High tide has passed in Cork without further flooding and water levels on the River Lee have begun to drop.
The situation is expected to continue to improve throughout the day, with mainly dry weather forecast.
Several streets in the city centre were flooded last night, with water entering a number of business premises.
Of the three high tides since Tuesday night, last night's caused the most flooding, with higher water levels extending even further through the city.
Water covered all of the South Mall, while nearby Oliver Plunkett Street also flooded last night, for the first time this week.
Water entered a number of premises on both streets, although damage was minimal.
Cork City Fire Service has set up an operations room at the city fire station.
Last night 30 fire-fighters were operating on level two, the service's response to localised flooding.
