businesses. first fire in mid july, the 15th this past weekend. almost all the fires have been set on weekends, from saturday evening to sunday morning and sunday evening to monday morning. ten of the fires between 1:00 a.m. and 5:00 a.m. >> it was very scary, and i was driving and i saw burnt trees. it's amazing. we live in a good neighborhood. you don't expect anything like that here, right? >> reporter: police also don't know yet what the motive is as to what would compel someone to set all these fires. reporting live in fremont, bob redell, "today in the bay." >> thanks so much, bob. in the meantime at 4:33 this morning. millions of people across the east coast are being told to prepare quickly this morning as hurricane warnings go up along florida's atlantic coast. category 4 matthew is moving closer to shore. this is some of the devastation

according to police it happened at the intersection of 15th and euclid street. over the weekend. measure b rolled out four years ago and has been the focus of controversy ever since. over time costs in the meantime have tripled for the san jose police department. officers now average about 450 hours of overtime each year with some shifts still unfilled. voters are going to decide on measure f on the november ballot which is a compromise initiative that would negate some of measure b's rollbacks. >> 4:35 right now. people living in the sinking and leaning millennium tower have nothing to fear in the event of a powerful earthquake. that's the word from a consultant hired by the tower's developers. it concludes despite findings by

nbc bay area's investigative unit, the building is still safe and not at risk of collapse. that same consultant issued another report two years ago with a less favorable outlook. temperatures up a tick today. that's the preview of what's to come. >> right now you'll certainly want a jacket as you head outdoors. 40s and 50s outside. as we head towards the weekend, 80s and 90s in reach across the bay area. a look at that and our forecast coming up. >> looking over toward -- a spider at the bay bridge. also road crews working. that spider is not on the roadway. we'll talk about what is coming up. >> thank goodness. that's a big one. money could make a big difference for homeowners coming to grips with damage from the loma fire. ow how santa clara county is determined to help out.

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.

this was quite a sight in new jersey yesterday. look at that, two homes virtually flattened in a gas explosion. it was all caught on tape in patters patterson, new jersey. reports came in early yesterday morning when first responders arrived, about 9:00 eastern. they could hear the hissing sound from the gas leak. firefighters immediately started to evacuate all the people in the buildings there. they managed to get everyone out within 15 or 20 minutes before those buildings exploded. staying in new jersey, investigators have successfully pulled a second data recorder from a deadly train crash in

hoboken. that first black box turned out to be black. the second recorder is now being tested. investigators have also recovered front-facing video and a cell phone belonging to the train's operator. back in the may, a man accused of torturing and killing cats is awaiting his fate. yesterday 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 kalgts in a san jose neighborhood. he's due in court for sentencing facing up to 15 years in prison. investigators say it will likely cost $2 million to repair a historic church destroyed in the fire. there was severe damage to the roof and second floor. the congregation continues to hold services at a church across the street. investigators do not believe it was arson. 4:44 right now. one game, two very powerful

pitchers. win and move on, that is the deal for the giants in the wildcard match-up against the new york mets. >> two super powers. the giants held a workout at met citi field, the second time they've played in a one-game wildcard. their track record here, really good. the last time in 2012 they beat the pirates en route to a championship. >> i love it. i have to. we have a ring because of this wildcard, and i have a chance now. >> we have to find a way to score more runs than they do. >> very insightful there. that was madison bumgarner. he's squaring off against that man right there. they call him thor. the reason, because of those flowing lochs, 6'5", 250, syndergaard finished the year with 14 wins and the third best e.r.a. in the national league. two of the best pitchers in baseball squaring off. bumgarner had the fourth best

e.r.a. let's take a peek outside this morning. oracle arena where the future of the warriors has arrived. for the fans, the wait well worth it. the first chance forwa warriors fans to see kevin durant. he delivered. he scored 21 points to help lead the dubs to a win over the clippers. got to remember, though, we're getting excited, but it's preseason. fans say adding durant to the mix is simply a winning recipe. >> chemistry with all those new players, they seem to be meshing pretty good tonight. >> they're at home. everything happens at home. >> i think durant is going to be great. he might be the best player on the team. curry has been our heart for years. >> adding to last it in's excitement, steph curry bobbleheads. mike inouye showed them to us yesterday, a little preview. the warriors play at the shark tank tomorrow where you get another bobblehead if you're

lucky enough to go to that game. >> the klay thompson one. >> right. and with a hockey stick. >> normally you'd say temper expectations. it's a pregame. don't temper expectations. turn up the heat here for the season. not yet? >> bay area, big changes as we head towards the weekend. all eyes still on what's happening with hurricane matthew overnight. it did weaken as it crossed the eastern coast. winds down to 115 miles per hour. forecast to strengthen on approach to south florida. here are the active hurricane watches and warnings up and down the florida peninsula there. the bahamas going to get a big impact from the storm. you the see the projected path approaching wiech as we get into thursday night. curving toward the north towards south carolina and north carolina. notice the northeast might be dodging the first round of the

