welcome back to "cnn newsroom". >> i'm rosemary church. we want to welcome our viewers in the united states and around the world. more than 300 angry relatives of passengers from flight 370 are demonstrating outside of the malaysian embassy in beijing. >> they are frustrated over the search effort and the lack of information coming from malaysia. >> winds and rain kept flights grounded on monday. the search is not likely to resume until wednesday, weather permitting. >> to announcements appeared to have ended all hope of finding survivors. the missing plane crashed somewhere in the southern indian ocean. >> the head of the airlines said the aircraft is now lost is no one survived. at a news conference he explained why he came to that

conclusion. listen. >> i think that's very accurate. also, especially last night. they came out and said that he fairly credible lead that would point to where the plane ended its flight. and the position is very remote away from the nearest land mass and after 17 days, we could only bring ourselves to reach the conclusion. >> malaysian airline officials faced pretty tough questions from reporters at the news conference. they didn't have a lot of answers. there was an explanation in part as to why they used the text

message to contact relatives of the passengers telling them the plane had crashed. >> reporter: yeah, this is something that cnn reported last night when we confirmed with some of those loved ones of passengers on board that they received information about the flight ending in the southern indian ocean as the prime minister put it in his first press conference by text message. the ceo of malaysian airline said this sole and only motivation behind the was to ensure that all of those loved ones, all those on board of mh 370 received the news before the rest of the world did, as pe hut it. they had more than 1,000 family members to take care of and talk to and think about in this event and tragedy. where they could try to speak to people personally and other

times they just decided that as a last resort they had to send out a mass text message. john. >> china is livid. the family says there's a cover-up, but beijing is asking for malaysia to hand over whatever information they have to prove this plane has gone down in the southern indian ocean. i know they want the satellite imagery. what else are they asking if and are the malaysians going to hand it over? >> reporter: there's a lot of anger, particularly amongst chinese families. 153 passengers from china on board that flight. there's been missing without trace. let's not forget we haven't had any kind of identification of debris connected to flight mh 370 from the search. still a lot of angst, a lot of

disbelief and anger as well. malaysian airlines are saying in the press conference here today that they are doing their best to take care of the families. here is what they had to say. >> we disposed it with to ensure that we remain what we say and reenable them to provide whatever search reach that we can do. we appreciate that. >> reporter: a lot of families have been here and in beijing waiting for information for 18

days now. nothing can compensate the loss of a loved ones, mothers, brothers, sisters, fathers. we have been speaking to some of those family members. one of them the father of aviation engineer on board who is still in denial. he's in shock about this news. he's not accepting quite yet that this is really happened. another family member says they have been told to be on stand by if and when malaysia airlines does find any kind of debris or information related to flight mh 370 they will be flown to the location. >> there's still no hard evidence, at least that's how it looks from this point of view. thank you so much for that. saima live for us there. >> the bad weather that put the air and sea search on hold will

also slow down efforts to retreat those two objects spotted in the southern indian ocean on monday. one is a gray or green circular object and the other is an orange rectangular object. it's not clear whether they are parts from the plane. the debris is the latest in a series of satellite or visual sightings. let's get to the search operation now. strong winds grounded the search plane on monday. we turn to andrew stephens who is live on perth with more on what's happening today. there were great expectations when everybody heard australia's defense minister was coming to talk to the assembled media there but not a lot disclosed and no mention of those objects and what came of that. that's right. there was an expectation here

among the press core that after the announcement from the malaysian prime minister yesterday that mh 370 crashed. we were expecting the minister to add detail about those pieces of debris that you just mentioned. they were spotted by the royal air force yesterday. a ship was sent to that area. to give you an idea how difficult this search remain, the defense minister said we are close to that area where that debris was spotted. those two pieces of great interest.

if you want a better example, this is what the vice head of the australian defense forces had to say about the search so far. it's to put it in context. >> it's a multinational effort going on. it is difficult in these weather conditions to be able to find small bits of debris that is washing around. they're still looking for the hay stack.

