2:14 PM: Thanks to Dave for the tip – we confirmed with the Seattle Public Utilities crew on the southeast corner of California and Edmunds that they’re fixing a water break. Some traffic effects at that 5-way intersection as a result.

3:54 PM: Elaine Yeung of SPU replied to our inquiry seeking more info, saying the break was “caused by a tree root. Crews have now finished working on the pipe, placed temporary paving, and opened the street back to traffic.”
