ORIGINAL 8:35 PM REPORT: Just mentioning this because so many have e-mailed and texted about it. We also saw the apparent smoke that, according to the 911 log, came from the Ash Grove Cement facility on East Marginal Way (map). It was originally a “fire in building” call; however, the call was already “closed” less than half an hour after it started. So what was it? No info yet but we’ll try to find out. That may be tough – we just reached someone who answered “control room” at the plant, and as we started to identify ourselves as news media, they said “You’ll have to call back Tuesday morning” and hung up.
ADDED 9:04 PM: From Dan Berger, the photo above and this note:
Driving south on E. Marginal on my way back to W. Seattle @ 8:05 pm. I observed a large plume of ash pouring out of the top of a silo at the Ash Grove Cement plant. The plume completely obscured visibility down E. Marginal past the plant. Attached is a photo taken about 15 min. later, with the cloud subsiding. At this point there is now just a wispy haze south of the plant. No idea how much dust coated the neighborhood.
We have just driven past the plant on East Marginal – we could see, from a distance, at least one fire truck getting hosed off near the plant’s entrance road. There’s definitely some dust being kicked up as we drive along East Marginal, but not enough to show on a photo.
ADDED 11:33 PM: We’ve received video from Michelle, shot while what looked like smoke was pouring from one side of the plant. Focus on the left side of one of the silos in the center of the frame:
If no information emerges sooner, we will be checking back on Tuesday, as suggested.
