ditty, i surrender. don't shoot, i surrender. >> reporter: and following that moment, the crowd in the auditorium gave him a standing ovation. so the question now, what's next? no word yet on where

commissioners acknowledged the puc must rebuild its representation. janelle? >> thanks, tony. here is a look at the timeline of events leading up to peevy's departure. he was appointed president of

and pg&e. a few days later, peevey announced he would not seek reappointment. while today was his last meeting, december 31st is technically his last day. you can watch all of tony's investigative

activity with some blue skies earlier today. returning to the bay area. but now it's dark again, and the change is en route. nbc bay area's chief meteorologist jeff ranieri is tracking the timeline of what is now a fourth storm of the week. jeff? >> i know. hard to believe here that we've seen that many storms in just a seven-day period. you see the satellite radar picture has this long stream of moisture that is going to be trailing in here as we head through the next 24 hours. tonight i really think there is not going to be a whole lot of activity. through 8:30 you're pretty much in the clear here. we'll have most of the heaviest rainfall to the north. by 11:30, we'll likely see areas of showers, possibly down to san francisco. and then by tomorrow morning, that heavier rainfall begins to develop first off in the north bay. we'll good ahead and take you into the timeline. and once again, some scattered showers tonight through tomorrow morning. not only the wet weather, but also some wind, 15 to about 25 miles per hour. that could take down more trees, cause us more power outage issues, and about a quarter to half inch of rainfall may even produce some isolated flooding. here is a word of warning. if you had any indication at all that you wanted to head out on your boat tomorrow you want to change those plans. wind-whipped waves already at 9 feet. well likely could see them 15 to 17 feet for tomorrow. we'll talk more about this storm system and sierra snow in about 15 minutes. >> okay. thank you so much, jeff. well we have this brief break in between storms caltrans has been busy trying to fix the problems created by the rain. today much of the focus was on thousands of newly created potholes that are damaging cars. nbc bay area's christie smith is live in berkeley along i-80 one of the biggest trouble spots in the bay area. christie? >> reporter: i noticed some of the potholes on the way into work today. caltrans says pot moles tend to occur during the rainy season. with all the rain we've had, they have crews busy trying to fix them. a day without heavy rain didn't exactly mean it was smooth sailing for drivers. >> it's pretty bad. very rough. i got to hold on to the wheel super tight. >> reporter: he takes interstate 80 in the east bay and says he has noticed potholes including some created by the storm. >> there are some pretty bad one, especially coming through richmond and pinole. only because i drive it every day, i keep an eye out. >> reporter: today caltrans crews were busy making temporary fixes. >> well, the rain always makes the potholes worse, because what happens is the tires on a car or truck actually squeeze the water into the asphalt, into the pavement. so that's what cause as lot of the potholes that you see out there. >> reporter: another possible factor how close the vote to potential floodwaters. martin has a tire shop in berkeley. he says business is up. >> i've seen a lot of flat tires, a lot of damaged tires, a lot of blowouts and stuff. >> reporter: they showed us the damage potholes can do. caltrans says there is a process if your car does get damaged. >> they can file a claim. just go to our website. we go through the process there, as i'll explain. >> reporter: caltrans is also reminding drivers not to litter saying it can clog storm drains and lead to standing water which can create more potholes. and they say if you want to report a pothole, you can send an e-mail to caltrans. they have information on thou do that on their website. reporting live in berkeley christie smith, nbc

tonight. >> reporter: a lot of backlash, jessica. this is a much smaller protest than what we've seen in san francisco, oakland and berkeley. but the message is still the same. >> no justice, no peace! no racist police! >> reporter: they want increased racial awareness, and a less abusive police force. this group, though including the naacp has a couple of extra demands. mainly they want officer philip white fired. he is the officer who recently posted on social media a couple of controversial comments which these protesters say are inappropriate and illustrate the power that they say some police officers are inappropriately wielding. they began their rally and march at the d.a.'s office a couple of hours ago, asking that they prosecute all law enforcement accused of crimes no discretion. then they made their way over here not too far to sjpd headquarters to hand over a petition with 15,000 online signatures demanding that an officer white be fired over twitter posts, including threaten me or my family and i will use my god-given and law appointed right to kill you. and by the way if anyone feels they can't breathe or their lives matter, i'll be at the movies tonight offduty, carrying my gun. the chief accepted the signatures and vowed to look into the posts. >> i can guarantee you, we are looking at this as we have been proactively and aggressively to bring justice so you know that we will do that because it's important to us in terms of what we represent, which is you. and that we are not above the law. >> reporter: they also want the rest of the police force investigated to see if any other officer feels the same and if so, that they be removed too. now officer white is on paid administrative leave while the agency looks into this matter. and luckily, fortunately, these protesters were peaceful. and as far as i know they have not damaged anything. live in san jose nannette miranda, nbc bay area news. >> thank you nanette. the well-known hands up don't shoot gesture was the focus of the demonstration today at san francisco's hall of justice. the city's public defenders led that rally. they say to show support for racial justice. hands

