this is a live look at sfo. a little bit of fog on the bay. hello, everyone. i'm michelle griego. >> hi, everyone. i'm frank mallicoat. did you say it was friday? >> i said it was friday. >> no, you didn't, i did. congratulations. >> i did say it was friday. >> did you? [ laughter ] >> didn't hear it. all right. >> are you awake? >> we're all waking up with you. it's 4:30. >> it's a foggy friday. she nailed it. we have fog. if you look at our transamerica pyramid shot, you can see the ceiling is about 600 feet. when it's that low, we are guaranteed delays at sfo on arriving flights. good morning, boy, after highs all the way up into the low 80s yesterday, it will be cooler and partly sunny. yesterday it was 75 in san francisco. today 61 degrees.

yesterday we saw delays early along 4 because a lot of folks were using that instead of bart. today we are still dealing with the closure between north concord and pittsburg-baypoint. bus bridges are in place. bay bridge quiet out of oakland into san francisco. just a few cars stuck in the cash lanes. a frustrating commute in store for bart riders again today. a rare piece of equipment keeps breaking down and putting trains out of commission. anne makovec is live at the north concord station where delays are significant and shuttle buses are the only ride around. what's the latest, anne, good morning? >> reporter: the bad news is bart still cannot figure this out. they are flying in experts today to try to help them find out the problem with this part of track. in the meantime, this bus bridge will be in place through the weekend. people will have to board buses

like these to get between the north concord and pittsburg- baypoint stations in contra costa county. so bart's advice, add 30 minutes to your trip. bart shut down that section of track after power surges damaged 50 train cars on wednesday. bart's engineers still can't figure out why. >> you have test trains running to take measurements and if it looks like we can safely move train service between the area we'll do so but right now buses, allow extra time and the bigger impact systemwide is there are definitely less cars available. >> reporter: so 50 cars were knocked out of service this week, 80 cars were benched two weeks ago because of a similar mysterious surge problem in the transbay tube. so bart is running shorter trains so they are packed with people. that's affecting trains systemwide.

we'll talk to them this morning coming up in the next half- hour. frank and michelle? >> what will it take to get the cars fixed? >> reporter: bart is ordering this specific part that they need for the cars. normally it takes about five months to get that part in. they are working with the manufacturer to try to make that a shorter time. it will cost about $100,000. live in concord, anne makevoc, kpix 5. we wanted to see firsthand what's getting fried when bart tracks face a power surge so we sent kpix 5's mike sugerman straight to the bart yard. >> so you can see that hockey puck kind of design in there. reporter: this little gizmo is causing huge headaches for bart and riders. every once in a while before they close this section of track, sometimes it blows out. that's weird. >> strange. >> reporter: bart mechanic timothy ryan has never seen

anything like it before. few have. >> imagine plugging you 110- volt vacuum cleaner or hairdryer into a 220-volt outlet. that's what's happening. >> reporter: why? they don't know. but it's put 58 trains, 10% of bart's daily minimum, out of service. >> so we can't run trains through there or we'll lose more. >> reporter: it's unclear how long that section of track will be closed with buses in their place but replacing that little thigh wrister it costs $1,000 each. about 120 have blown out so far. it takes 22 weeks to get a new one. talking about months? >> months is a very realistic estimate. >> reporter: this is how bart explained things to its passengers on its twitter account. "bart was built to transport far fewer people and much of our system has reached the end of its useful life. this is our reality." the next few months it's going to be even worse. in concord, mike sugerman, kpix

5. ever wonder what $9 million in el nino storm damage looks like? take a look at this. the santa cruz county board of supervisors says these washed out roads will require significant repairs. next week the board will consider whether to declare a local emergency there, which would allow it to seek funding relief from the state. we are getting a little relief from el nino for a while, right? >> we are except for the rain will be coming for sure on monday. now we are playing tag with the sunday forecast. i have it in the forecast last monday, tuesday and yanked it because it's delayed. now it's picking up speed and we don't want that because we have the palm sunday mass processions and the running festival. so we have a lot of outdoor activities and sunday could be impacted by the rain. sfo in a deck of low clouds that will certainly cause airport delays on some arriving flights this morning. we are in the 40s and 50s. it's currently 48 in livermore,

light winds. forecast high today in san francisco 61. the average is 62. so i would say this is going to be rather a very typical winter day here in the bay area after realizing highs well above normal yesterday. 60s and 70s with partly cloudy skies around the peninsula, 73 morgan hill. east of the bay 60s and 70s out of the 80s experienced yesterday. balmy on thursday. 60s common north of the golden gate bridge. 70 in napa. we'll see clouds thicken up across the northern portion of the bay area. rain for the weekend. we're tracking that together coming up shortly but right now, let's send it over to "lady g." >> good morning. let's jump over to highway 4 get a look at our maps here and check conditions as you work your way out of antioch and pittsburg this morning. we saw delays yesterday as people are not using bart because of the troubles this morning and using the roads instead. right now it's early. the morning commute just getting started so things are good on the westbound side on speeds. drive times not too bad.

