it going to be sticking around? for the answer we know who to go to, nbc 10 chief meteorologist glenn "hurricane" schwartz. >> it's not going to last much longer, certainly not going to last all night. it's already tapering off. visibility is getting better around the philadelphia area as the rain gets lighter. you can see the heaviest of the rain moving through burlington county into ocean county. we still have rain covering a good bit of the area. most of it is on the light side now. especially compared to what we saw a couple of hours ago you can see the yellows and the oranges moving away and in some places very invest light rain or no rain at all. that is the first time we've seen that in a couple of hours. as we look at the wider view we see where the heavy rain is moving. ocean county about to get it, and the back edge of it not too far away out by harrisburg. so it's a matter of a couple of hours before it is over. the temperatures knocked down by the rain as well as 41 in pottstown. still way above the freezing point, don't have to worry about any change to snow or anything before it ends. because it's going to be ending, moving out fairly quickly by 7, 8:00 it's even

has been poring over this report. >> in the documents are interviews and some of the mechanical findings from the locomotive, what it doesn't say, though, is name a cause or assign blame. hundreds were hurt and eight died when amtrak 188 bound for new york flew off the track at 106 miles per hour, in his first interview days after the crash, engineer brandon bostian told investigators quote the last memory i have is approaching and passing the platforms in north philadelphia. i remember turning on the bell and the next thing that i remember is when i came to my senses i was standing up in the locomotive cab after the accident. in separate interviews his co-workers described him as professional, and loving his job. after the crash bostian described going to the hospital in a police van with other crash survivors, in his second interview six months after the derailment he provided more detail but said he didn't know how the train accelerated to 106 miles per hour. he said, quote, my practice is to i gradually then the throttle. i don't slam it open when i'm going slow. he told investigators he remembers traveling 70 miles per hour on a straight stretch of track shortly before the curve. dr. allen ziremski says finding out what happened next is key. >> it takes time and takes acceleration. and it takes a significant amount of acceleration. each an engine as powerful as the train it still takes a significant amount to go from 70 to 106 miles an hour. >> bostian told investigators one of his earliest memories take his cell phone out and calling 911. there have been questions about what bostian was doing in the moments leading up to the crash, whether he was distracted. he didtell investigators he was both sober and got enough sleep the night before. >> more

too much lead after the city tried to save money by switching water sources. the situation there has some people here wondering if the same thing could happen in their community. nbc 10's delaware reporter tim furlong is looking into how you know your water department is doing what it's supposed to do. >> reporter: building up muscles, they are also helping others. these women post add request on social media, they needed botted water and supplies for flint, michigan, they are doing the sprint to flint road trip with a donation on tuesday. >> we want to make sure that the people who need the supplies, the elderly, the kids, are getting the supplies that they need in the neighborhood. >> reporter: when the city of flint switched to a cheaper supply they switched to a less healthy one. the state reportedly broke the law by not treating the watt wer a cheap chemical that could have protected families. the water is now unsafe. residents develop rashes and the future effects for children exposed is uncertain. you see this, the water company brings this to thousands. they have a command center monitoring pressure and quality and they are constantly checking the water in their lab to make sure it is safe. artesian says nation wide our drinking water is generally pretty safe but say when that water gets into our homes pipes and faucets that's where lead can leech into the h 2o. most water companies treat water with a corrosion inhibitor. that didn't happen in flint. >> before you use it let it run for a minute or so. that allows that initial bit to come through and avoid an issue such as any lead that may have leeched in overnight in your plumbing. >> you should also check your water company's quality report and call your local or state health department if you have concerns about quality or safety or need professional water testing. it's great to see delawareans going out to help people in flint. we hope we never have a problem here like they do there. tim

we set up for somewhat cooler weather tomorrow. we've got that rainy rush, we have record warmth coming in on wednesday and heavy rain as well. leading to a flood watch for much of the area as you'll see. we have improving conditions across philadelphia area. it's 50 degrees now but the rain is getting much lighter, the wind is very light. only 3 miles an hour. and as you can see visibility is good, the temperature gradually going down overnight but staying above the freezing mark in the city. and so we're not going to get any kind of freeze over there. in the northern and western suburbs, there may be patchy areas of ice tomorrow morning. it's going to take a while for the temperature to get down. 41 in pottstown and in mount pocono. those are the cold spots. 53 in atlantic city is the warm spot. and we did have some places up to 60 today. and much of the area has a flood watch. now for the rain that happened this afternoon but for wednesday and into thursday, it's combination of the heavy rain plus the warm temperature melting the snow plus the high humidity melting snow when you combine that moisture it may be enough to cause some of the creeks and rivers to go up. so something will have to be watched. you can see the general area moving through, really never really reaching the poconos. which is fine with them to not get rain. they are going to get it wednesday. and patches of a little moderate rain left, but nothing like that heavier rain area that moved through and there are some areas without rain for once. there is a patch near broomall, king of prussia getting rain right now. and the back edge toward harrisburg, lighter and lighter as we head through the early evening. this is the next storm affecting us. it's also affecting the rockies and it's going to affect iowa, and they are going to be reporting from iowa tomorrow after the election with near blizzard conditions in parts of the state. in the meantime, our rain areas move out pretty quickly by 8, 9:00, it's pretty much gone. and once it's gone it's dry for the rest of the night. dry tomorrow, then on wednesday we start off in the morning very warm, the main area of rain comes in later in the day, possibly affecting the afternoon rush. and if it comes down that hard for a period of time with all of the melting snow, we could see some flooding as a result of that. we're also going to see some record warmth, philadelphia's record is 62 degrees on wednesday, predicting 66 and in southern delaware going for 70. beating the record by 7 degrees. for the rest of the night tonight, down to 34 in philadelphia, 28 in north and west, with clearing conditions late tonight. tomorrow, a lot of sunshine and light winds, temperatures about 10 degrees above average. a lot of people are going to love tomorrow. wednesday is going to be really warm but ending up really wet. and wednesday night too, very wet. dry out thursday, cool down, more on friday. and then go back up a little bit over the weekend. setting us up for a close call for a potential storm on monday. borderline rain snow. >> i'm john clark live in cherry hill new jersey where carli lloyd is being honored.
