The warning for the midlands comes into effect at 6am on Friday morning.
Storm Éowyn may pose a danger to life.
Met Eireann has upgraded its advisory to Red for Laois, Offaly and Westmeath from 6am on Friday until 12pm.
That means a risk to life, extremely dangerous travelling conditions, unsafe working conditions, widespread power outages, structural damage and wave overtopping.
Twenty one counties will be under a Red warning at various times on Friday.
Carlow Weather's Alan O'Reilly says the storm could be as bad as Storm Ophelia in 2017:
