0:00:12 > 0:00:14Hello everyone, I'm Hayley.
0:00:14 > 0:00:19Welcome to Newsround on Tuesday afternoon.
0:00:19 > 0:00:23After 12 years with no major hurricane, America may end up having
0:00:23 > 0:00:25two in just a few weeks.
0:00:25 > 0:00:28Last month, Harvey hit Texas.
0:00:28 > 0:00:32Now Hurricane Irma is expected to arrive in Florida by the weekend.
0:00:32 > 0:00:37Look at this, a research plane flying directly through the storm.
0:00:37 > 0:00:40Phil Avery is our weather reporter and he's told us it's now
0:00:40 > 0:00:44a category five storm, the strongest there is.
0:00:44 > 0:00:48Over the past few days, I have kept a very close eye
0:00:48 > 0:00:51on Hurricane Irma as it's gradually worked its way through the Atlantic.
0:00:51 > 0:00:55Whilst it's been at sea, no big problems.
0:00:55 > 0:00:58But now it's much closer to all of these Islands and the eastern
0:00:58 > 0:01:00end of the Caribbean.
0:01:00 > 0:01:04The next couple of days I think it's going to move further to the west.
0:01:04 > 0:01:06By Wednesday, it will be very close to Puerto Rico.
0:01:06 > 0:01:14Then on Thursday, it will come very close to the north of both Haiti
0:01:14 > 0:01:17and also the Dominican Republic.
0:01:17 > 0:01:20Whilst it's close by, the hurricane will give winds of 150mph.
0:01:20 > 0:01:22There will be torrential rain so a lot of flooding.
0:01:22 > 0:01:24Some people will lose power and their phones,
0:01:24 > 0:01:29some may even lose their homes.
0:01:29 > 0:01:34Scientists think they've figured out why a big group of whales got
0:01:34 > 0:01:37stranded on Britain's coast last year and it's all to do with space.
0:01:37 > 0:01:40Ricky's got this one.
0:01:40 > 0:01:43They might look amazing but these solar storms caused a lot of trouble
0:01:43 > 0:01:47for a group of whales.
0:01:47 > 0:01:51Last year, 29 young whales were stranded on the coasts
0:01:51 > 0:01:58of northern Europe and nobody could work out why.
0:01:58 > 0:02:02But now scientists think it could have been down to large
0:02:02 > 0:02:05solar storms caused by the sun which are known
0:02:05 > 0:02:06as the Northern Lights.
0:02:06 > 0:02:09These storms in space could have affected the way the sperm whales
0:02:09 > 0:02:11navigate through the ocean.
0:02:11 > 0:02:16That's why they got lost in shallow waters and beached themselves.
0:02:16 > 0:02:20Beaching is when whales get struck on sand and can be very dangerous.
0:02:20 > 0:02:22It can happen for lots of different reasons.
0:02:22 > 0:02:25For these sperm whales it was down to the solar storms.
0:02:25 > 0:02:31But some whales become stranded because they're sick or injured
0:02:31 > 0:02:33and are pushed inshore by currents.
0:02:33 > 0:02:36It's thought changes in the environment could cause them
0:02:36 > 0:02:39to behave differently too, if food stocks are low,
0:02:39 > 0:02:42if temperatures are particularly high or low or if their environment
0:02:42 > 0:02:43has become polluted.
0:02:43 > 0:02:47Sometimes it's just down to mistakes.
0:02:47 > 0:02:50They can sometimes lose their way into shallow waters by accident
0:02:50 > 0:02:53whilst travelling to warmer waters to mate.
0:02:53 > 0:02:56Whales are very sociable creatures and often travel
0:02:56 > 0:03:00in large pods or groups.
0:03:00 > 0:03:07Marine scientists think that if one is affected by any of these things
0:03:07 > 0:03:09then others travelling with it will copy them, which
0:03:09 > 0:03:13could be what happened to the sperm whales last year.
0:03:13 > 0:03:16Some of you went back to school today, some are back tomorrow.
0:03:16 > 0:03:18Others started last month.
0:03:18 > 0:03:22Starting high school is one of the most exciting and most
0:03:22 > 0:03:28nerve-wracking times in our life so what's that actually like?
0:03:28 > 0:03:31Here's what our year sevens told our new starters.
0:03:31 > 0:03:34I think the school was a lot bigger than it actually is.
0:03:34 > 0:03:35Yeah.
0:03:35 > 0:03:37It's different, it's not the same as primary school
0:03:37 > 0:03:39and then moving school, it's just nervous.
0:03:39 > 0:03:42I found out I was going to a different high school
0:03:42 > 0:03:44than all any other friends, no one from my primary
0:03:44 > 0:03:47was coming to my high school so I was a bit nervous.
0:03:47 > 0:03:52In primary school, you're in the same sweaty classroom all day.
0:03:52 > 0:03:54As well, you never had food tech in primary school
0:03:54 > 0:03:56and I absolutely adore cooking food.
0:03:56 > 0:03:58I know how to make cakes and all that.
0:03:58 > 0:04:00It's like moving house because you're like you don't know
0:04:00 > 0:04:04and you have to make new friends, you have to leave old friends
0:04:04 > 0:04:07and sometimes you can still stay in contact but it's just a bit hard.
0:04:07 > 0:04:13I was scared I wouldn't make friends and once I made friends
0:04:13 > 0:04:14I was like going later.
0:04:14 > 0:04:17It's like huge and you think I am going to get lost,
0:04:17 > 0:04:19I don't know where I am going to go.
0:04:19 > 0:04:22Now I could probably find my way around with my eyes closed.
0:04:22 > 0:04:25Although I have made some more friends I really miss my other ones
0:04:25 > 0:04:27that didn't come with me.
0:04:27 > 0:04:31I don't know, just miss them.
0:04:31 > 0:04:36My brother and my two cousins were there.
0:04:36 > 0:04:39I knew that they would look after me.
0:04:39 > 0:04:42I knew some people but in primary we were really close.
0:04:42 > 0:04:45I was worried I wouldn't make friends but actually
0:04:45 > 0:04:46everyone's the same as you.
0:04:46 > 0:04:56They all know what you're thinking, so you're not on your own.
0:04:59 > 0:04:59That's
0:04:59 > 0:04:59That's some
0:04:59 > 0:04:59That's some amazing
0:04:59 > 0:05:01That's some amazing advice:.
0:05:01 > 0:05:02Thanks for watching.
0:05:02 > 0:05:03Newsround's back in the morning with me.
0:05:05 > 0:05:08Woody? What? All the kids are going back to school soon. Good.
