00:00Hello. Welcome to your weekend update from the Met Office.
00:03Another weekend where we're talking about a storm.
00:05Last weekend, it was Storm Kira.
00:07This weekend, Storm Dennis arrives.
00:10It's similar to Storm Kira in some ways,
00:12but there are important differences.
00:14The main one being that the winds associated with Storm
00:17Dennis are expected to be a little bit less than those
00:21from Storm Kira.
00:22However, Storm Dennis is likely to bring
00:25more widespread heavy rainfall and therefore
00:28a greater risk of further flooding.
00:31Now, again, Storm Dennis is an area of low pressure,
00:34which, like Storm Kira, is developing way out
00:37of the eastern seaboard of the United States,
00:40intensifying during Friday as it crosses the Atlantic.
00:44The ice is squeezing together, so yes, it will be windy.
00:47But a slight difference track of Dennis
00:49as it pushes a bit further north will
00:51allow warmer air to push up across parts of the south.
00:54And that's crucial because warmer air
00:57brings more moisture with it.
00:58And that is one of the reasons why the rainfall with Dennis
01:01is likely to be heavier more widely across the UK.
01:04And that's why there's a greater risk of more widespread
01:07flooding from Dennis.
01:08Having said that, it will still be a very windy weekend.
01:11We start off with patchy rain across parts of the south.
01:15And then this band of heavy rain tracks into Scotland
01:18and Northern Ireland.
01:19Parts of northeast England may not see too much rain
01:21until Saturday afternoon.
01:23But look at this.
01:24By the end of Saturday, much of the UK
01:26will be experiencing heavy rain and strong and gusty winds.
01:31Those winds likely to reach 50 miles an hour inland,
01:3360 to 70 miles an hour around coast.
01:35So again, a notch down from Keir at last weekend,
01:38but still with the potential to cause damage and disruption.
01:43It is milder air, so temperatures
01:44likely to get into double digits,
01:46maybe even into the teens.
01:47But of course, it won't feel all that pleasant.
01:50Storm Dennis then hangs around through Saturday night
01:53into Sunday.
01:54Again, a lot of isobars on the chart.
01:55This weather front pushes southwards, bringing rain.
01:58And then it kind of wriggles and ripples.
02:00And it's this waving weather front
02:02that continues to bring rain across parts of the south.
02:05So again, that is why we're particularly
02:07concerned about rainfall amounts really starting to build up
02:10through the weekend.
02:12Just look across the south.
02:13It is a very soggy Sunday indeed.
02:15Further north, it may turn a bit drier and brighter.
02:18But there'll still be a lot of showers packing in.
02:20And still windy.
02:21And again, after Storm Keir and after what
02:24has been a very lively week of weather,
02:26trees and structures may well have been weakened.
02:29So although the winds may not be quite as strong as Keir,
02:31they could still cause damage and disruption.
02:34Temperature wise, again, on Sunday across the south,
02:37it will technically be quite mild,
02:38with highs perhaps getting into the teens, that milder air
02:42that Dennis is bringing.
02:43Further north, though, it will be turning a little bit cooler,
02:46but perhaps not quite as wet on Sunday,
02:48with some brighter spells in between those showers.
02:52So just a reminder, there are warnings in force
02:54for Storm Dennis this weekend.
02:55Amber warnings for rainfall.
02:57And many yellow warnings for both wind and rain.
03:01Please make sure you stay up to date.
