00:00 Hello, Storm Isha has been named by the Met Office as the weather takes a dramatic turn
00:06 for the unsettled this weekend. Now, we end Friday with high pressure across southern
00:11 parts of the UK. It was a cold but bright day, but westerly winds are starting to turn
00:16 up across the UK. They'll bring much milder conditions through the weekend, but they'll
00:21 also bring increasing spells of wet and very windy weather. And the Met Office are certainly
00:27 concerned about this system moving out of the states on Saturday and being picked up
00:32 by a straight line and powerful jet stream that will deepen this low. And as Storm Isha
00:38 approaches on Sunday, tightly packed isobars will bring widely strong and perhaps disruptive
00:44 or even damaging wind gusts. But there's also concern about the rain because we're going
00:48 to see a spell of rain move through north-western parts on Saturday, followed by further spells
00:53 of wet weather certainly during the second half of Sunday and into the start of Monday.
00:58 Now, that rain combined with snow melt could cause some real issues. We haven't had a long
01:04 enough dry spell to avoid the worst of the impacts from this wet weather. So, yellow
01:10 rain warnings in force for Sunday and into Monday. And mostly it's western hills that
01:15 will see the bulk of the wet weather, 50mm widely. And for some hills across Wales and
01:21 north-west England, there's the risk of 100mm of rain. And for northern hills certainly
01:27 we've got a lot of snow cover that is going to progressively melt through the weekend.
01:31 So, that's going to add to the wet weather. So, issues to do with rain, but then later
01:37 Sunday as well we've got the issues with the winds. It's already going to be windy as we
01:42 end Saturday. You can see wind gusts of 50, even 60 miles an hour across western coast.
01:47 That's Storm Eisha is going to turn up and bring another bout of very windy weather.
01:54 And it's the strongest winds will be on the southern flank of Eisha. Eisha will end up
02:00 close to the west of Scotland by the end of Sunday. Some uncertainty actually about the
02:04 west of Scotland because different computer models are handling the depth and the track
02:08 of this low slightly differently. That will make a big difference because western Scotland
02:12 will be close to the eye of the storm. But certainly a lot of agreement in much of the
02:17 computer model output on a wide swathe of very strong winds across England, Wales, southern
02:23 Scotland and northern Ireland. And as you can see the wind gusts graphic here at 9pm
02:27 on Sunday indicates widely inland 50 to 60 mile per hour wind gusts. And for some western
02:34 areas the risk of inland gusts of 70 miles an hour and perhaps 80 miles an hour for some
02:40 of these Irish Sea coasts perhaps. And then later on into the start of Monday strong sway
02:46 the winds pass close to the far south east. So yes another spell of very windy weather
02:51 in the south east. And so there are yellow warnings across most of the UK aside from
02:57 Shetland and amber warnings for those particularly windy spots. Now within the yellow warning
03:03 areas there's likely to be wind gusts of 50 or 60 miles an hour widely. A risk for some
03:09 exposed coasts of 70 miles an hour. But within the amber warning area there's the risk of
03:14 70 miles an hour inland and 80 miles an hour for some of the most exposed coasts. And that
03:20 would lead to some significant impacts. We're talking about damaging wind gusts, some tiles
03:24 blown off that sort of thing, travel disruptions. So although the worst of the winds go through
03:28 on Sunday evening into the early hours of Monday there could be trees down that could
03:33 affect people's routes as people get moving on Monday morning. Ferry crossings and airports
03:40 could also be affected. Dangerous coastal conditions so certainly take care if you're
03:45 heading to the coast on Sunday and into Monday morning. And stay across all weather warnings
03:51 and weather forecasts. We'll keep you updated right here at the Met Office. Bye bye.
