11:40 AM: A sizable Seattle Fire response has headed back to the 10000 block of 39th SW, scene of two fires at one house in a little more than a week. (update) First crew on scene says “no fire, just smoke” – so they’re putting water on it.

11:52 AM: Our crew on scene says the smoke is mostly coming from the back of the house (added, photo showing new fencing in back):

No flames seen so far, as noted previously.

12:09 PM: For reference – the first fire was on April 29th; second one, early Monday morning. The cause of the first one has yet to be determined; one of the home’s two residents, both said to be in their 70s, was still in the hospital at last report.

4:42 PM: As AG notes in comments, SFD announced this afternoon that overheated wiring caused the original fire on April 29th and that “residual embers” were to blame for the flareups today and two days ago.
