At 11:30AM a blast near Polk and O'Farrell streets resulted in flames coming out of a manhole and 8,600 PG&E customers without power. The fire couldn't be contained for more than two hours. No injuries reported yet, although fire fighters did respond to some folks being stuck in elevators. Police immediately closed off a two-block radius, and advised residents to stay indoors with the windows shut to avoid inhaling any of the fumes. They still don't know what caused the fire, mostly because they can't get down to the source. "Firefighters at first used foam to fight the blaze, but backed off when PG&E officials asked them to let the fire burn out. Once they stopped, the black plume was replaced with roaring orange flame, reaching 30 feet at one point." The fire drew such a crowd, that Mayor Gavin Newsom and Police Chief Heather Fong showed up. Got plans in the TL tonight? Cancel 'em.
