bay. how far traffic is stacking up. we're look at mostly cloudy skies around the bay area this morning. but we are going to see a little sunshine by the afternoon. we will talk about that in just a moment. good morning, everyone. it's monday, january 30. not sure what that was. but it's monday. we're going to try to get that fixed for you. i'm grace lee. frank has the morning off. we begin in oakland where in just a few hours, city hall will be open for business. that's despite a chaotic weekend with the "occupy" demonstrators. vandals broke in, shattered windows and burned an american flag. gil diaz is in oakland to show us the clean-up that needs to be done. >> reporter: good morning. a whopping 400 people were arrested over the weekend. there was a clear statement that the city was fighting back. but yeah, this morning, they have to do a lot of clean-up not only inside city hall but also outside at frank ogawa plaza. graffiti, a lot of it. this is a huge graffiti sign we found on the floor. at the top of the sign it says, peaceful assembly which is ironic because if you ask any official here, they will tell you that the protest was anything but peaceful. for example, they burned the american flag outside city hall on saturday night before breaking into the building. and once they broke in, they practically destroyed almost everything in their path. mayor jean quan showed us the aftermath, broken windows, an architect's model of city hall tipped over and damaged. more graffiti in there as well as debris strewn all over. prior to raiding city hall, a group tried to "occupy" the ymca at 24th and broadway. hundreds of them arrested there on the spot. they claim that the ymca staff invited them in but police said they were breaking in. now, the movement began when demonstrators tried to take over the empty and abandoned kaiser convention center near lake merritt. they began tearing down the fences surrounding it, antagonized the police by throwing rocks, metal pipes, bottles at them. the cops fought back with tear gas, bean bags and smoke bombs. >> it became clear that the on general electrictives of this crowd was not to -- that the objective of this crowd was to repeatedly attempt to illegally occupy buildings and confront police, and it was not peaceful. >> reporter: during the melee, three officers were hurt. one get a cut to the face. the other two got injuries to their hands. now, the cost of damages to the city and to frank ogawa plaza, mayor jean quan estimates it to be about $2 million. if you add the cost of the police force around those buildings and police and demonstrators, that cost goes up to about $5 million. back to you, grace. >> all right. with the very latest, gil diaz in oakland, thank you. police are saying that because of this weekend of action, they were not able to respond to other calls throughout the city. officers received more than 1700 of them for service that they had to delay or skip. more than 480 of those were 911 calls. a peeping tom has been harassing women at stanford. campus police say the suspect has struck four times this month on the first floor shower room in cr you. theres hall. also week a woman was telling people that someone was trying to take a picture of her while she was taking a shower. when the victim realized what was happening, of the peeper left. anyone with information is asked to call police. there is a status conference today regarding the domestic violence case against san francisco's sheriff. ross mirkarimi pleaded not guilty to the misdemeanor charges this month. he is not required to attend today's conference. it's basically for the attorneys on both sides to update the judge on how the case is proceeding. facebook is on the verge of making history. the social website is getting ready for its much-anticipated wall street debut. lisa washington is at the facebook headquarters in menlo park and this could be one of biggest ipos ever. lisa. >> reporter: with its initial public offering, facebook could take in more than $10 billion. this would be the largest ever ipo for a u.s. internet company. this would put facebook in the lead of companies like mcdonald's and amazon.com. there are more than 800 million users of the social networking site. and facebook has some 3,000 employees. the sec filing could come as early as wednesday and the company as we said could raise as much as $10 billion. that would put the value of facebook at between $75 billion and $100 billion though some analysts wonder if the company is really worth that much. because facebook is a private company, very little is known about its actual revenue and profits. filing with the sec could change that. >> i think they are going to learn about salaries how much people maybe how much is mark zuckerberg and the chief operating officer, what are their salaries? how are the relationships between the companies that do business with facebook? who do you people get paid? how would a company get paid? >> reporter: many people compare facebook with its main rival google. there are two differences that we should point out. google had its ipo six years after it was founded. facebook would be eight years after it was founded in 2004 by mark zuckerberg, if they file. they both make their money from advertising but there are reports that google makes far more in ads than does facebook. but we could get a lot of answers and find out just how many dollars the company has if they make that filing with the sec this week. >> it will be interesting to see how much they make. there will be much more on it coming up on "cbs this morning" at 7 a.m. it appears mitt romney may regain momentum with the presidential primary in florida. he has a substantial lead over his fellow republicans in the sunshine state, according to polls. the top vote getter will receive all of florida's 50 delegates. newt gingrich is running in second in florida. he continues to campaign there. we'll have a live report from tampa coming up in a few minutes from now. we have two separate accidents in san jose that you might want to watch out for. elizabeth?

