Reporter officials are not releasing many details about the crash, but it is confirmed that at least one of the victims was a young child. Mayor london breed, who arrived on scene, said witnesses are extremely shaken. You can imagine, children are involved here, thats traumatic for a lot of people who were here and may have witnessed this situation occur. Reporter citys Vision Zero Program is designed to eliminate roadway conditions that could contribute to pedestrian deaths, but there are some accidents that cannot be foreseen, and officials are warning the public not to zum up to any conclusions on this one. We dont know if the driver had a medical emergency. That is all under investigation. So this may have nothing to do with vision zero. Its under investigation. We dont know the cause at this time. Reporter again, two people have been killed and three sent to the hospital with critical injuries. Mayor breed says if anything about this road contributed to the accident it will be addressed but for now sit a matter that is still very much under investigation. In may of last year, a bystander was killed, others hurt, when a car crashed into a bus stop in the citys mission district. And in august an elderly driver struck a family walking near oracle park. Their 4yearold daughter died from her injuries. On average, about 30 people die every year because of traffic accidents in the city.

Reporter the last winter storm left behind a new feature on the mountain that left resort staff stunned. Its the first time ive ever seen anything like that here. Reporter sierra tahoe general manager john rice says strong winds and heavy snowfall formed 20foot high wind lips and helped create this massive crevice about 40 feet deep leading into underground coverages. Essentially like youd see at higher altitudes. Reporter rice attributes some of these formations to the absence of trees on the mountain. The fire in 2021 burned off thousands of them that acted as wind barriers. You can imagine every valley has a river or creek, seasonal creek, and at the bottom that water is running year round. So when it warms up, youll get little areas thatll open up. Reporter im at the bottom of one of the ski list, and middle castle is beyoind the ridge right there. Staff here at the resort tell me they thats they have never seen any formations like that on this mountain before. Despite it being located on the border of the existing boundary on the back side of the mountain, crews worked quickly to fill it in. Snow safety, avalanche blasting a number of different approaches to trying to push that snow in the into those areas and create a ridge to keep people out of them. Reporter while a portion of the run remains blocked off, skiers like eva and her family can rest assured knowing that measures are being taken to keep them safe. Im happy to know that, like, this place is generally safe. Thats why were here. Reporter rice notes adapting to the changing conditions of the mountain is an ongoing process but one that provides a safe and enjoyable experience. Were starting to figure it out, and its still a wonderful product. Theres so much snow this year, did you get to ski in any of this . No, no, you know i just stay here. Yes. We need to know whats happening. Right, and more good news on that. Four days ago we crossed a crucial landmark when it comes to snow in the sierra. We always say what the snow water content is and tell you for that date, like on march 1st we did it and said where we were. The most important number is where we were in terms of april 1st. And we got to 100 of that. So we dont need anymore rain or snow. In one sense i suppose you could say that. Were going to get more. Okay. Let me show you what that map looks like.

Snow on the ground down to around 6,000 feet still up there. Okay but back here at home things started changing today. It was a real pretty day. Watch what showed up an hour, hour and a half ago sitting off the coast. Youre going to see this layer of marine layer cloud right there. Thats coming back in tomorrow. Its like a summer pattern in terms of mornings with the marine layer filling in. That might make a lot of sense if you were outside at all today. Low 70s just about everywhere. Were not breaking records when we do this, but we are five, seven degrees above average for this time of year. And were not getting rid of this until like maybe wednesday or thursday of next week. In fact, monday and tuesday will be a little warmer than this. Thats that live look outside again watching that time lapse. Here comes the marine layer tomorrow morning. It wont be too noticeable. If youre an early riser tomorrow, dont be surprised if you notice a few low clouds. Watch what happens on monday morning. We havent seen a pattern like this like since last summer. Thats the marine layer filling in all of the interior valleys. So were going to wake up on monday morning in march with may gray pretty much everywhere. And it wont last. Its all going to melt back by the time we get to 9 00 or 10 00. Then itll be nothing but blue sky. Remember monday after that melts away is actually the warmest day in the whole sevenday forecast. Well be mid70s on monday. Show you that in the sevenday forecast in one second. In the meantime, theres nothing happening here. We are safely removed from that pinwheel of low pressure over arizona. Were waiting for the storm track to come back. And we already know for like the next five days it doesnt. But by friday of next week it does. Were going to have much more on this as we get closer to it. It doesnt look super impressive, but youre going see theres rain that shows up towards the end of next week, by friday into saturday. Back here weve got scattered showers showing up thatll take us from friday into the weekend. But look what happens back here for the rest of the week. Oakland, youre going to be two degrees shy of 70 degrees on monday. San francisco will be in the mid60s. Lets pull out a few other microclimates here. Going to be 76 in san jose on monday.

Giants beat the guardians 60. The 49ers resigned guard John Feliciano to a oneyear deal on friday. The veteran offensive lineman got a different kind of signing bonus.

He was out early this morning because he chose to stop on the 18th hole last night when play was suspended. He practiced his shot over and over again on the range because he needed to hole this out to make the cut, but it didnt carry over. He hit it right into the rough, and that was the end of his day. Silverman ended up missing the cut. And back to baseball, where you better Pay Attention if you sit behind the plate. Listen to his reaction on the wild pitch. Stays back on that pitch, just serves it the other way. Oh jesus [ bleep ] eddie. He wasnt kidding. He was headed for the exits, and eddie had to watch the rest of the game alone. Look at him go. Hes out of there. I will say this, guy, they put up the nets, you know, all the way down the first and third baselines in baseball. It always amazes me, i dont know how more people, honestly, did not die with all the foul balls that are sprayed to first third base. The nets are probably a very good idea. Even that guy behind it was like im out, im good. But the net was there, right . The net was there. That guy just overreacted. The first and third base side thing, its crazy we went so many years without more injuries. When did they put the nets up . Just a few years ago. Probably smart. A couple bats are going all over the place. Well. All right. Im glad that Major League Baseball is now a safer place. Thank you.
