tell you how hot it will get and how long it will last. it is getting more and more crowded on b.a.r.t. and why the problems are expected to get worse before it gets better.

there's new information about the death of comedian

joan rivers. according to the new york daily news, rivers went to a medical clinic for what was supposed to be routine surgery when a doctor performed an unplanned biopsy on her vocal cords. that apparently caused her vocal cords to seize cutting off her air supply. the paper says this procedure should have been performed at a hospital, not a medical clinic. the new york state health department is investigating where the procedure was done. members of congress are putting pressure on the nfl to hand out tougher punishments for domestic violence. richard bloomenthal says the nfl needs stronger, stiffer rules to deter and punish domestic violence abusers. he's working on a proposal to force the nfl and other major sports leagues to address domestic violence more vigilantly. he says it could include cutting off financial benefits

such as the league's tax-exempt status. >> the nfl has really disgraced football in the sense that it has failed to treat sufficiently serious a brazen, brutal incident of assault. >> at first, the nfl suspended rice for two games but changed it to an indefinite knit suspension after the elevator video was made public. california fish and wildlife says dna tests show the mountain lion involved in sunday's attack on a 6-year-old was a male mountain lion. biologists are still searching for the cat. they set up traps baited with meat and two trackers and dogs are also on foot searching for the mountain lion. the 6-year-old boy who was attacked is recovering at home. when the mountain lion is found, it will be euthanized. it's becoming more and

difficult for san jose's homeless to encounter the jungle. there's a plan to put a gate at story road to act as a barrier. the city wants to eliminate illegal activity like dumping. hundreds of homeless live in the area. they will continue to allow outreach workers in to help those in need. the plan is drawing criticism for people who live in the encampment and from homeless advocates who help feed the homeless. a van that comes every tuesday to help the people who are homeless and who can make it to the doctor's office and things like that. there are resources that come here on a weekly basis. they help feed the homeless. >> the city says it would like to clear out the encampment there by the end of the year. if it feels like you have a lot more company on b.a.r.t. trains these days, you are right. b.a.r.t. saw a significant jump in b.a.r.t. ridership in august. 27,000 more people compared to the same time last year.

to make matters worse, more than 100 b.a.r.t. cars are out of service every day for maintenance and upgrades. we spoke to one commuter who says it's harder and harder to find a seat. >> as an older rider, i admit, as an older rider, you know, it kind of -- 40 minute ride from walnut creek to san francisco it impacts my health. if i have to stand for 40 minutes on a moving train, it hurts me. >> the problem is likely to get worse because ridership is expected to go up even more in the next couple of months. a b.a.r.t. spokeswoman said every available train is in service. californians are using less water but it still hey not be enough as the state deals with the third year of a cripping doubt. water agencies are reporting a 7.5% drop in monthly water use in july compared to a year ago. governor brown declared a drought emergency in january and called on californians to cut water use by 20%.

statewide restrictions include fines up to $500 a day for water wasters. the state waterboard could consider even more aggressive conservation measures later this month. well, good wednesday afternoon. we're taking a live look outside looking out towards oakland. a lot of haze out there. some of the smoke drifting in from the fires across the state, the fire in yosemite. but also the big one up towards the happy camp complex near the border with oregon. that's over 100,000 acres. some of that haze is approaching the bay area. it will be a factor in the forecast for today and over the next few days. an area of high pressure is setting up shop that will cap the haze in the bay area. at least right now, we have mostly clear skies except some fog. still hugging parts of the shore line. here is a closer look at the satellite showing you that fog bank. up and down the coast from mendocino county down toward santa cruz as well. the few patches of some

clearing closer to monterey bay. it's warming up out there. san francisco right now checking in, 73 degrees. long at the 8 -- look at the 80s out towards concord and walnut creek. that's the headline today. we're tracking 90s in the forecast. for today, hazy sunshine. and warmer. here's another camera looking out toward the bay from our transamerica pyramid in san francisco. tomorrow, mostly sunny skies. hot inland. for the weekend, it will be warm to hot. we'll shave off a few degrees in the second half of the weekend by sunday. for today, though, we'll have patchy coastal fog. hazy sunshine. temperatures up a good 3 to 6 degrees over yesterday's readings. the trend will continue for thursday, friday, saturday especially by friday. warmest locations inland could be in the upper 90s around possibly 95, 96, 97 degrees. with that heat, this time of year, fire danger, a big concern. that will be going up across the entire state. that does include the bay area. so that we don't have any

warnings in place but something we'll be watching over the next -- at least the next two, three days. forecast highs, santa rosa, 87 degrees. san francisco beautiful, especially downtown in the 70s. 76 brentwood. 93. you will see some 90s out towards pleasanton and livermore. san jose 82. here is a look ahead to the five-day forecast -- the warming will continue with increasing fire danger, thursday, friday. saturday will be the hottest day of the weekend, not by much. we'll shave off a few degrees. maybe one or two. these are minor changes. this is the time of year the bay area heats up and pretty much right on schedule. i will keep an eye on the fire danger. >> kind of that indian summer -- >> yeah. the mornings are pretty chilly. but the afternoons you notice the warmup. mayor ed lee helped kick off the return of fleet week with a few announcements. he gathered at the marines

memorial club library on sutter to introduce the event. it was canceled last year due to budget cuts. it begins on thursday, october 9th, and will include activities and performances for the public along with a chance for a local agency to conduct emergency drills with the military. >> it's our police and fire, our port, our recreation and parks departments. all of the various agencies have a very unique opportunity to practice what i think is most challenging in a major disaster. that's logistics. >> the blue angems will also return to -- angels will return and the parade of ships which are two of the major attractions for an event that often draws a million spectators. as we reported to you yesterday, apple's new iphone is about to hit the market. already one wireless service carrier is offering a deal for you to get the new device for free. but there is a catch.