they don't know the area of the search. the needle is the wreckage. at the moment they still have a big chunk of sea. they do have promising leads as we have been speaking about. it's not only what the royal australian air force but what the chinese saw. experts are saying that sounds like it could be a debris not that far from where the australian's saw there. there's the tip of the spear of the focus. still with this weather, it's going to make things more difficult. the defense minister describing the conditions over the zone as horrendous. he was talking about ways, perhaps 20 to 30 meters high. even the australian navy ship which is in that area which got relatively close to the area where they found these, where they spotted these spepieces of

debris to leave the search zone. >> this is the frustration. we're seeing the images but once they get there it's difficult to locate them. they haven't at this point. the problem will constantly be this weather. it will get increasingly bad. >> reporter: we are told the weather should be clear enough to resume search by wednesday. you're right. it is frustrating. you can feel for the families of those passengers. you can understand why they are asking for proof. at this moment there is no proof. all we have is the british satellite company saying that is the area and they obviously have enough data to say without a strong degree of certainty that is where the plane went down. until we get a physical sign that shows this was indeed a

piece of the aircraft, we can then say it's crashed in this part. they start doing the modelling on the current, on the winds, on the wave action and trace it back from there. it's still a long way to go. i suspect we're in for many more frustrations. after they dropped flares near that zone it would be a relatively simple task for the australian navy to follow up those flares and pick up the wrecka wreckage. they were on site for about four hours yesterday and they didn't find it. it gives you an idea of the frustration that the families are feeling to no proof and the searchers as well. the pilots really want to get this mission completed. they want success. they need to be able to say yes we did our job. we located and we identified

that debris and then move on from there to the search. they're looking for the flight recorder beacons. we've got to remember we're returning out of time. 13, 14, days, minimum, 16, 17 days maximum before the pings run down and make the search more difficult. >> they've got to shrink their search. andrew stephens reporting. many thanks to you. >> even if they find the black boxes they may not be operating. >> the main thing is the recording box is not going to have a lot of material that they made at this point. >> malaysian's prime minister talked about news data coming from the british company as the satellite communications firm.

>> he said they were able to do something that's never been done before. they figured out the plane's direction of travel by using a particular calculation to analyze the jet's automated satellite data. a formman walked us through how they did it. >> what this search is coming down to is basic mathematic detective work. if you were to shout out to a canyon wall somewhere and wait for the echo to come back, it would take a certain amount of time. if the wall were further away, it would take longer. you combine that with the doppler affect and that's how we got this arc of where the plane might be. they have this satellite in geostationary orbit. it's at the same spot above earth. we moved it into particular position so we can see it. 22,000 miles up. it's every hour sending a ping or electronic handshake down to

see where this plane is. if it's cloeser, it would be in one of the tighter rings. if it's further out it would be in the outer rings. they were able to establish the plane moved through the rings in this fashion. why do they think it didn't go to the north? there's a lot of radar up there in different cities and towns and they probably would have seen it up there but also the shape of the earth is not exactly round. you get a slightly different mathematical equation if you go that way as compared to the south. they checked this equation against existing planes. planes that they knew were out through and they specifically knew the location of. it's sort of like fast break if test problem in a rrithmetic an you have the answers.

they ran this equation and said it's right there somewhere in that region. that's allowed them to cut a gigantic search area down into something much more manageable and promising. >> we'll take a short break. w when we come back we know the search zone is narrowing. >> we'll show you some of the technology being used to find the missing plane. latte or au lait? sunny or bubbly? cozy or cool?

coming up 18 minutes past 2:00 on a tuesday morning on the east coast of the united states. we'll like to welcome back our viewers from the u.s. and around the world. >> we want to take a look to help find that missing malaysian airline flight. >> we see how information gleaned from an earlier crash may help them location flight 370. >> reporter: since the search began just the u.s. navy aircraft ha covered more than 360,000 square nautical mile pps. >> we know we're only looking in one hay stack whether than multiple hay stacks. >> reporter: search maps were developed to help location air france in the atlantic ocean. he took us through the sophisticated model they used. first a grid that showed where

it could have hit. where the debris would have fallen if the plane had a catastrophic failure at cruisiig altitude. >> if you loi layer those you get a heat map. it's probably in that location where it's red and green is a medium chance. >> reporter: managing those zones has huge obstacles. why is it search aircraft can promise so many leads and surface vessels can't find them. >> the item could have sunk. it could have been blown completely off on a different course or pushed someplace else and the ship will never find it again. >> reporter: china's government released this photo of an object that turned tout be a whale car

k c carcass. >> over a two week time frame they were checked to see where they were reporting. you see the buoy down here. the red dot started here and went west and ended up over in this region. >> reporter: one map grid a calculated as if the recorder pings were working. could those methods work for flight 370. this method could work in the indian ocean but without actual wreckage found it's tougher. he says they can't come up with data that's as clean or pinpointed a location as the air france maps did. >> the key here is the rough weather in the southern indian ocean making that search for flight 370 extremely difficult. >> so difficult it's on hold until wednesday.

