Forecasters said heavy downpours will move north east across the region on Thursday evening and into the early hours of Friday, accompanied in places by strong and gusty winds.
All counties are affected by the warning, however western areas are said to be "most at risk".
The Met Office added: "The public should be aware of the risk of minor disruption to travel through the combination of locally heavy rain and gusty winds."
The warning is valid from 6pm on Thursday.
It is expected that some locations will see bands of heavy rain bringing up to 30mm of water in a period of three to six hours, mostly in the west of Northern Ireland.
The chief forecaster said: "A deep depression is moving slowly northeast to pass to the north of NI early on Friday. Bands of heavy rain moving around the depression in unstable air will move across NI bringing 20 to 30mm of rain in three to six hours to some locations, chiefly in the west.
"Blustery winds may accompany the rain with gusts of 40-50 mph possible in exposed spots".
