Britain is braced for a battering of strong winds this afternoon, with Storm Hannah potentially yielding up to 40mm of rain and making floods “likely”. The Met Office issued a yellow warning of rain for Northern Ireland until 3pm on Saturday, which read: “Heavy rain on Saturday may give some disruption for parts of Northern Ireland. Flooding of a few homes and businesses is likely. Spray and flooding on roads probably making journey times longer. Bus and train services probably affected with journey times taking longer.” The weather service also issued a yellow warning of winds for parts of England and Wales, which read: “A spell of strong winds is expected across southern and some central parts of the UK, bringing a risk of disruption.
“Some delays to road, rail, air and ferry transport are likely, with bus and train services affected. Delays for high-sided vehicles on exposed routes and bridges likely.
“Some short term loss of power and other services is possible due to fallen trees and branches. It’s likely that some coastal routes, sea fronts and coastal communities could be affected by spray and/or large waves.”
BBC weather presenter Helen Willetts said: “For England and Wales we get a real buffeting flow of winds heading their way eastwards. But into the afternoon they are likely to liven up again for Northern Ireland, south-west Scotland in across the Isle of Man.
“That’s all tied in with a slow moving area of rain which could yield an inch and a half of rain, potentially 40mm or so. Temperatures are really going to struggle underneath that rain band and in those winds.
“Scotland there will be some sunshine but some heavy showers elsewhere with some thunder. As I say those winds could escalate a little bit more for Northern Ireland, south-west Scotland and through the Isle of Man into the afternoon.
“They will remain strong to gale force in the south, if not severe gale on the coast. But overnight they do tend to ease and that’s because we have got this little ridge of high pressure moving in for Sunday.
“So Sunday does look like the quieter day of the weekend, but even on Sunday, even when the winds are easing ready for the marathon, pretty good conditions actually for the marathon because we keep a lot of cloud and we keep a northerly breeze.”
BBC weather host Matt Taylor forecast the strongest of the winds to hit southern and western areas, alongside a frosty start for Sunday morning.
He said: “Winds peaked through the night, 82mph in Aberdaron in north-west Wales, but as the winds strengths have peaked it could still be a very windy afternoon for some of you. A low pressure system, Storm Hannah, pushing out in towards the North Sea.
“So southern and western areas of that will continue to see the strongest of the winds, lighter winds to northeastern parts of England for the timbering, that will change later on and certainly across Scotland much lighter winds.
“Some slow moving, maybe heavy and thundery showers here, the odd shower but with more sunshine across southern counties of England and Wales.
“It’s going to be a colder night than last night, Northern Ireland for instance could be a touch of frost around into the start of a bright start to Sunday morning here.
“That’s because we have got a ridge of high pressure building in, this little bump on the isobars to the back edge of Storm Hannah, which becomes even less of a feature as it pulls away tomorrow.”
Monday will be mostly dry, with some rain across western areas and the best of the sun in the north.
Tuesday and Wednesday are predicted to be more cloudy, with persistent showers as an area of low pressure approaches Scotland.
