Flash-floods warning for Northern Ireland as torrential rain set to sweep in
A yellow weather warning is in place today as a storm is predicted to end a week of glorious weather.
Parts of Co Londonderry hit by widespread flooding last August are expected to be most affected with up to two inches (50mm) of rain within a few hours.
The Met Office's warning is for the whole of the province from 12pm, meaning people should be aware.
A forecaster said the west will bear the brunt of any storm.
She said: "There is a yellow warning in place from noon until 9pm for Saturday when there is a risk there could be slow-moving and thundery showers. Parts of Counties Derry and Fermanagh are most likely to see activity and this could spread into Co Antrim.
"Thunder and hail is likely, and there could be 20mm of rain falling within an hour.
"However, within three hours we could see 40 to 50mm of rainfall. There are areas that could continue to get excessive showers that could lead to a higher risk of some localised flooding, and perhaps 60mm.
"It is most likely to be western parts of Northern Ireland that these organised showers will happen, but depending on where you are on either side of that, it could be quite a nice day."
A yellow warning means there is a small chance that homes and businesses could be deluged quickly.
Parts of the north west were devastated by flash flooding last August.
In Eglinton and Drumahoe many business people and residents were knee-deep in floodwater after just 20 minutes of rainfall, but Derry and Strabane District Council is on standby should anyone need help.
It said: "Council is working closely with all relevant agencies to ensure the necessary support and assistance is available to anyone affected by flooding resulting from the yellow warning in place."
