The UK’s Meteorological Office issued a rare red severe weather warning for parts of eastern Scotland with “exceptional rainfall” of up to 22cm forecast for today and tomorrow.
Police said the body of a 57-year-old woman had been recovered after she was swept into a river in the county of Angus yesterday afternoon.
A second person also died in Angus yesterday evening after a falling tree hit the van the 56-year-old was driving.
Officials in the southern Irish county of Cork, where hundreds of homes and businesses were flooded earlier in the week, described the deluge there as the worst in at least 30 years.
A community hospital for the elderly had to be evacuated in the town of Midleton, Cork, where the main street was up to 1.2m underwater.
As the storm hit Scotland today, Scottish leader Humza Yousaf warned that he could not “stress how dangerous” conditions were, in particular in the northeastern town of Brechin.
Emergency services were battling to reach trapped residents but were hampered by strong currents and flooding of up to nearly 2m.
“It’s just absolutely horrendous. I’ve never seen anything like it,” said local councillor Jill Scott, adding that hundreds of homes had been flooded.
“People are trapped…Some have been stuck there for hours.”
“The boats are trying to get to them (but) they can’t get to them because the current is too strong.”
“It’s all white water running round there. It’s like a river,” she added.
Firefighters and the coast guard began evacuating residents in Angus yesterday, knocking on doors and urging people to leave.
“Over 350 homes across Angus were contacted yesterday (Thursday) and advised to evacuate,” a spokesman for Angus council said.
“Brechin, and increasingly other parts of Angus, are now only accessible via boat,” he added.
Train services meanwhile were severely disrupted as far south as the central UK due to heavy rainfall and high winds.
Some routes in northwest UK and north Wales were completely closed due to flooding, rail officials said.
The Meteorological Office has issued a string of less severe yellow and amber warnings indicating adverse weather conditions including flooding, heavy rain, and high winds for other parts of central and northern UK.