reporter: it's been a fierce past few days for the florida campaign. negative ads flying back and forth. romney is outspending grim by a factor of 5 to 1 and that's what's being pinned as the reason that gingrich so far as at least conventional wisdom says he is about to get clobbered here tomorrow. >> reporter: mitt romney is trying to pump up florida voters ahead of tuesday' critical primary. >> get out and vote! vote on tuesday! >> reporter: at a packed rally in pompano beach last night, he kept up his attacks on rival newt gingrich. >> his record was one of failed leadership. we don't need someone who can speak well perhaps or who can say the things we agree with but does not have the experience of being an effective leader. >> reporter: romney leads the gop pack in florida but gingrich insists the race is actually closer than polls show. the former house speaker greeted voters sunday and said he is willing to keep up his fight well past tuesday. >> the clearer we are about a pro-abortion, pro-gun control, pro-tax increase massachusetts moderate, the less likely it is that he is going to win a majority anywhere. >> reporter: as gingrich and romney battle it out for first place here in floridaings the other contenders are already looking ahead to the next big contest. rick santorum is expected to campaign in missouri and minnesota today. the former pennsylvania senator

but thank you all for coming out. it's just so encouraging to see all of you here. >> reporter: as for texas congressman ron paul, he's bypassing florida altogether, focusing instead on caucus states like nevada. and there is a new poll out that's talking about a potential -- it was a poll of 12 swing states plus nationally, it says that in a contest between president obama and mitt romney, voters are split and in a contest between president obama and newt gingrich, they prefer the president. >> susan, it seems that newt gingrich is saying he is a legitimate heir to president reagan? what kind of reaction is that getting in florida,. >> reporter: it is getting reaction. there is an ad run from romney showing somehow gingrich exaggerates his ties to president reagan and so gingrich came out and said that today he is going to be campaigning throughout florida with the son of president reagan, michael reagan. that's going to prove, he says, that he is the heir to the reagan movement, he says. >> we'll see what happens next. susan mcginnis live for us down in florida, thank you. the main website for the city of sacramento remains down today. the site was apparently hacked during the weekend. two other sites run by the city were taken down just as a precaution. the city says no personal data was compromised. and it is still working to get those sites up and running again. all right. getting busy on the traffic front. elizabeth? >> we are following a couple of different accidents in the south bay one on 101 and julian is now gone but we're still following this one southbound 880 at brokaw road where at last check they have two lanes blocked off. it was an overturned injury crash and they updated us about 15 minutes ago hoping to reopen lanes shortly right around now. but so far, we are still seeing backups. looks like it's slowing into milpitas in those southbound lanes so again we'll let you know when that accident clears. the rest of the south bay now actually looks okay including one more live look at 280 traffic out of downtown san jose. so there was some earlier police activity on a capitol corridor line train 518. so right now there were reseddual delays from richmond to martinez. all other mass transit including bart, ace, muni, caltrain, your ferry, everything else is on time. so at the bay bridge, still no metering lights at the bay bridge toll plaza so some slight delays in some cash lanes. and you can see across the deck, this is actually on the san francisco side of the span, so far everything looks great and lower deck traffic is fine. they did pick up some earlier roadwork about 15 or 20 minutes ago. that is your traffic. one more look at your forecast, your monday morning back-to- work forecast. >> it was a fantastic weekend weather-wise but seeing clouds until the skies now mostly cloudy, as a weak cold front slides through. we have some cloudy conditions and some fog toward the beaches. overcast though inside the bay with mid- to high-level clouds the same with the valleys and temperatures mild in the 40s and 50s. this afternoon that cold front will swing by leaving mostly sunny skies inside the bay. it will be sunny skies in many. entire yor valleys but cooler temperatures highs in the 50s to mid-60s in the warmest spots so we just cannot get the rain going this season. we had one outbreak of good rainfall but now dry weather will stick around for some time. that rain staying to the north again and no there of rain in the near future. looks like -- no threat of rain in the near future. looks like high pressure builds in, in the middle of the week. front moves by today, patchy fog developing along the coast, some of that surging back onshore overnight tonight and into tomorrow morning. so gray start to the day for tomorrow. so we'll keep those temperatures down over the next few days. high today plan about 64 in morgan hill, 60 in san mateo. east bay 63 in livermore, 62 vallejo. inside the bay temperatures up into the 60s in oakland probably low 60s into san francisco, 50s at the coastline. next few days going to keep those temperatures down but by thursday, high pressure really begins to build in. those offshore winds kicking in will warm your temperatures up as we head toward thursday, friday and next weekend looks like we're going to stay dry for the next five to seven days. >> hard to get back to work today. >> it is. >> it was beautiful. >> surprised you're here. >> exactly. 6:22. the road to oscar gold. the big win for women at the screen actors