that's about another 18 thundershowers before they get the planes back up in the air. what is the forecast? what can they expect in the coming days? >> the forecast goes downhill for the next eight to ten hours. we see a bit of an improvement from wednesday morning and back downhill again on wednesday night into thursday. the culprit right here. measure this front. this cold front extends to some 5,000 kilometers. more than 3,000 miles from the northern fringe to the southern fringe. that's equivalent to expanding across the continental united states. we see cloud cover pushing into the region. we know ahead of a storm it's very little in the way of land masses. the swells upwards of 13 feet. some could get up as high as 19 to 20 feet. the images here one of low altitude flying aircraft as it was returning towards perth australia. we know visibility was dropping.

it's anywhere from 200 to 500 feet. the aircraft flies as low as 300 feet. we know it's not like this. 13 foot swells in this region. we know white foam begins to break off the top of the waves and begins to streak across the ocean and you get this foam that the entire ocean becomes white an in the direction of the wind. this is a scenario the all white in front of you will be all white. no purpose to be out there. makes it extremely dangerous for vessels and aircraft to be flying with such winds. models up to 90 kilometers per hour. a strong tropical storm pushing them out. looks what happens tomorrow afternoon. the winds begin to die down. 15 to 20 miles per hour generally speaking which is common for this time of year. as we head into thursday they pick right back up, up to 60 plus miles per hour again. looks like we get a brief break tomorrow and once again thursday

morning could be rough based on the model estimates with rain moving back in to the region. we see this as it takes place with weather coming in every couple of days at these latitudes. 36 million aircrafts. this is a maritime patrol. designed to fly as low as 300 feet. you get down to the surface when the waves are pushing some 20 feet above the surface and sea foam spraying up, no need for everyone to be out here. it puts everyone in danger. >> absolutely. they are doing everything they can to find some debris and link it back to the aircraft. it's a tough challenge. >> yeah. it will continue to be for quite some time. we are getting word that malaysia's prime minister told parliament he decided to make an official announcement on monday

because he didn't want to government to be seen as hiding information on purpose from the families of the missing. >> flthere's been a lot of accusation it hasn't been transparent. the prime minister said his statement was based on leads and the most conclusive information we have which shows the mh370 aircraft ended in the indian ocean and we express our deeping condolences to all those involved. >> critics would say the timing was a little off. why not wait for some solid evidence. that's why we have families grieving, distressed because they want the information. >> the data came from the satellite company in britain. they got that the day before. that's when they decided to make the announcement. >> it's a tough call. very difficult. >> we'll take a short break. another story we're covering,

the number of dead and missing has risen after a land slide in washington. >> the obstacles facing those rescue teams.

welcome back. u.s. president barack obama has signed a declaration for washington state after a weekend landslide. >> the death toll is at at least

14. more than 176 are unaccounted for. some of the missing on that list are most likely safe. >> my neighbor's house and they're neighbor's house has been taken out. it's collapsed on several of them. >> reporter: as you can see the land slide was truly massive devastating two towns north of seattle. it covered one square mile and was caused by ground water saturation due to heavy rains in the area over the past month. >> this is one of the biggest land slides i've seen. >> reporter: more than 100 people are unaccounted for this man, who is a plumber who was making a call. his daughter isn't giving up. >> we'd have to think he's somewhere and safe and they can't reach him now. >> reporter: there's a heartbreaking reality in the message. >> i'm very disappointed to tell

you we didn't find any science of survivors and we found no survivors today. >> reporter: authorities warn those upstream that flooding there is still a very real possibility. the new york time s reporting that u.s. president barack obama plans to propose a law to end the government's bulk collection of data on american's calling habits. phone companies, not the national security agency, would hold the information for their normal 18 month period. the nsa would need a court order to get that data. russia is shrugging off what is effectively its expulsion from the group of eight industrialized nations. >> at the hague on monday they said essential economic decisions are made by the group of 20 nations and russia is still part of that group. >> the u.s. and its allies are

threatening more measures if russian ramped up actions in the ukraine. >> reporter: president obama raised the stakes with vladmir putin that will kick russia out of the g-8 after an emergency meeting that lasted more than 90 minutes. they came out with a statement that condemned russia. the g-7 said there will be no summit in sochi, russia later in june. lit be held in brussels. president obama said this is part of the cost that he wants applied to russia for what happened in crimea. >> europe and america are united in our support of the yukranian government and its people. >> reporter: the troops gathered

on the ukranian boarder, the g-7 leaders agreed that further sanctions against russia would be applied perhaps against the energy and banking sectors of that country if moscow were to make a decision to go into eastern or southern ukraine. the peninsula is not lost. you are watching cnn newsroom live from the cnn center. still ahead, the fate of the missing airliner may no longer be a mystery, but exactly where it is, that remains a question. >> we'll see how data is used to getting search crews closer to finding the it. some loved ones marched to mala malaysia's embassy. we'll go there live. ocuvite has a unique formula
