Storm Brian is expected to hit Co.
Met Eireann claims Ireland will get very heavy rain and strong wind throughout today and tomorrow with western areas expected to bare the brunt of the storm.
Craig Snell, a forecaster for the Met Office, said: 'We have had the first effects of Storm Brian this morning and we will see gusts reaching 40 to 50 miles per hour winds in London in the second half of the afternoon.
"Explosive cyclogenesis" takes place when air is sucked upwards by the jet stream, leaving low pressure below.
"Strong to gale force gusts are forecast widely in the southern half of the British Isles, and gusts up to 70mph are possible in exposed coastal headlands".
The Met Office said the southern and western coast of England will remain under a yellow weather warning for wind until midnight on Saturday, when the worst of the storm is expected to have lost potency and moved into the far north-easterly reaches of Scotland.More news: Rumor: iPhone 8 Production Slashed in Half On Weak Demand

A Status Yellow wind warning has been issued for Co. Weatherquest forecaster Adam Dury said: "The weather bomb actually happened on Thursday night but we won't see the stormy conditions until the early hours of Saturday".
A weather warning is out for this weekend and the Environment Agency has issued a string of flood alerts. The Environment Agency's Alison Baptiste has warned the public to stay safe along the coast where there is set to be strong winds, large waves and some over-topping of coastal defences.
"We urge people to stay safe along the coast and warn against putting yourself in unnecessary danger by taking "storm selfies" or driving through flood water - just 30cm is enough to move your auto", she said.
The strong winds will also coincide with high tides "bringing the potential for unsafe waves", according to Met Office meteorologist Aiden McGivern.
Weather contingencies include the introduction of temporary speed restrictions due to high winds, which can blow trees and other debris onto railway lines and overhead power lines.
Despite Storm Aileen hitting the United Kingdom last month, and Ophelia earlier this week, Brian is the second, rather than third named storm of the year, as Ophelia was named as a hurricane.
