Shelley wrote this morning that there was a loud boom at Third Avenue Northwest and NW 89th Street about 1:40 a.m. This morning she and neighbors noticed a fine white coating of dust on their house and vehicles.
I did a little exploration and the dust seems to have settled primarily in the five or six houses surrounding ours. It blew off my car easily as I drove and seems to be a fine clay or similar. Can’t imagine what that sound was but it woke up my baby and was definitely at least a few houses away.
