years of negotiations - a nuclear agreement with . history in the making. after years of negotiations, a nuclear agreement with iran is reached. the latest from the white house. debating some of the strictest safety regulations in the state following last month's deadly balcony collapse. >> and what a road trip. nasa's new horizon probe reaches plu pluto. from nbc bay area, this is "today in the bay." >> it is an action-packed tuesday morning. thank you for joining us. it's 4:30, i'm sack sam brock. >> i'm laura garcia cannon. first let's check the forecast. >> good morning. we all get the red memo this

morning, apparently. as you walk out the door, we're feeling temperatures in the 60s across most of the bay. and mostly clear skies, and in the north bay, it's cool. 56 degrees as you start out the day. and as we go into the afternoon, another nice day, but slightly warmer than yesterday. especially in the north bay and in the tri valley, reaching 86 degrees in the north bay. san francisco, about the same as yesterday. peninsula, 79 degrees. and the south bay, topping out at 84 degrees. temperatures going up the next couple of days. i'll show you that coming up in the microclimate forecast. good morning, mike. >> i think that red was inspired by the temperature mappings you have coming up. looking here, not because of the red lights, tail lights across the san mateo bridge. no surprises. san mateo bridge in the middle but the entire bay what you would expect. i'm watching a crash on the peninsula, northbound 280 at hickey boulevard. a crash off into the vegetation. no injuries reported, but we'll

watch that. i feel bad for the vegetation. back to you guys. >> thank you very much, mike. 4:31 now. new this morning, historic moment in relations with iran. you just heard from the president of the united states moments ago, if you caught it. a landmark nuclear agreement has been reached. >> at midnight no, less. it was a short time ago in vienna, iran and the six western nations. the five world powers, plus germany, negotiating that deal that announced the agreement. economic sanctions will be lifted in return for iran curbing its nuclear program. the deal caps more than a decade of negotiations or i should say, many years of negotiations, and some believe it may transform the middle east. now congress would still need to approve the deal. our d.c. correspondent, tracie pot potts, is following the latest developments and will bring reaction from the nation's capitol with an update at 5:00. it is 4:32 and happening today, some of the strictest safety regulations in the state will be up for debate in

berkeley. this follows last month's deadly balcony collapse. "today in the bay's" kris sanche sanche sanchez. >> berkeley is talking about changing actual construction but also changing policy, holding not only builders responsible but putting onus on the city itself and its inspection process. let's start with the physical changes first. as we saw in the video following the june 16th balcony collapse, beams supporting the balcony were made of wood and an investigation reveals many were compromised by dry rot. the berkeley city council is proposing going forward those beams be built with something more durable or perhaps more protected against the weather. additionally, the council wants better design standards to protect the integrity of the construction from exposure to weather, as well. one councilman will also push for more frequent inspections and that's a change that would have given any balcony or would put any balcony under the mike scope every three years every

instead of five. additionally, a construction bill that would force construction companies to disclose any of their past problems, that's up for a critical vote in sacramento today. no surprise here. the assembly members representing berkeley and san mateo, hancock and jerry hill are pushing for this measure. under that bill, construction companies would have to reveal any past penalties they have had for construction mistakes or fraud, and they would have to reveal any lawsuits against them, as well. perhaps do not need to remind you, six people were killed when that balcony collapsed. seven others were injured. and some of them are still recovering. again, the berkeley council talking about that today. and that assembly vote is also scheduled for today. sam? >> hopefully this will save lives. thank you very much. a bizarre kidnapping case thought to be a hoax now takes another turn. the man accused of being the mastermind behind it all is now behind bars. matthew muller was arrested by authorities on june 9th in south

lake tahoe. police believe he kidnapped denise huskins and quinn after all in march. police say he broke into the home and the owner fought back. meantime, we're learning more about his past. he was diagnosed with bipolar disorder and his attorney says that troubled past has been following him for a while. >> mr. muller is in a very difficult place. he is facing state charges, he's facing federal charges, and those are very difficult for any person, certainly a person with a mental disease. >> the couple's attorney says vallejo police should now apologize to their clients. and not just vallejo and dublin. the feds say muller might be linked to unsolved crimes on the peninsula. they say he was conducted to a burglary case in palo alto back in 2009. a young woman was bound and blindfolded in her home. however, no charges were filed. also in 2009, mountain view police investigated a similar home invasion robbery involving

a masked suspect who restrained and blindfolded victims. with a degree in harvard, muller has practiced law in california since 2011, but in january it was recommended he be disbarred. a hearing is set for next week. his pending disbarmentáz a disp in an immigration case. of course, head to nbcbayarea.com to read the 56-page affidavit detailing all of the evidence in this case. just click on the top story box. you can also find the latest updates in the case by downloading our free nbc bay area app. homeland security secretary jeh johnson facing questions this morning following the shooting death of a woman in san francisco allegedly by an undocumented immigrant. surely you're familiar with that case now. johnson and the house judiciary committee will talk about how to enforce u.s. immigration laws. kate steinle died earlier this month while walking with her dad on pier 14. juan lopez had been departed

treasure island exit. it took crews an hour to put the fire out. investigators believe a cigarette may have started the flames. traffic on the peninsula may have been moving a little slower than usual this morning. that's because lanes between university avenue and embarcadero road on southbound 101 were closed overnight. it's part of that $18 million expansion project to replace the bridge over san fran sis quoto creek. the same area will be closed from 9:00 tonight to 5:00 tomorrow morning. flooding at the creek, pesky. every now and then it just pops up on you. we're keeping an eye on that and also looking to see what your weather is like to start your tuesday. >> that's right. we're all in the red here. get some red-hot temperatures? >> yes. we have a couple days with the temperatures just ramping up gradually. thursday is when the heat peaks. and as we get a live look now at san jose, we do see that there's

will ever get to the icy dwarf planet. we'll have only 30 minutes to take pictures of the surface and its largest moon and taking chemical readings. new horizons left earth on a journey that is 3 billion miles long. on thursday, the spacecraft sent back these images of pluto. it shows a planet that is unexpectedly peach in color, and has dark and light regions across its face. scientists are still trying to figure out what these images mean and hope it gives them clues to the origins of our solar system. >> i think this is a great example of a great society and a great nation and what great nations do. and i have to tell you, the data we're going to produce -- in fact, the data we're already producing, is a gift for the ages to all mankind. >> reporter: and again, right now as we speak, new horizons is making that crucial fly-by past

pluto, again, just around 7,800 miles away from the planet, only 30 minutes for taking pictures. and right now we're awaiting for a live view inside the progress, new horizon's control room. and it looks like -- i guess they're cheering, celebrating over the fact that they have gotten this close to pluto. that the spacecraft is still sending back signals. unfortunately, because it's over 3 billion miles away, as you can imagine, it takes time for radio transmission to get back to earth. they're estimating around four hours. i'm starting my stopwatch now and i hope you'll stick with me for four hours looking at my pretty face as we expect the wonderful images to come back. and i'm hoping, sam and laura, you can tell me, scientists throwing a party. what's going on back there? >> gone wild. >> we saw bill nye the science guy and they're waving american flags and now listening
