A deluge at around 6.30pm yesterday led to a river of water rushing down fields onto the main Cork-Macroom road.
The water flowed in the back door of the Farran Well pub, and out the front door of the premises.
A neighbouring bungalow was also flooded.
Nearby, half of the garden wall in front of another house was knocked onto the road such was the ferocity of the flood.
The owner of that house, Neilus O’Connor, said: “I have never seen any rain like it. It was heavy for about 20 minutes.
“The water was careering down the fields and knocked about 25ft of the wall in front of my house.
“It was knocked onto the road so we then had to clear it off the road,” he added.
A drain near the Farran Well pub had to be unblocked after the rain ceased, to help alleviate the flood.
The roadway was barely passable as a result of the heavy rain.
The flash flood only affected an area of about half a mile in length, with nearby areas experiencing no rainfall at all.
Last night, neighbours rallied to the aid of those affected by the flood, getting involved in the clean up.
Last Saturday morning, a flash flood hit Grenagh and Blarney, cutting off local roads.
The weather was forecast to improve for today and tomorrow in most of the country.
However, the Cork area was forecast to have overcast conditions with high temperatures, with fog and mist from the sea.
There is further bad weather forecast for next week.