than four hours that michael brown's body remained on the streets in ferguson. police say his body was not moved because the ferguson pd had to transfer the investigation to county officers and there

boyfriend is checking to see if they can track the stolen ipad. >> this is the find my iphone app. and basically, i'm waiting for that ipad to light up. >> reporter: he says he knows the chances of recovering the items is slim but hoped for the best. >> if family members end up knowing these dirtbags that took these things and have some sort of conscience and don't want that kind of karma coming their way, maybe you can turn them in. >> reporter: marcy says she knows that the ipads are valuable and worth something, but she is more concerned with the personal items that were inside of those two bags. spokespeople at valley fair did not have a whole lot to say about this case specifically, other than they take the safety of their customers very seriously and have increased security over the holidays. live in san francisco, kimberly tere, nbc bay area news. >> let's hope she gets the bag back. thank you. well suspended state senator leland yee has a date for his corruption trial. june

recent rain has made a waste water system overflow. the water is beindrerouted out of the system. park officials say it won't flow into the bay. until the problem is fixed, ferry service has been stopped to angel island. all right. let's get the latest from jeff ranieri. we had a little bit of a respite today. we even had sunshine. but it's about to change again. >> you can see right now we're already beginning to see the clouds moving in across the bay area. most numerous throughout santa rosa, sonoma and napa. more offshore. you can clearly see that next storm system lining up. here is what we have happening. you have the cold front situated about 400 miles out. that's that line back there. that's going to bring us the heaviest rain. ahead of that you have moisture streaming in from the south. a little bit of subtropical moisture. so it looks again as if we'll have a decent round of rain here coming our way as we head throughout friday's forecast. you can see right now it's mainly cloudy and also cold. temperatures in the 50s. you can leave the umbrella at home here for most of tonight. but you'll need that jacket with temperatures in the 50s. let's do it. let's take you here to san francisco. the shot looks so beautiful. you can see right here in downtown, some excellent visibility. but in about three to four hours from now, it's going to be changing, as not only fog arrives, but once again, eventually some rainfall. we'll take you to the forecast for tomorrow. all areas expecting rainfall. and temperatures are going to stay on to the cold side as well. we're not going really warm up whole lot from the current temperature right now, upper 50s to about 60. and rain in the north bay, peninsula and also for the south bay. let's get you to the other concern. that's going to be the wind. 11:00 tonight, 22 miles per hour. as we head into the early morning hours, as the storm begins to arrive we likely could see wind gusts as high as 23 miles per hour in redwood city. maybe as high as 26 in orinda that could be enough to bring us maybe more power outages. not only wet roadways, but very win it di. winter weather advisory up again for the sierra. if you're headed that way for an extended weekend, watch out from 4:00 a.m. to 10:00 p.m. snow across areas. about 3 to 6 inches over the next 24 hours. not major snow but it definitely is going to get a

incorporated into the housing that is already being built. >> and have that as an ongoing legacy for affordable housing in that region. >> reporter: the mayor's promise, no white elephants. at least not permanent ones. the olympic stadium would be recycled. >> we would repurpose the steel or construction projects. >> reporter: the site of the recyclable stadium coincidentally, a landfall along the bay just south of candlestick. the cost of putting on the games an estimated $4.5 billion all from private sources. >> so that would be i received contributions that would be ticket sales. that would be domestic u.s. licensing. >> reporter: but during last year's america's cup, the city did get stuck with a multimillion-dollar bill. venture capitalist steve strandberg told report theirs time

happened at sony should according to cybersecurity experts, be a warning to us all. >> this is the first time i think we've seen it at this scale. >> reporter: the goal of hackers is not just disruption, it's fear. >> this is different. the way they were able to combine this online attack which got them the attention they want and mixed that with the threat of physical violence it's new. this is something we really haven't seen before. >> reporter: but likely something we'll see again as hackers try to invade banks, retailers, anything with an easy to open virtual door. >> i think everyone needs to be worried about this. whether it's an organization whether it's a government entity or whether it's an individual. >> reporter: so what comes next? well, for sony it tries to stem

the breakthrough is raising hope and optimism. the country's economy is in shambles from 50 years of communism and u.s. sanctions. but now the prospect of legal tourism and the jobs it would create has both american companies and cubans on the island excited. there are two huge roadblocks though. first, congress must lift the embargo on tourism and on investment. and second cuba's leaders must agree to let big business in. >> the idea that they're going to turn over control to u.s. companies, and they're going to open things up, i am very skeptical. >> now with republicans in control of

