spoke to several parents who hope to put a stop to the violence. >> reporter: i'm here at montgomery high school in santa rosa where parents are reacting to a growing concern about school safety. they're telling me it's time to bring back the school resource officers to the campus. melissa stewart is a long time santa rosa resident. her number one concern now is her children's safety at school. >> the tipping point was realizing that there was not safety protocols in place that we felt like the school district should have implemented. >> reporter: that tipping point pushed her to create a parents group called the safe campus alliance. on thursday she met with other members to say enough says enough just a day after a 14-year-old student was arrested for allegedly manufacturing firearms using a 3d printer. >> it's what's happening in sonoma county and a lot of

cities. it's not just a montgomery high school issue. ghost guns are a real thing. there's adults and teenagers that are printing these and getting them on our city streets. >> reporter: melissa says there needs to be a more aggressive approach to keep students safe. >> i keep thinking we can do better. i know we can do better. so that's what keeps us going. we believe all students should feel safe at school and they don't right now. >> reporter: just like rebecca sullivan, she works as a health technician at montgomery high school where her 16-year-old daughter attends. >> i think about that every day like if i wasn't there and my daughter was in a lockdown or another stabbing happened or god forbid, a shooting happened, you know. i would never forgive myself if i just quit right now and left my daughter there on her own to deal with it. >> reporter: rebecca, who is also a member of the alliance, says it's time to bring back the school resource officers to the campus. >> we saw how easy it was to bring an sro back on campus.

our district did that overnight after last year and it was a good thing on our campus and we saw the reaction that our students had to having an sro. they were grateful. >> reporter: melissa agrees. she says students deserve to return to a normal life. >> they're facing the issues, but they want to move on with their lives and want to come to school and not have an active shooter or weapons or gangs. >> reporter: they agree something needs to be done as soon as possible to avoid another tragedy. >> the school district declined to comment on that arrest saying it had nothing to do with anything the student did at the school itself. i'm anne makovec with details on a huge weapons bust in the east bay, machine guns and 1 million rounds of ammunition all owned by a man who is legally barred from owning weapons according to the

attorney general releasing this video from the man's home in richmond, where state and local officers convened on january 31st along with the bomb squad from travis air force base. they found 11 machine guns, 60 assault rifles, dozens of other firearms and about 1 million rounds of miscellaneous caliber ammunition. they credit a state database for helping them find this stash. it's called apps or the armed and prohibited persons system. it identifies people who had firearms and later became prohibited from legally owning them. that includes people convicted of a violent crime, were placed under a restraining order, or suffer from serious mental illness. california was the first state in the nation to establish a system like apps. the state has not released the name of the man at the center of that richmond bust. we now know the identities of the two children and two adults san mateo police say were killed in a murder suicide. anand henry and alice

benzinger were the two adults and the children were their twin boys. police found the family monday morning during a welfare check at that home. it appears hen rimshot benzinger and then himself. the cause of the boys' deaths is still being investigated as to the motive for those killings. kansas city police say the shooting after the chiefs super bowl parade is likely connected to a dispute that led to that gunfire. one person was killed, 23 injured, many of them children. cbs' charlie demar with the very latest. >> reporter: police say this tackle in the crowd after wednesday's super bowl parade in kansas city helped detain one of three people who may be connected to the shooting, two of them juveniles. >> preliminary investigative findings have shown there was no nexus to terrorism or homegrown violent extremism. this appeared to be a dispute between several people that ended in gunfire. >> reporter: this was the moment rapid gunshots rang out at the gathering of close to 1

million people. chiefs fans had to duck and run for cover as more than 800 police officers on scene sprang into action. >> i immediately told him get down, get down. that's shots fired. >> and there were a bunch of kids and my sister and i were running telling them get down, get down. >> reporter: lisa lopez-galvan, mother of two and popular radio deejay, was killed, more than 20 others injured, most of them shot, including nearly a dozen children. >> out of all the children we treated, we only have three left in the hospital, all which of who will recover from the injuries they had yesterday. >> reporter: thursday police thanked the men responsible for the post parade tackle, including filder who was there with his family. >> there was a huge commotion. people are yelling, get him, get him. i reacted without thinking. >> reporter: police say they have recovered several firearms

and their investigation continues. >> of the three people initially detained, police released one that they say was not involved. two juveniles do remain in custody. a brief shelter-in-place at napa's vintage high school this morning after dozens of students fell ill. it happened during first period during choir class when 20 students reported feeling nauseous. one of the students even fainted. that prompted the students to go into a shelter-in-place while fire crews checked the campus. >> we evaluated the buildings and went through all of our checklists, checking for co, hydrogen cyanide, any other potential causes and we also had pg&e come out and we also checked the hvac system, went through all of our checkpoints and we didn't find anything. >> six students were taken to the hospital, no word on what caused them to get sick. turning to weather now, a pair of power of storms taking aim at the bay area. we're

