An amber warning will be in force from 3am tomorrow until midday, with up to 70mm of rain expected over higher ground.
Forecasters say it affects all areas, but river valleys along the east and northeast coasts are likely to see the heaviest rainfall.
Runoff could lead to flash floods, standing water and difficult driving conditions, particularly during rush hour tomorrow morning.
