Businesses dont want to give customers the wrong impression. I just found out a couple minutes ago that this Neiman Marcus in walnut creek will be closing early tomorrow, at 5 00 p.

A firefighter is in Critical Condition after getting hurt while battling a fire there in the city. Nbc bay areas jean elle is in the financial district with details. Jean, what do we know . Reporter this is a very emotional scene and investigation unfolding right now here on speer street just off market. Let me get out of the way, and you can see there are several firefighters standing in the street, and there is crime tape surrounding a fire rig and a muni bus. The Fire Department says a fire crew was here at 3 30 at 55 speer responding to a high rise fire on the it 19th floor. So there was a lot of activity here on the ground and up in the building itself. And while that was happening, a muni bus drove through the area, and as that muni bus drove through the area, im told a very large hose snapped up into the air and hit a firefighter, launching him into the air. When he landed, he was injured. He had a head injury and possibly other injuries. Im told he was unconscious and not breathing here at the scene but was taken to General Hospital where im told now he has critical injuries but is still alive. But he is critically injured. Were told he has lifethreatening injuries. So right now the San FranciscoPolice Department is here investigating what exactly happened. Its not exactly clear what happened. All were being told is that a muni bus drove through the scene here as firefighters were busy fighting this fire, and when that bus drove through, a hose moved quickly and injured that firefighter. His name is matt vaughn. He is a sixyear veteran of the department. Reporting live in San Francisco, jean elle, nbc bay area news. Thank you, jean, and our thoughts, of course, are with that firefighters family. Back to class. The San Jose Unified School district announced it is ready to open up school campuses. The district says its possible because Santa Clara County is now in the orange tier for risk. We are told what has to happen to make this happen long term. Reporter its been a quiet campus here for a long time, and district people we talked to says limited reopening is a logical next step. They also understand how quickly they might have to step back. Many instructors in the San Jose Unified School district have been teaching from empty classrooms with its 28,000 students following online from home. Today the district announced it will offer inperson instruction as an option starting january 5th next year. Most families we talked to expressed excitement at the chance but acknowledged some concerns. My biggest scary feeling is how are they going to make sure that the kids are practicing not only distance, but also when its time to wipe the desks down or go to the locker or to the restroom or things like that. Reporter the district says it is developing training for students and staff and updating its already rigorous safety measures. I mean, i worry with the cold weather coming up and flu season and everything else, but if were able to maintain this and stay in orange or yellow, its very logical to say to our families, if you want inperson, we should be able to provide it for you. Reporter wheatley also emphasizes any covid spike and the plan will be paused. Well just have to wait and see, but eventually we all have to go back. I just wish there was a vaccine out right now. Reporter the district is in the midst of talking to parents right now to explain options. The final decision will be made on december 30th, the last day the county gets its tier rating before School Resumes after the holiday break. Robert handa, nbc bay area news. Lets get back to our election coverage. The ballot box might be leading to the courtroom, in fact, it already has. Even before tomorrow, judges and lawyers are a very big part of this election. The latest battle coming out of texas. Lets go to janelle wang who joins us with the details. Janelle . Raj, because of the pandemic, states have adopted different ways to make sure people feel safe voting. For example, here in california, officials sent every registered voter in california a mailin ballot whether they requested one or not. In Harris County, texas, which includes the city of houston, Election Officials came up with drivethru voting. About 127,000 people have voted that way. A group of republicans filed a lawsuit saying its unconstitutional to vote like that, and those ballots in a very heavily democratic area should be thrown out. But both the conservative Texas Supreme Court and a federal judge said those votes will be counted. The u. S. Supreme court has also seen similar cases in recent weeks, and it appears the courts are consistently giving deference to the state. One principle thats come into play in a lot of these cases is this idea that has been around for a couple decades now that the courts should stay out of reshaping elections as the time for the election gets closer and closer. So that may be part of the reason why the texas court today, even though it decided other grounds, decided not to cast out the ballots from drivethru voting, because it would have required Harris County to call up 120,000 people and try to get them back to the polls tomorrow. Reporter does this surprise you with all the lawsuits and cases going to the courts a day before election day . Its not that surprising, because in general this election is hotly contested, and the Trump Administration has made clear that theyre planning to bring lots and lots of lawsuits. There was an article about how they have a lot of complaints already filled out in the event that the election doesnt clearly go in their way. So i can imagine that we will see a lot of cases coming up in the next few days as well as today and tomorrow. Newest Supreme CourtJustice Amy Coney barrett has not participated in this week. We believe it is to tamp down issues because she was passed through confirmation so quickly. But expect her to be back in the coming days. Thank you, janelle. Up next, what are they doing to stop misinformation on Election Night . Facebook and twitter laying out their plans. But a social media expert says theres Something Else we can all do tomorrow night. Plus, voting in the time of covid. What you need to know before heading to your polling place tomorrow. And im chief meteorologist jeff ranieri. Ill show you the clouds moving in for tomorrow.

