Hello. Sometimes in weather, there are moments that take

0:00:030:00:05

your breath away. They came aplenty with Hurricane Harvey in Texas,

0:00:050:00:08

and they're coming again now with Hurricane Irma in the Caribbean.

0:00:080:00:12

This is just breathtaking.

0:00:120:00:14

This is a satellite picture from Wednesday of the eye

0:00:140:00:17

of Hurricane Irma passing directly over Barbuda.

0:00:170:00:20

Which means that Barbuda went from catastrophic winds one moment to

0:00:200:00:24

barely a breath of wind in the eye, and then catastrophic winds again.

0:00:240:00:27

Of course, Barbuda feeling the of full force of Irma,

0:00:270:00:30

as did St Martin, which also had landfall.

0:00:300:00:33

Now it's barrelling towards Puerto Rico during Thursday.

0:00:330:00:36

Watch out, north coast Dominican Republic, Haiti, and then

0:00:360:00:39

onto the Turks and Caicos Islands, Cuba and eventually Florida.

0:00:390:00:42

Though there's still some uncertainty about that.

0:00:420:00:45

And whilst Irma is not now having a direct impact

0:00:450:00:48

on our weather, what happens with Irma after Florida,

0:00:480:00:50

as remnants feed out into the Atlantic,

0:00:500:00:52

does bring us some uncertainty in our longer-range forecast,

0:00:520:00:56

as we'll see in just a moment.

0:00:560:00:58

But let's get back to our weather and how that's

0:00:580:01:00

developing during Thursday.

0:01:000:01:02

Of course, it's a much quieter affair, though there is a

0:01:020:01:04

weather system coming in from the Atlantic, initially bringing some

0:01:040:01:08

rain at the start of the day to northwest Scotland.

0:01:080:01:10

Quite heavy here, quite windy with that.

0:01:100:01:12

But the rain is on the move southeast during the day

0:01:120:01:15

across the rest of Scotland, Northern Ireland,

0:01:150:01:17

to Wales and western England.

0:01:170:01:18

Eastern parts of England, with the exception of the odd shower,

0:01:180:01:21

stay driest for longest, but even here, getting into the evening,

0:01:210:01:24

there should be outbreaks of rain moving in.

0:01:240:01:26

Those temperatures clearly suppressed where you've got

0:01:260:01:29

the heaviest rain and the strongest winds.

0:01:290:01:31

Eventually, we see some outbreaks of rain reaching down towards

0:01:310:01:34

southeastern parts of Britain as we go through Thursday and Friday.

0:01:340:01:37

But this weather front comes a player in the weather

0:01:370:01:41

across South wales, southern England on Friday.

0:01:410:01:43

Still something to play for in the detail,

0:01:430:01:45

but some spots could have quite a bit of rain all day long here.

0:01:450:01:48

Elsewhere, some sunny spells, heavy showers to be had.

0:01:480:01:50

Catch one of those, they could be thundery, perhaps with some hail.

0:01:500:01:54

Now that front does clear away,

0:01:540:01:56

but still low-pressure nearby as we look at the picture for Saturday.

0:01:560:01:58

Strong winds to the south and west of the UK,

0:01:580:02:00

lighter winds further east. Then a case of showers breaking out again.

0:02:000:02:04

So some drier, sunnier moments, but some heavier showers to be had

0:02:040:02:09

and still on the cool side.

0:02:090:02:10

Though if you find some sunshine, may not feel too bad.

0:02:100:02:13

Cool night to come, Saturday night into Sunday,

0:02:130:02:15

a little ridge of high pressure, a gap between weather systems,

0:02:150:02:18

but that gap isn't very big, because here comes another on Sunday.

0:02:180:02:22

So again beginning to spread rain southeastwards across the UK

0:02:220:02:25

and with this, the winds picking up as well.

0:02:250:02:28

Particularly down towards the South and South West,

0:02:280:02:30

from Sunday into Monday.

0:02:300:02:32

Around this deep area of low pressure, the isobars squeezed.

0:02:320:02:35

This could be a troublemaker, Sunday into Monday.

0:02:350:02:38

And again, where those isobars are close together, across the South

0:02:380:02:41

and South West, a risk of gales, perhaps severe gales in places,

0:02:410:02:44

so could be some impact from this.

0:02:440:02:46

Lighter winds further towards the North East,

0:02:460:02:48

showers around again, and some heavy ones to be had.

0:02:480:02:51

Going into Tuesday, that low trying to move away.

0:02:510:02:54

Still in a breezy, cool flow of weather.

0:02:540:02:56

But looks like a ridge of high pressure's trying to come in,

0:02:560:02:59

but there are more weather systems to come next week.

0:02:590:03:01

The bulk of next week is looking changeable and unsettled.

0:03:010:03:04

But by the end of the week and into the following weekend,

0:03:040:03:08

it looks like high pressure will try to establish itself in the Atlantic.

0:03:080:03:11

That would disrupt the flow of weather, given us

0:03:110:03:14

perhaps longer settled spells in between weather systems.

0:03:140:03:17

But a word of caution,

0:03:170:03:19

the computer forecasts are not yet taking into account what's

0:03:190:03:22

left of Irma and Jose, which has followed on behind Irma,

0:03:220:03:26

and how that's going to feed into to the weather across the Atlantic.

0:03:260:03:28

So it is a very big "watch this space".

0:03:280:03:31

You want to get rid of me.
