At least two manholes caught fire after exploding on Water Street (between Adams and Washington Streets) and on Washington Street in DUMBO around 3:15 today. One witness tells us "one of the manhole covers flew several stories off the ground. There was fire before but now just a lot of black smoke." The FDNY seems to have the situation under control, and there don't appear to be any injuries reported, but when something similar happened last month in midtown, Thom Yorke fans were tragically inconvenienced.
