunday morning news conference. “I just ask people to stay off the roads today.”

The city has seen more than seven feet of snow in 23 days. This winter is already the third-snowiest ever recorded in the history of Boston.

“I don’t know what to say to anybody anymore,” Walsh said. “Hopefully it will stop eventually.”

A parking ban will remain in effect in Boston until further notice, and Walsh said 200 cars were towed overnight. Close to 600 plows are on city streets, trying to clear snow.

Boston has blown past its original snow budget of $18 million. This storm will add about $7 million, Walsh estimated, bringing the total for this winter up to nearly $33 million.

“At this point I’m not concerned about the budget for snow plowing, I’m concerned about making sure people are safe,” Walsh said.

The mayor said the city has seen an uptick in carbon monoxide incidents, and urged people to check on elderly neighbors. He also warned of the danger of roof collapses, and said residents should get a contractor if the need to remove snow.

The city has also made many South Boston streets one-way due to the unprecedented snow.
