Now (3:15am) at the one-hour mark, it's still an active fire, but fire command on site has declined help from an additional company, and are saying "condition the same, companies making progress."
At 3:20am calling for a "20-foot collapse zone around the building. Slate shingles coming off the room, eminent [immanent?] danger of the chimney collapsing."
(does that mean they evacuate the houses on either side, I would assume?)
From my house I can see that Willow is shut down, and the bike path, so expect a similar 4 block radius.
