Steph, you were on that train this morning. It seemed smooth, so whats next. Reporter yeah, that is the big question, scott and kris. Were at the fremont stop and this is that stretch where the derailment happened monday night. Commuters should expect delays tonight as they go home because trains are going slower for safety, but one question has been will Union Pacific install any sort of land or mudslide detectors after this. Right now the answer is not likely. After one day offline, ace trains are back in service. We boarded train number one, the first in the morning to check in with regular riders who echoed the same feelings. I can understand how that happened. Accidents happen once in a while. Reporter conductors are slowing the speed to 10 miles an hour through the stretch, the 40mileperhour zone, where track inspectors are monitoring activity. Longtime passenger fred barnes rides almost daily. Hes hoping theres added attention to the area where the mudslide derail edmonds train. Ive got through there at 4 00 in the morning going to work and there have been rocks on the street from rock slides. Reporter Union Pacific owns the tracks and is leading the investigation. Spokesman Francisco Castillo said a weather team sent track inspectors to check that very stretch around 5 00 monday morning. Everything looked fine. Union pacific is looking at the possibility of installing slide detector fences, but will probably pass because, castillo says, there hasnt been a landslide there in at least 20 years. I think they keep it pretty clear most of the time. Ive been riding about a year and havent had any other issues like that before. I think theyre going to take a sharper look at it because its going to need to be addressed, even though weve been in a drought for years now. We get a couple big rainstorms like this and things are going to move. Reporter i also understand and learned this morning that Union Pacific has a geotechnical Consulting Engineer on site thats still on site to help determine how that mudslide led to the derailment and the best path forward. No timeline on whats going to come out of what he has to say. City perhaps no one will enjoy that break from the rain more than those folks. But we do have more wet stuff headed our way. Our live satellite radar shows a strengthening storm thats coming up off the coastline. Looking live at the Golden Gate Bridge, you can see clouds hanging around. Meteorologist rob mayeda joins us now. Rob, series of storms headed our way. It sounds like were a broken record here. And we may be breaking records for rainfall as we head towards friday and the weekend. Right now really a clash of two different weather patterns. San jose in the mid60s and may get close to 70s in parts of the south bay. Different stories you just saw. Across the Golden Gate Bridge youve got your drizzle storm under way, 59 degrees and rain continues to fall mostly in the north bay. As you head through the afternoon youll see light rain lift on off to the north bay as High Pressure temporarily builds in but you can see all this moisture offshore. The pattern that is setting up as we get into thursday, we saw it this past weekend where that atmosphere and river connecticut back to hawaii connects to the bay area. Well see strong winds and the potential for very heavy rain, especially thursday and friday. For the north bay localized flooding is an issue and sierra snow 2 to 3 feet. All this rain coming down is now starting to cause the larger rivers to react. Here is the forecast stage for guerneville as we approach the weekend. Very close to flood stage, which is 32 feet. Now that the ground is saturated and the river is off to a higher start as more rain comes in, you can still be watching these very closely for thursday into friday in the north bay and into the weekend. Well let you know how much longer this rainy pattern will stick around and how much rain you can expect in your neighborhood coming up in a few minutes. A tree fell on four cars near San Francisco community college. You can see the damage there. Crews working on cleaning that up. Nobody hurt. No word on what caused that tree to come down but as we all know weather is most likely the factor. Stay ahead of the storms with our nbc bay area app. Its a great resource to know when the rain is going to hit. I use it right around pickup time at school. Its free to iphones and Android Devices. It has happened again, raw sewage going back into peoples homes on the peninsula. This started saturday because of recent rains. Crews on the scene are trying to work on a solution. This is in millbrae. Bob redell is live in the neighborhood. Bob, are people out of their homes this afternoon . Reporter kris and scott, we know of at least two families who have moved into hotels, including the chens who live in this home right here behind me. It was their home that flooded again with raw sewage overnight because of a clogged sewer line. You can see right now the city is trying to fix. How. Hell can we flood twice . I was like i think i think i dont think it can get any worse. Reporter thats a very frustrated jason chen showing us the cleanup a restoration had to do in his house for a second time this week after feces and other debris started pouring from his toilet overnight. He and at least one other homeowner are point their fingers at a Company Called sewer rat for this problem. That contractor has been replacing a sewer pipe connection for one of chens neighbors. The city suspects during this job workers for that Company Allegedly left part of the sewer line improperly sealed. This weekends rains were able to push base rocks into the sewer main. As a result, the main clogged, forcing raw sewage to back up into several homes for several hours on saturday. Im very upset, but what i cant do anything now. Just deal with it, fix it and then deal with it later. Reporter who do you blame . Well, i think sewer rat sewer rat is all to blame. Obviously the drain route is not supposed to be in the sewer line. This has been happening for almost five days and its very emotional and nobody is helping us and i dont have a lawyer right now. Im trying to find someone really good. Thats it. Reporter that was jasons neighbor, who allowed us to accompany a Restoration Company into his home this morning. He believes his house of eight years is going to need to be torn down after the flooding this weekend but he tells us his Insurance Company is refusing to pay, hence the reason hes looking for a lawyer. We did speak with the interim public works head of the Public Works Department here in millbrae this morning. He sympathizes with these homeowners. Hes asking them to file a claim to the city. We also reached out to sewer rat, but so far no comment from that contractor. Again, back out here live, you can see the city has hired a crew to replace those sewer lines because its so hard to dislodge the rocks, so replacing the lines is so far their only option. Reporting live here in millbrae, bob redell, nbc bay area news. Bob, thank you. A developing story, a quiet seattle, washington, neighborhood was rocked overnight by a massive explosion.