storm. i say first round. overnight half of the computer models now send this storm on a loop off the southeast coast. so something we'll have to watch closely. we could be dealing with the storm for a while as it makes a run towards florida. it could make a second run back around the bahamas as we move through the next 48 hours. right now temperatures in the 40es and 50s outside. for the afternoon, highs in the mid 70s today. a little warmer than the highs we saw around here yesterday. upper 60s in san francisco, clear skies making for a chilly start to the morning, but a nice mild afternoon. across the north bay, numbers in the upper 70s, same story for the tri-valley and walnut creek as the temperatures climb a few more degrees from yesterday, and for thursday and friday, here is where things will be warming into the weekend. a ridge of high pressure keeping rain out of our neighborhood. you'll see that. we'll continue to head off to the north. now temperatures are climbing for places like san francisco. still thinking we'll get to 80 degrees on saturday. 70 starting tomorrow.

look at the inland valleys starting tomorrow into probably low 90s on saturday and still staying in the mid 80s through sunday. >> we're getting to try out our whole wardrobe. looking toward the bay, you can drive the whole bay and not really have a problem. over in the altamont pass, west 580, typical slowing. we're focusing on berkeley. want to make sure you heard that university avenue is open for both directions over at grant. that's between cal and interstate 80. that's the eastshore freeway. that's a critical portion of the roadway. yesterday about 12:30 is when the water main break happened. it has reopened. limited access. hopefully all lanes open by the bulk of classes starting. no delays reporting for b.a.r.t. about 25 trains on time now. we're looking to the south bay where traffic flows well, this is 101 at 680.

behalf of the government. yahoo! built a system last year to scan all e-mails for certain words and phrases, done without the knowledge of yahoo!'s security team. it led to the departure of the chief information security officer. twitter is expected to start fielding takeover bids this week. salesforce.com could make an offer. google, disney and microsoft may also be interested. twitter could fetch up to $20 billion. no guarantee a deal will be reached. sam and laura, back over to you. >> thank you very much. 4:51. promising lots of benefits of the mammogram. how the test is detecting possible heart disease as well as cancer. we'll show you how it works coming up. happening right now, after several jewish residents in lafayette were rattled when a man in a santa hat was seen

(coughs) that cough doesn't sound so good. well i think you sound great. move over. easy booger man. take mucinex dm.

it'll take care of your cough. fine! i'll text you in 4 hours when your cough returns. one pill lasts 12 hours, so... looks like i'm good all night! ah! david, please, listen. still not coughing. not fair you guys! waffles are my favorite! ah! some cough medicines only last 4 hours. but just one mucinex lasts 12 hours. start the relief. ditch the misery. let's end this. haer good wednesday morning to you. 4:54. this year's election has the attention of voters and hackers. in fact, security experts say there's a real possibility someone could hack our vulnerable voting system. now a solution is being developed right here in silicon valley. senior investigative reporter stephen stock joins us to explain. good morning, guys.

it may sound counterintuitive, but the experts we talked with about this hacking problem says one way to make sure the systems are secure is to make the computer code that runs voting systems open for public inspection. the problem with the current systems in use today are that they are old and antiquated. they date back to the 2000 presidential election and that hanging debacle in florida. you remember that. those machines are based on old pc computer technology. experts say they are vulnerable right now to hackers. the same experts tell us the way to combat that is to adopt new machines that rely on open source code to run them. in other words, computer code that everyone can check out for bugs, vulnerabilities, even hack them themselves and fix those hacks. san francisco and los angeles counties have already agreed to spend millions of dollars to begin developing and using those systems for the next presidential election. meantime, california secretary of state tells me precautions

have been taken to secure the systems being used for this presidential election. if you want to learn more, you can see our entire series of stories on this issue. just go to our web page, nbcbayarea.com and click on the investigative unit. back to you. >> thank you, stephen. if you have a tip for our investigative unit, you can give us a call as well, 1-888-996-tips. or send an e-mail to theunit@nbcbayarea.com. possibly a groundbreaking health development. could mammograms screen for heart disease as well as breast cancer? new research says it's possible. small calcium deposits that show up on routine mammograms may indicate an increased risk of other health problems. researchers followed 1,000 women with breast calcifications. over the next ten years, these women were more than twice and likely to develop coronary artery disease and more than three times as likely to have a stroke. your first fit bit might not make you more healthy.

researchers say wearable fitness trackers are unlikely to boost long-term physical activity. researchers say after six months people with no cash incentive didn't increase their activity and nearly half were no longer wearing the device. >> show me the money. >> cash reward group did increase its activity at first but became more sedentary when that was removed. hot air balloons over new mexico, a spectacular sight. thousands of people have been waiting patiently to see this. the albuquerque international balloon festival had to be canceled because of high winds. the day before two balloons hit power lines and grounded the show. dozens of balloons are back in the sky with some of the brilliant colors, an amazing sight to see. i talked to you about my bucket list a lot.
