Storm Hannah is expected to hit the UK and Ireland this weekend, with forecasters predicting gusts of up to 80mph and temperatures "more like January".
The storm, whose name was announced by Irish weather service Met Eireann on Thursday, is expected to bring strong winds to Ireland and southern parts of the UK from Friday afternoon to Saturday morning.
Met Eireann has issued a status orange advisory for Clare, Cork, Kerry and Limerick from 4pm on Friday to 5am on Saturday, warning of the weather "becoming stormy on Friday evening and overnight as Storm Hannah moves in", bringing gusts of 110-130km/h (70-80mph).
The Met Office has also issued a yellow warning for winds in southern Wales and parts of the south and south-west of England, warning of gusts up to 70mph on coasts.
The warning is due to last from 9pm on Friday until 3pm on Saturday, with forecasters predicting "a risk of disruption to travel".
Storm Hannah - the fourth named storm in the UK and Ireland in 2019 after Erik, Freya and Gareth - will bring contrasting weather from the scorching Easter weekend.
Highs of 25C were recorded at Heathrow and Northolt in London on Bank Holiday Monday, making it the warmest Easter Monday on record in the UK and Ireland.
In contrast, this Saturday will bring highs of just 13C in the same areas, forecasters predicted.
Met Office meteorologist Alex Deakin said: "It will be such a shock when you compare it to last Saturday. Some places could be 15C lower than last Saturday. It's incredible, really.
"Some places through Saturday may be struggling in the single figures, while last Saturday we were in the mid 20s.
"It's going to be a much colder feel, and that's temperatures on the thermometer - when you add on the strength of the wind on Saturday, it's going to feel more like January at times, especially compared to last weekend when it felt like summer."
But Mr Deakin said that Sunday looks like a "half-decent day" weather-wise, saying: "It's particularly good news for people doing the London Marathon, because if it were on Saturday it would be a wash out, whereas Sunday looks a lot better."
