Most immediately, that means no parking on designated main roads - towing begins promptly at noon, so look for free or low-cost parking. BPS kids who normally would go to school will instead have to fire up the Zoom screens - and all students will be released from classes 2 1/2 hours early. BPS meal sites will be open on Monday, but BYCF meal sites will not.

This could be Mayor Walsh's last snow emergency in Boston. No word yet if he'll remind us this isn't Loon Mountain, you know, for old time's sake.
Also, the snow emergency means you get to fiercely defend your on-street parking space for up to 48 hours after the snow emergency is called off (except in the South End, where you're never supposed to try to save a space).
