Northern Ireland had the heaviest rain of anywhere in the UK yesterday with over a week’s worth falling in just one day.
At one point police issued a warning to motorists about surface water on the M2, urging them to slow down, use dipped headlights and keep a safe distance from the car in front.
A spokesman for Meteogroup, the Weather Forecast branch of Press Association, said rainfall in Northern Ireland was way above average.
“From 7am to 7pm there were some high levels of rain,” he said.
“In Ballypatrick Forest in Co Antrim 30mm of rain fell and across three other locations there was 25mm – Killylane in Co Antrim, Stormont Castle and Murlough in Co Down.
“This was by far the highest level of rainfall anywhere in the UK on Friday, with the next heaviest rainfall in Scotland at 11mm and Wales at 10mm.”
Last night, however, the heavy rain was forecast to move away and on to Scotland and northern England.
However, yesterday’s rainfall was certainly above average for one day’s rain in Northern Ireland for October, he said.
“The average rainfall for the month in Northern Ireland is 90-100mm, so 25-30mm means that just over a week’s rain fell in one day on Friday.”
“It was a heavy day’s rain and certainly above average for one day.”
The good news, however, is that the rest of the weekend is not projected to be just as wet.
“Saturday and Sunday will see scattered showers and the odd thunderstorm,” he said.
However, the reprieve is not to last.
“Monday and Tuesday will see very heavy rain once again and it will stay wet for much of next week.”