getting a little break today in the rain. as we check in with first alert chief meteorologist paul heggen, it's kind of the calm before the storms. >> yeah. calm between the storms because we had rain yesterday that was just kind of gentle rain compared to what we've had recently. we are in for much more rain as we head into presidents' day weekend. it's been a mix of clouds and sunshine over the bay area today. we do have the clouds turned on in our floor map as well, some patches in between those clouds, but very little shower activity. that changes as we head into presidents' day weekend as back-to-back atmospheric rivers, the channels of air that direct tons of moisture through the atmosphere overhead, they will soak the bay area, the first one arriving saturday is and the next one lining up in the pacific and will surge in on its heels sunday night and monday. we'll look at the radar simulation from futurecast in the background, but here also tracking hour by hour the amount of rain we'll see and the wind gusts with

these storm systems. we'll advance to when the first burst of wind and rain arrives. that's going to be saturday. we'll pick up a quick half inch to an inch of rain for most of the bay area. wind gusts will likely peak in the 20 to 30-mile-per-hour range. as we head into sunday night and monday, though, more rain will fall adding another half inch to an inch at that point in storm system's evolution with wind gusts over 30 miles an hour and monday afternoon peaking in the 35 to 40-mile-an-hour range. as the soil is saturated and the tree root systems can't grab onto that saturated soil, it's more likely we could see at least sporadic power outages as some trees come down monday and it looks like the rain continues into tuesday and lingering showers into next week. we'll look at the rest of the bay area and rainfall totals we expect through the duration of these systems coming up in a few minutes. we're less than three weeks away from primary elections here in california,

several candidates seeking to replace the late senator dianne feinstein now separating themselves from the pack. >> she brought a tremendous amount of gravitas to that job. so filling those roles is going to be nearly impossible for anybody. >> at 5:30, what you need to know about the top contenders before heading to the polls. the san jose regional medical center plans to permanently close its level two trauma center due to declining use the last few years. instead they're focusing on their emergency services, announcing plans to invest $10 million in the department to increase the number of beds from 43 to 63. mayor matt mahan said today while he's happy about the increase in beds, the news is still concerning. >> we don't ever want to see life saving medical services cut, particularly in our lower income neighborhoods. east side san jose will have to travel farther to get to a trauma center, which is concerning. >> the hospital plans to close the trauma center on august

12th. raging waters in san jose could be making another big splash if city council approves a new plan to reopen it, this after officials say they found a new company to take over management of the water park. last year the water park did shut down after the last operator terminated its lease with the city. raging waters could reopen as soon as this summer if the plan is approved. oakland has a new home for professional baseball and it has nothing to do with the as. and a frightening explosion, what likely caused that blast. and a deputy opens fire on his own patrol vehicle with a handcuffed man inside, why it appears that an acorn is to blame.

this ad? typical. politicians... "he's bad. i'm good." blah, blah. let's shake things up. with katie porter. porter refuses corporate pac money. and leads the fight to ban congressional stock trading. katie porter. taking on big banks to make housing more affordable. and drug company ceos to stop their price gouging. most politicians just fight each other. while katie porter fights for you. for senate - democrat katie porter. i'm katie porter and i approve this message.

democrats agree. conservative republican steve garvey is the wrong choice for the senate. ...our republican opponent here on this stage has voted for donald trump twice. mr. garvey, you voted for him twice... as your own man, what is your decision? garvey is wrong for california. but garvey's surging in the polls. fox news says garvey would be a boost to republican control of the senate. stop garvey. adam schiff for senate. i'm adam schiff, and i approve this message.

a wild story out of florida, a deputy firing his weapon multiple times at a man inside a patrol vehicle after he mistakenly thought he had been shot. well, he was not hit. it turns out an acorn hit the patrol car and the deputy thought it was gunfire. he shot multiple times into the car and another deputy also fired their weapon. this happened back in november when officers got a call of a woman who reported her boyfriend was refusing to return her car. officers searched the man and detained him and put him in the back of that patrol car. miraculously the man was not hurt in that shooting. investigators say he was not armed. the deputy involved resigned from the force in december after an internal investigation found his use of force was not reasonable. surveillance video shows a

semi truck erupting into a big ball of fire. this happened in los angeles. the massive explosion sent at least nine firefighters to the hospital. two are in critical condition. it happened near the ports of l.a. and long beach as crews were putting out what they thought was just a routine vehicle fire. >> the unique aspect of this is that the truck was not powered by the usual fuel like diesel or gasoline. it was a clean air vehicle. it is powered by compressed natural gas or cng. so it had two 100-gallon tanks that are under 3,300 pounds of pressure and those tanks are mounted on each side of the vehicle to power it. >> officials say six minutes after the crews responded to the scene, one of those tanks did explode. the driver of the truck escaped before the explosion and is now cooperating with the investigation. here in the bay area just a sad morning, three people were killed in a crash on the bay bridge near treasure island. this was on the lower deck. this morning investigators say

