merge over toward 680. we have the build coming out of pleasanton. i was concerned about that. it doesn't look like the crash affects your tri-valley commute. a slower drive as well. water main repair work, university is open with limited access. we'll talk more about what's going on in just a couple minutes. >> mike, thank you very much. new this morning, police right now are searching for clues on san jose's sysco campus after a thief or chooefs ditched a stolen sausage truck there. a rep says someone drove that truck through a fence and off the plant's lot in sunnyvale. police briefly chased the truck but lost it in san jose. it woended up at the sysco facility where the driver knocked over several light and fire poles. police in fremont say they need the community's help to

catch the people or person responsible for setting multiple fires. people there, bob, living on the edge. >> reporter: good morning, laura. for police and the fire department trying to find this person, what makes it difficult is they do not have a suspect description. warm springs boulevard is right behind me from hackemore lane on the north down to mayton way on the south of warm springs boulevard. every time it's been a bush, tree or garbage. no homes or businesses. the first fire was set mid july, the 15th fire this past weekend. fremont police say almost all the fires have been set on weekends from saturday evening into sunday morning, and between sunday evening into monday morning. ten of the fires have been set between the hours of midnight and 5:00 a.m. >> that was scary because i was

driving and i saw the trees -- burnt trees. it's amazing. we live in a good neighborhood. we don't expect anything like that. >> reporter: investigators still don't know what's motivating this person as to what would compel them to set all these fires. live in fremont, bob redell, "today in the bay." when you get to school this morning, parents and students will notice more security in the oakland and fairfield school districts. all this is because of threats made on social media by clowns. police say the twitter account called clown gang one made threats against several campuses. the oakland unified school district is investigating the threats posted on social media. students at two different schools warned administrators about those posts yesterday. >> we deployed our resources, vetted out the threat. we called fbi, joint terrorism task force. we take the threats seriously. >> clearly. police are not saying which two

schools specifically are mentioned. the fairfield school district also received threats naming four schools. police say while the threats are not credible, they are taking them seriously. this is happening across the country. ten states are reporting similar threats. >> a developing story we're watching closely as hurricane matthew churns in the atlantic taking aim at the bahamas. the powerful storm has already proven deadly. there's concern this morning it could hit the u.s. right now people from florida to the carolinas are wiping out store shelves as they begin storing water, flashlights and batteries. those living in the storm's path are being told to move at least 100 miles inland. matthew has pounded cuba and haiti with 140-mile-per-hour winds. we'll have much more on the storm's path and the potential impact to the u.s. adds we check

>> consumer investigator chris chmura is here to explain. courtney troy bought a used 2007 escalade this past may. she said the dashboard flickered with warnings about her tires and suspension system. over the next several weeks she took the escalade in to south county chrysler asking the dealer to fix the problem. she said she couldn't get a clear answer from the dealer about what was wrong. she said the problems persisted. courtney reached out to us and we called south county chrysler. it took back the escalade and gave courtney a check for $4,000, her down payment, plus loan payments she made. it paid off her loan, a total savings of $24,000. when we asked south county chrysler it said courtney's resolution had nothing to do with nbc bay area responds. here is something courtney and all car buyers can consider. california law allows used car buyers to purchase a contract cancellation option. this gives the buyer two days to

reuters reporter joe mann who specializes in covering security issues. he writes, it's likely the fbi or nsa approached other internet companies with the same demand, but microsoft and google said, if that happened, they would refu refuse. yahoo! said in a written statement, yahoo! is a law abiding company which complies with all the laws of the united states which really doesn't address the question. this isn't the first time yahoo! has been skapt liesed by an e-mail problem. back in the fall of 2007 yahoo! founder jerry yang was criticized by the u.s. congress after the company turned over user e-mails to the chinese government, and some dissidents were arrested. here is late congressman tom landis. >> this behavior was inexcusebly negligent behavior at best or deliberately deceptive behavior at worst. >> we will continue to cover

this story. the next big question is verizon, which is whying yahoo! did they know about it? >> there were yahoo! employees who actually quit. >> including the director of security. by security i mean hacker security, not flashlight security. he went to facebook. i said is this true why you quit? he said he couldn't comment. >> a lot to take in there, a lot to take in for fans in a good way. a live look at the home of the warriors. by the way, the future is now. the wait to see the newest acquisition was well worth it last night. this was the first chance forwafor warriors to see in person the star-studded lineup that features k.d. kevin durant delivered, scoring 21 points to help lead the dubs to a 45-point drubbing of the clippers. it's only the preseason. so what. friends wanting to see this,