So whats the plan tomorrow for twitter and facebook . And what if President Trump tweets that hes the winner of this election even if thats not true . Today an update from our local social Media Companies as they fight false information. Heres business and tech reporter scott budman. Reporter its down to the wire for the president ial campaigns and their social media feeds, which is significant because millions of people now use social media to get their political news. A lot of people get it from social media. Thats all i see. Reporter even knowing a lot of it is flat out wrong. Anything you hear, you sit there and youre like, huh . Reporter the Company Admits theyre fighting election day information. Twitter says theyll rule out false claims as well as bots that spread lies. It will also wait for confirmation from at least two respected news outlets before declaring a winner. Facebook says it has a virtual war room where employees will fight efforts to destabilize the election and will also wait to declare a winner. Not everyone is convinced its enough. Despite their best efforts, social Media Companies cannot protect us from misinformation. Reporter and we know it. There are so many different followers and people who are able to kind of manipulate that information. Reporter experts say dont believe it just because its posted. It is incumbent upon us as consumers of information to get our news from sources that we can trust, that have a verified factchecking process, an editorial process. Reporter as far as what happens after the ballots are counted and we eventually have a winner, Facebook Says it will suspend all political ads from its site and instagram. Twitter says its ban on political ads will remain in place. In san yojose, scott budman, nb bay area news. Thank you, scott. The virus, of course, is weighing heavy this election. Poll workers in San Francisco have a lot of extra things set up to do this year. The city is making sure each of its 588 polling places is stocked up with everything people need so they can vote safely tomorrow. Nbc bay areas jackie ward breaks it down for us downtown at the plaza. Voting means more to us than all these pandemic measures theyre taking. Reporter from a voters perspective, election day will be a smooth process. Hand sanitizer and face shields have been dropped off at the voting places. We dont want the workers to have to think of what to do on that date. Reporter this die gragram ho set up booths. They got to see the prep when they showed up to vote in person today in the outdoor Voting Center set up next to city plaza. I felt like they did a good job organizing it to make sure people were safe. They didnt let people cluster in areas. I never felt like i was being crowded by or had a risk that i didnt want to be in. Reporter masks are required. If you show up to vote without a mask, youll be offered a free one. If you refuse to wear it, poll workers have been instructed to set up an individual voting booth outside at least nine feet away from other people.

The weather should not be a problem, right, jeff . Thats exactly right, raj. We have some beautiful weather coming our way. A few changes as we head into the morning hours, but all in all, i think we have a nice fall day coming in for election day. Lets get you outside of my satellite and radar picture, and youll be able to see across the west were beginning to see the pattern starting to shift. Its beginning to change in the opposite direction of where weve been with those really hot, early fall temperatures. Youll see there is quite a bit of cloud cover out here in the pacific, and were going to start to see some of that cloud cover beginning to move our way tomorrow. Now, theres no rainfall in the forecast for tomorrow or really for the next few days, but eventually were going to get some of those changes in here. Lets focus right in on those clouds as you move through the morning hours, and i really wanted to show you this, because those cloud covers will be a lot more widespread than weve seen lately. You can see them in the north bay, south bay and also the peninsula. Then as we roll through the afternoon, we will get that sunshine back once we hit about 1 00, and thats really what we set in that nice stride for tomorrow. The other thing i want you to be aware of is the morning temperatures. Its going to be cold to start, and we know there are still a lot of folks that may drop off their ballots late, is to there could be some lines. So if youre up early to get that ballot in the box, get your vote in, it will be chilly, so make sure to maybe take a light jacket here. 48 for the south bay, trivalley at 47, peninsula 49. Right over the east bay, San Francisco and the north bay will be in those upper 40s to late 50s. Cold to start, and as you move through the afternoon with that increasing sunshine, i think the temperatures look all good.
