At the southeast corner of Lafayette and Spring in the SoHo-Nolita area, some sort of event (explosion?) occurred to knock off the heavy grates off the surface. The FDNY and NYPD closed down the street; it didn't look like a steampipe explosion or water main break (no water) - it looks more like an underground transformer vault (if anyone knows what these are, let us know in comments) explosion. The 6 line does run underneath, but there do not seem to be any delays.

Some of the bystanders speculated the snow and salt could have played a part in the explosion. And since this is the first substantive snow, that means possible electrocutions (dogs seem especially susceptible), though Con Ed has been working more aggressively to check stray voltage.
