9:22 PM: Though it’s a rainless night, water is rushing downhill in the Luna Park area under the West Seattle Bridge. We checked it out after a tip from Stephanie. A Seattle Public Utilities worker was checking it out along 30th SW, uphill and west of Avalon Way; he told us an SPU crew would be on the way over after fixing an unrelated break downtown. We have a message out to SPU to find out more, including whether anyone is without water service because of the break.
10:37 PM: Haven’t heard back from SPU, so we might not get any followup info until tomorrow.
1:52 AM: Thanks to commenter SEW for an update – not fixed yet.