thursday evening and friday curving up towards the carolinas. here is the big forecasting challenge. right now it doesn't look like the northeast is going to see much from the first run of the storm. now the commuter models are trying to loop that hurricane back down towards the bahamas. stay tuned. could be dealing with that storm for a while. now, this morning, calm views around the bay area. bay bridge looking nice, 54 degrees currently? san francisco. clear skies in san jose at 52 degrees. we will see mostly sunny skies today. patchy low clouds moving down the coastline. rebounding into the 70s this afternoon. upper 60s for san francisco. peninsula temperatures in the low 70s and mid 70s around the north bay today and a few upper 70s returning to the forecast around walnut creek and antioch for today. check out san francisco, as we head through the fleet week weekend, gorgeous weather. we'll see numbers approaching 80 on saturday. that means our valley locations,

especially the tri-valley and south bay have a good chance of getting close to 90 degrees. downtown san jose could see upper 80s by saturday. things cool down as the sea breeze returns late on sunday. >> downtown san jose has air conditioning as well, to many of the activities over here. the south bay we see the slower drive, looks like speeds are starting to recover northbound 101 at tremble, where the crash was reporting, we see speeds starting to improve at the scene. the merge off 87, as the traffic by the airport and the build off 101 at 680. typical pattern for the south bay, a little more slowing at san jose airport than you'd expect. crash at stephenson looks like it's not a problem, 880 toward the dumbarton bridge out of the south bay. southbound heading through fremont for the nimitz and into flee montefiore 680 both move smoothly. the earlier crash out of livermore and pleasanton not causing problems there. over towards the bay bridge, a smooth flow on our speed

sensors. the bay bridge toll plaza, of course the backup is there because the metering lights are on. the peninsula, palo alto showing an easy drive, starting to build off the san mateo bridge for the bayshore. up next, hoping to draw on that magic. the giants in new york for a win-or-go-home match-up against the mets. a premier of the aces from the big apple. apple.

the giants - arin nework for a one-game wild card playoff these teams may be full of nice plans, but it's about to a mean showdown. >> the giants are in new york for a one-game wildcard play-off against the mets. the winner moves on to postseason. the losers clean out their lockers. >> colin resch has a preview. >> they've done it before. two years ago, in fact. the giants went to pittsburgh, won the wildcard game and won their third world series in five years. the giants hoping history repeats itself this time around. it starts here in the big apple. a late afternoon workout at citi field tuesday for the guys, marquis pitching match-up expected later tonight. madison bumgarner versus noah syndergaard. bumgarner with a 4-0 lifetime record at citi field. why so much success here? >> i don't know, man. i think it's worked out that way for whatever reason.

certainly glad it has. i don't think there's any good reason for it. >> i love it. i have to. we have a ring because of this wildcard and have a chance now. >> we have to find a way to score more runs than they do. >> reporter: of course, he's right. 1-0 or 10-9, it doesn't map. bumbarner has prove and the giants have proven themselves on the biggest stage over and over again. can they do it again? we'll find out tonight. in flushing, new york, colin resch, nbc bay area. 6:26 right now. >> across the city, students and parents are taking part in an event called walk and roll. supervisors from each district are joining in on the walk. the event is part of the city's new vision zero pedestrian safety expert. there's a superman backpack, billed as the champion for safe

streets, even wearing a crosswalk cape. so look out. >> at '6:27, coming up next on "today in the bay," stay out of the water. two more bay area lakes now off limits to swimmers. >> reporter: pete suratos in the east bay where the nationwide school threats are hitting home in the bay area. i'll tell you what schools are doing about it coming up. you may not have been expecting it, but last night's debate was pretty contentious between the vice presidential nominees. i'm tracie potts. we have a recap and reaction next. joining us on this wednesday.

i'm ura garcia caon. =sam/4shot= and i'm sam (toss rob) good morning and thanes, for joining us on this wednesday morning. i'm laura garcia-cannon. >> i'm am brock. a splash of orange on your tv screen. >> and blue. >> we're rooting on the team in the wildcard game tonight. >> blue is for fleet week? >> for all our teams. >> all giants. >> go giants. >> i can't held it, i grew up in new york. i will root for the giants if they win tonight. i promise. >> you'll wear an orange tie tomorrow. >> yes. >> you heard it here. >> blue and orange across our skies around the bay area.

we'll show you the view outside around san jose. clear skies right now. numbers in the 40s, chilly start, south bay microclimates down to 46 degrees, los gatos at about 48 right now. as we go through the morning, you'll want a jacket through the morning. as we head through the afternoon, pleasant temperatures, 90s as we approach the weekend. now to see what's happening with your bay bridge commute, here is mike. >> we have, of course, your typical patterns around the bay. one more spot to watch for the south bay. first northbound 101 at tremble where chp has arrived. that distraction with flashing lights and the crash at trimble adding to the distraction. more slowing for that section of san jose. the bay bridge we have the backup. the metering lights are on. the beautiful sunrise. also looking at the lights right here. they're backed up past west grand avenue. nothing past the approach. this is quite unusual.