bus bridges are in place. give yourself 30 extra minutes with bus bridges in place. there is a 10-minute delay on trains from pittsburg-baypoint into san francisco. now, the rest of mass transit is on time and the rest of our freeways are looking pretty good this morning including the bay bridge. new details this morning on the search for a bay area woman suspected of murdering her 90- year-old mother and stuffing her body in a trash can. investigators think that alicia osivin changed her appearance hiding as a man in los angeles. here's what she looked like the last time anyone in the bay area saw her. police found her mother mary's remains shot to death. it's unclear how long the body was in the trash can but neighbors said they hadn't seen

mary or her daughter since august. police still don't know the possible motive but they are convinced they are after the right person. >> they live together, daughter is gone and a number of factors that show that mother was murdered and the daughter hasn't been seen or heard from since. originally we did enter her as a missing person, as well. maybe something happened to her too. >> here's another look at alicia osibin. she may be going by the name alex calico and dressing in men's clothes. she is considered to be armed and dangerous. how do you stop so many people young people from being killed in richmond? that's what christin ayers asked the interim police chief. reporter: february 29 a burst of gunfire on a trail outside jfk high school. officers told family members 14- year-old xavier mcclanahan was

the victim. within two weeks, two more homicides. >> we try to get between law enforcement and these young men to try to deter these men from -- violent young men. >> reporter: his work is more difficult in richmond. the city had 11 homicides in 2014, a 30-year low. but last year, the number of murders nearly doubled to 21 and this year, there have already been six. >> that's a little bit ahead of where we were at this time last year. >> reporter: richmond's interim police chief says the city is gripped in a cycle of retaliation. his officers have been trying to disrupt it with more officers on the street focusing on known criminals. >> we have been, you know, reasonably successful in at least, you know, slowing down, you know, escalations and then in terms of, you know, focusing on the folks we think are involved. >> reporter: richmond police

have leads but no arrests in those six homicides. local leaders say police can't do it alone. they need the community's help. there's just one problem. money. >> we have been doing this without funding. you know? you just got people who love their community doing this work. >> reporter: bernstein says the community outreach program known as cease-fire has helped stem the violence but relies too heavily on volunteers. >> we are seeking funding, which will give us a cease-fire coordinator, possibly some case managers and then we gonna redesign the cease-fire model where we become more, um, you know, engaged in the community. >> reporter: chief brown says changes are happening in his department too to keep up with the spike in homicide. >> it's the same playbook but it's constantly being tweaked and adjusted for what's happening now. >> reporter: in richmond, christin ayers, kpix 5. the fbi is now saying the bay area college freshman who

trump won the primary in florida. rubio's home state. trump now has nearly half the 1237 delegates needs to clinch the gop nomination. >> we have to bring our party together. >> reporter: trump warns any plans to derail his candidacy could lead to riots. but on thursday, a group of conservative activists and lawmakers met behind closed doors to discuss alternatives to the gop front-runner. senator lindsey graham threw his support behind his adversary ted cruz. >> i think the best alternative to donald trump to stop him from getting 1237 is ted cruz and i'm going to help ted in every way i can. >> donald trump has -- >> reporter: the activist group anonymous has trump in its crosshairs saying it posted the businessman's personal information online. on the democratic side senator bernie sanders conceded the missouri primary and campaigned in arizona thursday night. >> with your help on tuesday, we're going to win here in arizona.

santa rosa to the north. an area of low pressure is strong with great dynamics with it. this is the core of the center of the area of low pressure that contains the most instability. then this is the frontal boundary that's going to be producing some clouds in our area. that's been bouncing off the huge dome of high pressure and high pressure has been winning out. but now the low is going to see some movement. the storm track will be returning to the bay area on friday according to our wind particle map. here you see by sunday 8 a.m., some light rain in the north bay. so if you have palm sunday processions outside in the far north bay, you will need your umbrella. otherwise partly to mostly cloudy skies around the bay area. rain sunday night into monday. today 75 at sacramento. it's springtime skiing in the greater lake tahoe area with
