in collapsed buildings. officials say it could take years for texas to recover from the storm. james cook reports from the city of corpus christi, close to where harvey made landfall. dan, are you in here? this is what a category four hurricane means in reality. dan? searching in the wreckage to find out if your neighbour is dead or alive. it seems that dan did get out, just in time. and then about 10:30 or so, it all quietened down, and i walked out and there's a tree in my yard and then becky's house is completely gone. the power of the wind is plain at the harbour where harvey made landfall.

just out to sea, 30 people in five vessel had to be rescued by helicopter. but these men, who live in their boats, battened down the hatches and rode it out. they are lucky to be alive. were you in your boat last night, during the storm? yes, he was, there, too. how was that? laugh. no... no brains! the power of the hurricane is all too clear when you look at the damage it caused these homes. this is a really poor neighbourhood and a lot of people here say they simply do not know how they will now rebuild their lives. this is what they endured through the night. 130 mph winds which left nearly 250,000 homes and businesses without power. it is still too early for a comprehensive assessment of the damage, but it will be costly. and the danger is not over yet. the storm is inching inland, dumping huge amounts of rain. our primary concern remains dramatic flooding. the state and various agencies

remain very active in the search and rescue process, and that will be one of the foremost tasks that we undertake in the coming days. the flooding has begun and the forecast is that it will get a lot worse. this disaster is still unfolding. james cook, bbc news, corpus christi, in texas. let's stay with hurricane harvey, then. bristel minsker is a spokesman for the american red cross and she is at a shelter in austin, texas — which is almost 350 kilometres away from corpus christi near to where the hurricane made landfall. she told me more about the situation there. the red cross is really preparing for the worst here in texas. this storm has been unlike a storm we have seen in years and years

in this state. the devastation on the gulf coast is just really shocking. and here inland at austin, texas, where i am, we're preparing for possible flooding and flash—flooding as the storm continues to brew over the state. and we have about 25 shelters open across the state of texas. more than 1,500 people stayed in those shelters last night, and that number is continuing to grow, as communities across the state are realising that their neighbourhoods are flooding, and they're going to be seeking shelter with the red cross. bristel, all those people that have come to stay with you, was that an organised response, or were those people who couldn't get far enough away? here in austin, most of those people have self—evacuated, so they took their vehicles from communities along the gulf coast and came to our hurricane evacuation centre. 0ther centres in texas have had buses that have evacuated from communities across the coast, that have come to those evacuation centres. there has really been a statewide effort to get people away from the coast, from the most

dangerous areas, and we're continuing to provide safe shelter, as the rain continues to fall for the next couple of days. bristel, how are those people doing? i imagine they are very worried for their homes that they have left. many people don't know the state of their homes. and that is, of course, very scary, to not know if your home is still standing, or what shape it's in. to not have heard from friends orfamily members, and you just want to know that everyone is ok. at the same time, folks i've talked to the shelter are incredibly hopeful, and they seem to maintain a positivity, even in the face of this incredibly scary situation. and red cross volunteers on the ground are just trying to make sure that they have a comfortable place to stay for the short term, a home away from home,

clears. yes, bristel, what is it looking like now? well, the rain is certainly falling here in austin, the rain has started falling, and it's been consistent all day. and that is pretty much true for most of south and east texas, all the way down to the ocean. we are expecting rain through monday. flash—flooding warnings are in effect. we're encouraging people to stay off the road and take safety precautions, because flooding could continue to happen. and this could be a historical event, and we just want people to stay safe. we're prioritising making sure that they have shelter to go to. we're ready to scale up and open more shelters as needed. if you want more on tropical storm harvey — don't forget you can stay up to date with the latest news on our website bbc.com/news. let's take a look at some of the other stories making the news.

