Bronagh, Deirdre and Saoirse: meet the storms blowing our way this winter
Ali will be the first storm to blow in across Ireland and Britain this winter, the new list of names for this year's strongest weather systems shows.
Also on the list of storm names for 2018/2019 announced by the Met Éireann and the British Met Office are Bronagh, Callum and Deirdre, while a particularly stormy winter could see storms Saoirse, Tristan, Violet and Wyn batter us.
It is the fourth year that Met Éireann and the Met Office have run the 'Name our Storms' scheme, which aims to raise awareness of severe weather before it hits.
The season's names have been compiled from a list of submissions by the public, choosing some of the most popular names and also selecting those that reflect the nations, culture and diversity of Ireland and the UK.
This year the first storm gets a male name, Ali, followed by an alternating pattern of female and male names which was established by the US National Hurricane Centre in the 1970s.
The alphabetical list of names skips Q, U, X, Y and Z to comply with international storm-naming conventions.
Derrick Ryall, head of public weather services at the Met Office, said: "Naming storms has been proved to raise awareness of severe weather in the UK, providing a consistent message to the public and crucially prompting people to take action to prevent harm to themselves or to their property."
Polling has found almost 80pc of people think giving storms a name is useful in making them aware the severe weather may have more impact than normal, while 63pc believe it is useful in letting them know to take action.
The 2017-2018 season kicked off with Storm Aileen, the first of 10 severe weather events to be named in the past year, and ended with Hector earlier this summer.
Evelyn Cusack, head of forecasting at Met Éireann, said: "The last 12 months have seen some extreme weather around the globe as well as here at home.
"While it is too early to say whether the coming winter will be a stormy one or a quiet one, we are prepared with a whole new set of 21 names for whatever nature may throw at us.
"As before, Met Éireann forecasters will work in close co-operation with our colleagues from the Met Office to keep all the peoples of these islands warned of impending severe weather."