month there's was speculation that complicated repairs would be needed after 30 fasteners snapped. but a new report from the oversight committee says thousands of rods and bolts that had been under scrutiny are secure and should stay in place. the report cautions that the parts will need regular maintenance and anti-cross sieve treatment. i want to take you outside. golden gate bridge a live look. that bridge gearing up for the installation of a movable median barrier. it's been talked about for a decade. but now finally thousands of concrete and steel barrier secs have been delivered. they were delivered this week and they're stacked in a parking lot. once the clock strikes midnight january 10th, the bridge is set to close for 52 hours so crews can install the new median. the sidewalk will be the only way to get across the bridge during that time. fed ex is expecting to make about 290 million deliveries during the holidays but labor negotiations could slow things down. west coast dock laborers have been in discussions since this summer. cargo congestion is building up as the talks slow down. in response fed ex has put a cap on last-minute deliveries. ups is also warning retailers of the backup. one fix would be to ship packages via air delivery which is more expensive, but does have a better chance of making it under the tree on time. >> shoot. >> brief

advances are uncovering some fascinating insights about an overlooked species. >> reporter: if any marine creature has gotten its 15 minutes of fame and then some it's the white shark. no introduction needed there. but if the shark kingdom has a bit player, that would probably be the salmon shark. >> salmon shark is the smaller cousin of the white shark. that's a picture of one jumping. until relatively recently been pretty poorly studied. >> reporter: salmon sharks may be lesser known than their famous cousin but they turn up occasionally munching salmon near alaska on the ends of fishing lines or washed up on beaches. >> they weren't even described as a species until 1947. >> reporter: at the marine station in monterey they're now paying these elusive sharks plenty of aye tension. >> you're trying to to describe what a salmon shark migration pattern, there is a bunch. and we're still trying to wrap our brains around that. >> reporter: to find out where these mysterious travelers go and what they eat, researchers like aaron carlyle are turning to cutting edge science. >> it turns out they lay down their vertebrae, just like trees lay down rings. this is a shark vertebrae. >> reporter: by analyzing the vertebrae of the sharks saifs are getting a dna snapshot of what foods they've eaten which then tells them where they dined. >> if you eat a squid in california that looks different than the same kind of squid in alaska. that's one of the bans. that's what that animal did the first year of life, the second year. >> reporter: the research has revealed that sharks travel from california to japan, spending a good amount of time in alaska baja and the waters of the bay area. >> we've had animals tagged from prince william sound in alaska come swimming offshore. >> reporter: it hasn't been used extensively with marine creatures. >> that's a picture of a tag. >> reporter: but researchers at hopkins are now combining it with traditional electronic tagging. >> what is really becoming cutting edge is using these advanced techniques together to give us much deeper knowledge than we ever could with only one. >> reporter: the new use of dna tracking could soon be used to learn more about the lives of other marine life. >> we're going to try to do a similar thing with white sharks. >> reporter: by learning about the travels of salmon sharks regulators can taylor fishing regulations to better protect them, even though they'll never be quite as famous as those other guys. >> fascinating insight into sharks. let's turn things over to jeff. jeff you're the

the ship's landing here out there towards the docks, looking good tonight. let's take a look at the forecast and get a look at the storm system that is coming our way. we do have concerns for this. just because over the past three weeks, we've had 5 to 15 inches of rainfall. the ground is completely saturated. it really can't take any more water at this point. so we do think as we head throughout 11:30 tonight, no major flood concern there. but some areas of rainfall will continue to develop up into marin, napa, sonoma counties down through likely san francisco. by tomorrow morning, it's mainly about the north bay at 5:00 a.m. for some of the heaviest rainfall. it's going to quickly advance to the south by 7:00 throughout san francisco. also back here for the east bay. and down to about the mid peninsula towards palo alto as well. then as we head throughout 9:00 and tonight:00 moves into san jose. eventually down to morgan hill and gilroy and the santa cruz mountains as well. you can see a little bit of yellow that has been popping up in this as we headed throughout the futurecast at the slight risk of thunderstorms and heavier pockets of rain. the best news of this storm system, it's going to hang around all day long. one income the afternoon, a few spotty showers left. but the bulk of the storm should be heading off towards the south. let's take you to the microclimate forecast as we head throughout friday. everyone expecting rainfall here from the south bay down to san francisco. temperatures you'll also find not a big variation here. san jose expecting 60 degrees across the peninsula. we'll go with 61 in palo alto. a few spots, though will have a better chance of some heavier rainfall where that storm system arrives first. like across the peninsula and pacifica. also for san francisco. let's take you to the north bay, east bay and tri-valley. and the heaviest rain likely be in napa and santa rosa. for everyone else it looks like moderate rainfall. once again with the recent storms, we'll have to watch out for possibly isolated road flooding and maybe minor power outages. next five days it looks great here in san jose. dry weather saturday sunday and monday. right into tuesday of next week. san francisco in the north bay. hang on to a slight chance of shower on saturday. but then you're dry after that. looks dry right
