There will also be widespread wintry showers on Monday and Tuesday, with some snowfall - especially in the west and north.
Met Éireann says some disruption to travel is possible, particularly over higher routes.
The wind warning is in effect until midday on Monday - the snow-ice alert is in place all day Monday and Tuesday.
This comes as thousands of homes and businesses are without power following strong winds from Storm Ciara overnight.
ESB Networks says it is working to repair faults as quickly as possible.
Met Éireann says the storm will produce very windy or stormy conditions - with heavy rain giving way to sunny spells and frequent squally showers.
Some of these will see hail and thunder.
Winds will be at their strongest this morning and early afternoon, with some severe gusts.

A combination of spring tides and high seas will result in a significant risk of coastal flooding - especially along western and northwestern coasts.
There will be some surface flooding also with highest temperatures 9 to 11 degrees.
This evening and tonight will also see stormy conditions returning to some Atlantic coasts.
