The Met Office has warned the heavy and persistent rain could lead to some disruption to travel.
In Lisburn, there are reports of heavy flooding on the A26 Glenavy Road between Glenavy and Ballinderry, the M1 motorway and Nutts Corner Roundabout.
This is causing both long delays and dangerous driving conditions.
Motorists are urged to approach the area with caution.
Those heading for the Belfast International Airport may wish to choose an alternative route to avoid unnecessary delays.
PSNI have advised motorists that the following roads in Londonderry are affected by flooding; Victoria Road, Bready, Ardlough Road, Trench Road and Woodside Road.
One resident contacted UTV to describe flood waters rising at the back of his house in Hamiltonsbawn in Co Armagh as nearby drains are unable to cope.
The rain is forecast to die down later and drier and brighter conditions will follow from the west, reaching Belfast into the evening.
It will be dry for most of the night but a few showers will affect the north coast.
A few sunny spells and showers are expected on Friday.