the national trust says the increasing popularity of wild camping, where people pitch a tent away from organised areas, is threatening the beauty of the region. dave guest reports. wild camping is all about getting far away from civilisation, and far closer to nature. it's about going and spending a night high up on the hills, away from civilisation, often away from all the people, and spending that night sort of, you know, with nature, under the stars, in a very self—sufficient, sort of low—key manner. responsible wild campers such as these make sure they're discreet, they don't cause any damage, and they take everything home with them when they leave. so it has traditionally been something done on the higher hills. what is the change you have noticed recently? i think new audiences have become

aware of wild camping, but are treating it in a very different manner. there seems to be a bit more of a disposable culture, coming into what people perceive to be wild camping. and that now is very much coming generally within 500 metres of our car parks, carrying in as much stuff as they need. and, as for taking everything home, well, well, this is what national trust rangers are finding frequently in the lake district. ranger simon hill is spending more and more of his time chasing off and clearing up after the clueless campers. in this particular area, we have pulled out countless tents, inflatable mattresses, batteries... so this is evidence of the remains of a fire site. it's quite often the sort of remnants that we'll come across. i have to say, we've had experiences up here where we've taken trailer loads of rubbish out. of course, it has become common place for festival—goers to abandon cheap tents, sleeping bags and other camping clutter, at the end of a festival, knowing someone would clean it up. but this, of course,

is not a festival site. well, the national trust say they're not trying to stop all wild camping in its traditionalform. but they do want people to do it responsibly. so, if you want to know how to do that, visit the national trust website. dave guest, bbc news. a reminder of our top story. the remains of tropical storm harvey continued to lash texas. rescue effo rts continued to lash texas. rescue efforts have been hampered a strong winds. hundreds of thousands are without power. harvey began as a major hurricane, the first to make la ndfall major hurricane, the first to make landfall in the us in several years. stay with us on bbc news. goodbye for now. hello. if you approved of saturday's weather, then sunday shouldn't let's take a look at a couple of images from saturday. it was often cloudy,

but there were some warm, sunny spells coming through. most places stayed dry. there were just one or two isolated showers around. particularly across northern parts of the united kingdom. this finger of high pressure that has moved in across the uk will keep most places dry for part two of the weekend, during sunday. again, it won't be clear blue sky. in fact, from the cloud to begin with, there could just be a few spots of drizzle around north wales, north western england, and a lot of cloud feeding into scotland, northern ireland, and north—west england. elsewhere, the cloud will break and some sunny spells coming through. again, while most places will be dry, there is a weather system close to north—west scotland — the thickest cloud here, more breeze. some patchy outbreaks of rain, especially into south wales. and some spots into the mid—20s. we're looking fine at the test match at headingley. as that continues, there'll be some sunny spells coming through that cloud.

a bit more breeze, though, by the time we get to monday. for the notting hill carnival, glorious weather. temperatures head up even further by the time we get to the bank holiday. and the winds remain quite light. here is how it is looking through sunday evening, so if you're planning a barbecue, you're in good shape. but as we go through sunday night, you'll notice the rain starting to gather a bit more towards the north—west of the uk into northern scotland. some outbreaks of rain moving through. on towards the northern isles as well. the wind is picking up. these are overnight temperatures. and monday's big picture does look a little bit different. high pressure being squeezed away, weather fronts coming in. and they're poised to move their way southwards during monday into tuesday. now, what that means for monday is that we'll see for scotland and northern ireland, more cloud, stronger winds, and outbreaks of rain moving south. going into monday evening, some will be moving into northern england and north wales. whereas, to the south of that, it will continue notjust dry, but with plenty of sunshine. a range of weather on monday. a range of temperatures, as well,

from the breeze and the rain to where we see a break from the breeze in the rain to where we see the best of the sunshine, with some places reaching into the upper 20s, to nearly 30 celsius. as we look further ahead to tuesday and wednesday, we will take that cool and fresher air, and gradually filter that further southwards across the uk. that's how it is looking here for the next two days. there isn't a great deal of change in texas. even though harvey has been downgraded to a tropical storm, that's a wind classification, it's still producing prolific amounts of flooding rain, and will continue to do so for several more days to come, as an extremely dangerous situation continues in texas. this is bbc news. the headlines: the governor of the us state of texas, greg abbott, has said dramatic flooding is his primary concern as the rains from tropical storm harvey
