UK Storm Dumps a Month of Rain in a Day

September 25, 2012; 8:45 AM ET

A major storm that ushered in the fall has lashed the U.K. with flooding rain and high winds.

At least four deaths were attributed to storm-related incidents, the Daily Mail website said on Tuesday.

Homes flooded and/or evacuated numbered in the hundreds, according to the Daily Mail and other U.K. online media, as hundreds of official flood warnings and alerts covered the land.

A number of people stranded by flooding had to be rescued.

Roads were submerged, hitting traffic flow. Rail transport suffered disruption.

The storm's gales at sea whipped up high surf along the North Sea coast. Online images of coastal Scotland showed landscapes literally awash in sea foam churned by the waves, then blown ashore by the strong winds.

Torrential rain began Sunday night in the south and west, then spread through northern England to parts of Scotland and Ireland Monday and Monday night.

The highest rainfall since Sunday, 108 mm (4.3 inches), was collected at Ravensworth, North Yorkshire, the U.K. Met Office said. The site has a normal September rainfall of only 47 mm (1.9 inches).

Antrim, Northern Ireland, had 98 mm (3.9 inches), the Met Office said.

Data accessed by AccuWeather.com showed rainfall of 85 mm (3.3 inches) at Rhyl, Wales. Crosby, Merseyside, had 79 mm (3.1) inches.

While the Met Office, through its online blog, dismissed claims that the powerful storm was actually the remnant of the former Hurricane Nadine, it did allow that heat and moisture from the tropical cyclone could have given a boost to the U.K. storm.

Saying that the storm had a lowest pressure of at least 973 mb, the Met Office called the low "unusually deep for September. The last time a pressure this low was measured in September was in 1981, they said.

Tuesday, deep low pressure at the center of the storm was over the Irish Sea, with rain spread across the width of the British archipelago.

This weather system, still capable of giving heavy rain, was forecast to remain strong through Tuesday night as it drifted south to Wales, then was to weaken while leaving southwestern England for France at midweek.