clowns threatening bay area students. two school districts are beefing up security. >> pete suratos is live in oakland. this is a troubling trend across the country and now in our own back yard. >> reporter: good morning, laura and sam. indeed we have seen this around the country. and in response to this, the oakland unified school district is increasing patrols at two of the skoochlts they have not named those schools yet. the social media posts with these creepy clowns was first brought to their attention by two students in the district at those two schools. they're not the only district dealing with this. they're also dealing with it at the fairfield school district. the twitter account is clown gang one. the account has been deleted. that account made threats to a few schools including grange middle school and fairfield high. it's important to note that nothing came of it. we're seeing a lot of these cases around the country, in fact, police are saying locally

these threats aren't credible. but they're not taking it lightly. and the students aren't taking it lightly ever. >> i don't want some crazy guy walking into my classroom and staurt doing god knows what. >> we deployed our resources, we vetted the threat, we called fbi, joint terrorism task force, we take the threats seriously. >> reporter: we've seen these clown threats in a number of cities on social media including philadelphia, new jersey and south carolina. and only in south carolina is there an actually sighting. the twitter account has since been deleting. but these posts qualify as a terror threat under the california penal code which makes it a felony. pete suratos for "today in the bay bay.". >> bracing right now for what could be a dangerous day ahead. there are hurricane warnings in effect, up along florida's atlantic coast as hurricane

matthew continues to churn through the carbene. that deadly storm is set to hit the bahamas. the storm pounded cuba and haiti with up to 140-mile-per-hour winds, washing away roads with fast-moving floodwaters. at least 11 people have died so far. the next stop could be the united states. right now people living from florida to the carolinas are preparing themselves for the worst. >> i've been through three hurricanes before, so yeah want to be caught off guard. >> it gets hectic as soon as the storm gets closer and the cone starts narrowing in. >> highlighting the urgency here, several states have declared a state of emergency as mathew approaches. people in the hurricane warnings from miami all the way up to daytona beach are being told to move at least 100 miles inland. snuffing out an arsonist, 15 fires in the past three months in the same area of the east bay. it's happening in the warm springs neighborhood of fremont. it's been going on since mid july.

police say every time it's been bushes and garbage set on fire. so far no homes hit, but that's what neighbors are afraid of, that this arsonist will change his target. >> there's an online neighborhood watch where we have a group where people are concerned and they mention what we can do to make the neighborhood safe. >> fremont police say almost all the fires have been set late at night on weekends. so far police have motive or suspect. >> a man accused of torturing and killing cats is awaiting his fate. yet robert farmer showed no emotion as he pled guilty to 21 counts of felony animal cruelty. he was arrested last year after surveillance footage showed him trying to round up cats in a san diego neighborhood. farmer is facing up to 16 years in prison. 6:35 right now. nearly 500 fewer officers on san jose streets. that's one of the new numbers

from voter impacted cuts. measure b rolled out four years ago and has been the focus of controversy ever since. over time costs have tripled. officers average about 450 hours in over time every year with some shifts still unfilled. >> you don't see your family. you come to work. you don't know when you're going home. it fatigues your body in a job that can't take that sort of risk of not being at the top of your game. >> measure f will be decided in the november ballot. a break in a string of violent robberies in the east bay. this morning the contra costa district attorney is connecting a group to home invasions in danville, fremont and livermore and potentially to a robbery last week in orinda when two young men attacked a couple in

their driveway, pistol whipping the husband and shooting the wife twice. vice presidential nominees mike pence and tim kaine both in pennsylvania today hours after squaring off in their one and only debate. >> that was interesting and not necessarily what anybody expected. "today in the bay's" tracie potts joining us from washington, d.c. with the political punches thrown from both sides of the aisle. >> reporter: good morning. this morning 48% in the cnn poll say they think mike pence won that debate even though the pollsters talked to more democrats. >> i don't have much of a voice left. >> here is why. >> don't put words in my mouth. >> back and forth for 90 minutes, at times impossible to hear. >> gentlemen, the people at home can't understand either one of you when you speak over each other. >> tim kaine interrupted frequently to bring up donald trump's tax returns. >> why won't he release them. >> we're answering the question about the business thing. >> mike pence on hillary clinton's e-mail.

