Some parts of the Province received weeks’-worth of rain over a period of just 12 hours yesterday as the remnants of a hurricane struck the UK.
And as a drenched Northern Ireland last night prepared for another few days of showers, Rory McIlroy faced his own washout in America as rain delayed his US PGA Championship bid for almost an hour-and-a-half.
The Holywood sportsman faced a deluge at close to 1pm Kentucky time yesterday, while during early afternoon on the other side of the Atlantic the heavens opened over parts of Ulster too.
The east was particularly affected, and Co Down appeared to have been hardest hit of all.
Hurricane Bertha, a storm which has made its way east from the Caribbean, was being blamed for the unseasonable weather.
Formerly classed as a hurricane, the remnants of the storm brought gusty winds and lashings of rain to much of the UK as they swept over the British Isles.
Northern Ireland was subject to a yellow weather warning – but Met Office forecasters believe the worst is now over for the Province, and although there will be a wet and unsettled week ahead, it will not be on the same torrential scale as that seen yesterday.
According to the Met Office, the Province’s average monthly total of rainfall during August is between 80mm and 100mm.
However, the tiny village of Katesbridge – which stands on the River Bann to the north of Rathfriland – received 38mm between 4am and 4pm yesterday.
Over the same period, a weather station in Murlough received 29.8mm, and one in Killowen got 27.8mm.
However unlike last week, when there were reports of flooding in the west of the Province – especially Magherafelt – the Northern Ireland fire brigade received just one call-out to a report of flooding, occurring in Newry.
Forecaster John Mitchell for the Met Office said: “There will be heavy showers developing [on Monday], quite windy as well with a westerly wind.
“Through this week really, it’s going to be a fairly showery picture. It’ll be a bit on the cooler side across Northern Ireland this week as well.
“But we’re not expecting anything like the rainfall [of Sunday] at all.”
Across the rest of the UK the number of flood warnings climbed over the course of yesterday to reach 41 by 4.30pm.
Festivals were cancelled and sailings from Portsmouth to France were axed.
As travellers, revellers and homeowners in the UK struggled to cope, Rory himself – on the cusp of a major golfing victory – said he would tolerate a week’s worth of rain for a shot at his second PGA title, declaring: “It doesn’t bother me in the slightest.”
