12:18 PM: Seattle Public Utilities tells WSB that a six-inch water main has broken on Prescott Avenue SW in northeast Admiral [map], and repairs will require shutting the water off for at least four hours. SPU’s Cornell Amaya says about 45 services (households, etc.) will be affected, on Prescott SW and Prescott Place. If you’re in that area, you might already be experiencing lower pressure and/or discolored water. He adds that the water mains in that area are “pretty old, and sometimes they just break.”

1:43 PM: Update from SPU – the crews worked so fast, the water’s already back on.
