UPDATE: Power began coming back on around 6:20 p.m.
Reports pouring in of power outages from across the city: Kendall, Central and Harvard squares all without lights. Cambridgeport is dark. The Cambridgeside Galleria and the Museum of Science? Powerless. Even the Harvard Business School across the river might be out.
Cambridge Police  report:
NStar says major transmission line failure to blame for the power outage in Cambridge. Will take several hours to fix.
The short might be in Central Square. Prairie Rose Clayton tweets :
Just biked through Cambridge. Central/Kendall all dark. Central smells heavily of ozone.
NStar reports  28% of the city is without power. Area 4 and Inman Square are OK.
The Red Line is dead, although a T spokesman denied a Twitter rumor that it was due to a deer getting hit at Kendall Square. "The Red Line is underground in Kendall Square," he said. Still, MBTADeer  quickly sprang up.
Michelle, stuck on a 66 bus, tweets :
Major kudos to my MBTA bus driver who just asked us all if we'd just all like to go to the bar instead.

In the Boston Store :
Our tees are soft and comfy. They run a little small, so size up for a looser fit.