>> if your son or my son handled classified information the way hillary clinton did they would be court marshalled. >> that's absolutely false and you know that. >> reporter: each accusing the other side of insults. >> you can't have somebody at the top who demeans every group he talks act. >> that's small potatoes compared to hillary clinton calling half of trump supporters a basket of deplorables. >> reporter: pence repeatedly denied trump's comments. >> more nations should get nuclear weapons. >> he never said that. >> they talked about the economy, russia, immigration, police shootings and abortion. >> what i can't understand is with hillary clinton and now senator kaine at her side is to support a practice like partial birth abortion. >> governor, why don't you trust women to make this choice for themselves? >> reporter: a contentious debate. america's first and last chance to see the vice presidential nominees on the same stage.

>> reporter: the fact checkers busy overnight. they say kaine oversimplified donald trump's stance on nuclear weapons obtained by other countries and penn undervalued how much money the clinton foundation gives to charities in terms of their programs. they also say he ignored some things that donald trump actually said, things he denied during that debate last night. >> interest iing to see them. as wildfires surge across the nation, the white house is making a new push to increase funding to fight those fires. in the budget here ending last friday, congress provided an additional $622 million to the u.s. forest service. that money was used to offset firefighting costs which have ballooned due to climate change and drought. a dangerous time right now for fires. we are getting a break in the weather. rob, cooler weather again today, but that's going to change. >> typical for fall, a bit of a roller costar ride in the

seven-day forecast. look at the pre sunrise views, 45 degrees in napa. that's a gorgeous view from sbrun know mountains. 53 degrees, clear skies. some of our peninsula micro climate, 45 in redwood city. south bay mid 40s. downtown san jose you also are looking at clear skies this morning. temperatures in the upper 40s moving probably about 30 degrees of warming between now and the numbers climbing. those are san francisco temperatures near 80 by saturday. our valley seeing numbers today in the 70s, 80s tomorrow. closing in on 90. feeling more like summer to start the weekend. >> we have water to cool some folks off. it's not a good issue in berkeley. we'll talk about that after i show you the rest of the bay. the south bay build is on typical, except for 101 at trimble whereby there's a crash on the shoulder and additional activity.

the distraction is there. approaching the bay bridge, most of the east bay looks standard. watching university connecting you from the cal campus towards the eastshore freeway, grant still, the water main break repair work going on, restricting access on university avenue, one lane in each direction. that will be an issue. take sacramento over to cedar, that will get you clear of that. we'll track this and give you more updates coming up. back to you. >> we'll look forward to them. thanks, mike. more bay area lakes now off limits to swimmers. the reason people are being told to shea onshore. we already know mammograms are one of the most effective ways to screen for breast cancer. could the critical exams also detect another deadly disease? that story next. the magic number that seems to be the difference between making it and not making it in the bay area. take you to the big board, dow industrials gaining 92 points.

we can't go back to the years of devastating cuts to public education. exactly why i urge you to vote yes on prop 55. prop 55 prevents $4 billion in new education cuts without raising taxes on anyone. and there's strict accountability in prop 55. with local control over school funding decisions. and mandatory annual audits guaranteeing the money goes directly to our classrooms. not to bureaucracy, not to administration. so vote yes on 55. because it helps our children thrive.

they prey on our children, spending billions. addicting 17,000 california kids each year. eventually killing one-third of them. now tobacco companies are spending millions to... defeat prop 56. because in every state that's raised tobacco taxes, smoking rates go down. so who are you going to trust? pediatricians, cancer groups and the califronia pta who all... support prop 56. or the tobacco companies trying to kill it. vote yes on 56.

is at-risk. ero in san francisco ==sam/vo== "national trust for historic preservation" says the water the embarcadero in san francisco is at risk. the chronicle reports the national trust for historic preservation says the waterfront faces threats from earthquakes and sea level rise. it's on the list of the 11 most

eng dangered historic places in the country. tides are expected to be 66 inches higher in the year 2100 than they are today. it could cost billions to secure the seawall for the next hundred years. stay out of the water. two more east bay lakes are hit by toxic allergy. lech temescal and quarry lake are both closed for swimming. the list grows now to five. lake anza in berkeley has been closed since august. visitors are warned to swim at their own risk at lake del valle. could mammograms screen for heart disease as well as breast cancer? researchers say it is possible. small calcium deposits that show up on routine mammograms may indicate increased risk at other serious health problems. women in the study were more than twice as likely to develop coronary artery disease and more than three times more likely to

have a stroke. new medications used for hepatitis c can have deadly consequences for people who previously had hepatitis b. fda regulators issued the most serious warning in their arsenal. the fda requires the makers of nine different hepatitis c drugs to label those potentially deadly side effects. you buy your fit bits with high aspirations to be active and track your movement, researchers say wearable fitn, s they say people with no cash incentive didn't krien crease their activity and nearly half were no longer wearing the deaf viegs. the cash report group did increase their activity at first, but became even more sedentary after the money was taken away. >> the reward isn't just getting in shape i suppose. 6:46. people living in the sinking and leaning millennium tower have
