Thank you, leyla. Now back to breaking news we first told you about on twitter overnight. A water main break has flooded half a dozen San Francisco homes. Abc 7 News ReporterTiffany Wilson joins us live from the bay view district. Hows it looking right now, tiffany . Reporter well, matt, the situation is improving, but crews still have a long way to go. If you look over my shoulder, up the hill to where theres a truck parked up there, thats the focus right now. Its very close to where the pipe broke. Two pumps are working to evacuate the water in the sink hole that was created by the water main break. Once theyre able to access the pipe, they will start doing repairs. The Public UtilitiesCommission Says it was a 12inch water main installed in 1953 that ruptured around midnight. Water gushed down keith street and flooded the basements and garages of half a dozen homes. Family members tried to make impromptu barriers with pieces of wood. The Fire Department also created a barrier of sand and asphalt to help redirect the water into strorm drains. The cleanup and repair process is expected to take hours. So were going to open up the pavement, expose the pipeline that broke, and take a look and see what type of fix is needed. We are estimating about three blocks that will be without Water Service while were doing the repairs. We also have crews coming out to assist the homeowners that did have damage to help clean out their homes. They should be out here within the next hour or two. Never seen nothing quite like it before. Its interesting. I dont even know what it is. Pipe must have broke or something. Nerve seen nothing quite like it in my life. Reporter it certainly was an unexpected and unwelcome surprise for residents in this area. The video youre looking at right now shows a car that was parked directly over the water main break. A sink hole started to form around it. So crews had to call in a tow truck to remove that car. If you come back out live to the scene here, you can see water is still flowing right around that car. Fortunately, the flow has been slowed down enough that the water is going directly into the drain. However, if you have to drive through the bay view area, beware. A lot of the streets around keith and key have been closed down, so you may have to detour this morning. In San Francisco, Tiffany Wilson, abc 7 news. Tiffany, thank you.
