8:33 PM: Firefighters are arriving at a house fire in Arbor Heights near 34th and 102nd (map), reporting black smoke and also that ammunition is going off in the house – so they’ll be fighting it from outside.

8:38 PM: Scanner now indicates they don’t believe there’s more ammunition in the building and they are changing firefighting tactics.

8:48 PM: Our crew is at the scene. No word yet on whether anyone’s been hurt. They believe everyone in the house got out safely.

8:58 PM: Just talked again with our crew at the scene. The fire appears to be under control but there are still flare-ups of flames visible here and there. Way too soon to know what caused it.

Above this line, we’ve added a quick Instagram clip – you can see firefighters on the roof and hear the saws they’re using to ventilate the attic.

9:18 PM UPDATE: We’ve just talked again with firefighters. The fire began in a bedroom and spread up to the attic. The house has major damage and isn’t inhabitable. One person was inside when it started, and we’re told he got out OK, unhurt. The “ammunition going off” suspicion is now a mystery – we’re told the resident said there had been firearm(s)/ ammunition in there, belonging to a renter who moved out a few weeks ago, so whatever the bangs/pops were in the early going, they now don’t know. SFD’s investigator is en route to work on figuring out how the fire started.

ADDED 11:16 PM: From SFD: “Cause of West Seattle Arbor Heights fire is man using spray paint can & lighter to try and kill spider in the wall. Damage estimate $60k.”
