Ali will be the first storm to blow in across Ireland and the UK this winter.
The list of names which will be used over the next year has been released by Met Eireann and Britain's Met Office.
Bronagh, Callum and Deidre are also featured.
After coming top of a Twitter poll by Met Eireann followers, Saoirse has also made the list.

This is the fourth year Met Éireann and the UK Met Office have jointly run the ‘Name our Storms’ scheme, aimed at raising awareness of severe weather before it hits.
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 new set of 21 names for whatever nature may throw at us", she said.
This year the first storm will be ‘male’ and named Ali, while the second storm will be ‘female’ and named Bronagh, following the alternating male/female pattern established by the US National Hurricane Center in the 1970’s.
When do we name storms?
A storm will be named for weather systems which we expect an Orange (Amber) or Red wind warning will be issued by Met Éireann and/or the Met Office.
This season’s names have once again been compiled from a list of suggestions submitted by the public, choosing some of the most popular names but also selecting names that reflect the culture and diversity of Ireland and Britain.
As in previous years, Q, U, X, Y and Z will not be used, to comply with the international storm naming conventions.