a mini cooper stalled and called 911 while they were waiting. a toyota tacoma slammed into the car. three people in the mini cooper were killed. the chp says the driver of the toyota was taken to the hospital with major injuries, but is expected to survive. san mateo county officials sent a letter to state regulators trying to prevent the expansion of google's waymo driverless taxis to the peninsula. the california public utilities commissions asked for any objections to the expansion before they make their decision which could be decided in a few weeks. this comes as both waymo and their competitor cruise face growing opposition over safety concerns. in fact, san jose state senator dave cortese just introduced a bill today that would empower local governments to make decisions about driverless taxis in their communities. currently the state gets to decide where these companies can operate. turning to first alert weather, a new fresh coat of snow in the sierra, this is a

look at conditions at palisades tahoe today, looks beautiful. the resort got a foot of snow over the last day. as we check in with first alert chief meteorologist paul heggen, beautiful to look at, pretty scary to drive in. >> right. trying to get up there will be challenging this weekend. tomorrow looks okay to travel. sunday might be okay while we're kind of in between these atmospheric rivers. after that they'll be adding up snow by the foot while we add up plenty more rain. let's look at what you need to know. we've got one more dry mild day tomorrow. savor it. it is short-lived. back-to-back atmospheric rivers for the weekend. storm one arrives saturday continuing into saturday evening. after a brief break the second stronger system moves in late sunday continuing into monday and even tuesday. localized flooding is possible with the amount of rain falling onto increasingly saturated soil. while the winds won't be as strong as the last powerful storm system, there will be enough wind energy some

damage and sporadic power outages are going to be possible. let's track this on futurecast. we start tomorrow afternoon with plenty of clouds, but we're dry until after midnight friday night, light to occasional moderate rain showers to start the day saturday. heavier rain moves in saturday afternoon into the evening, but this will be fairly quick hitting, moving out and leaving lingering showers saturday night through the first half of sunday. it's not going to be raining everywhere. the second atmospheric river will start soaking the bay area heading through saturday afternoon, continuing sunday evening and sunday night. not only are the heavier downpours going to be with us longer, but the wind energy will increase as that system lingers in place. on our precipitation chances chart over the next seven days, you can see how long that system will linger in place, all the green towards the top of the scale, into tuesday before things finally taper off wednesday. how much rain are we talking about? let's look at

the forecast amounts we expect. san jose is expecting a little over 1 1/2 inches of rain over the next five to seven days, could be as little as an inch, could be as much as 2 1/2 inches of rain even in the rain shadowed spots. inland in the east bay expecting generally around 2 to 2 1/2 inches of rain. concord could easily pick up 3 1/2 inches of rain. that's a lot of water. for san francisco the expectation is that 3 inches of rain, but the boom amount if we hit the jackpot is closer to 4 inches of rain. santa rosa, we're expecting almost 4 inches of rain, but again, if everything sets up where the downpours linger longer, we'll see more than 6 inches of rain becoming possible in the santa cruz mountains more than 8 inches of rain looking likely. talk about the wind energy aspects of the system, the wind picks up saturday, but it's a fairly brief burst of gusty

winds not likely to cause significant damage. the winds calm down a little bit, but as the second atmospheric river moves in, we'll track stronger winds heading into sunday and sunday night with monday bringing some of the strongest winds overall, more gusts in the 30 to 40-mile-an-hour range, not as strong as 11 days ago, but still strong enough that wind damage, power line impacts are certainly possible and in the sierra while this first atmospheric river will add up to several inches of snow, a winter weather advisory in effect for them, it's going to be adding up feet of snow with that second atmospheric river moving in sunday and monday and lingering into tuesday. presidents' day i would not travel in that direction. let's bring in the seven-day outlook for the entire bay area, hardly any variation in temperatures. after another dry day tomorrow, there is plenty of rain in the forecast, saturday and sunday, monday rain and wind, more

lingering rain tuesday and finally taper off to lingering showers wednesday and then mercifully dry weather returns to the bay area, but not for a week from today. we'll keep you ahead of it. >> thanks, paul. up next, oakland's newest professional team is getting some fancy new digs, where the ballers are turning a historic park into a modern baseball facility. >> we want this to be one of the premier play spaces for baseball in oakland regardless of the level. top u.s. officials are sounding the alarm about a new russian anti-satellite weapon, the growing concern on capitol hill tonight.
