Update, 11 p.m.: Expressway in Dorchester at a complete standstill in both directions; six cars collided on the Zakim.
Drivers unaccustomed to powder-covered roads, coupled with a lack of salt, means spinouts and crashes are beginning to pile up. A Hummer ran up into a house on Lake Street in Brighton, but did no major damage to either house or people. Police shut Everett Street in Brighton after cars started playing pinball. Boston DPW salt trucks began blasting out of their yards to treat roads around 10:45 p.m.
Ed. note: I held off on raising the French Toast Alert based on a forecast that called for everything to melt by morning as temperatures rose into the 40s. I should have known better.
