Transport links also suffered after Frank rolled in from the Atlantic, with high winds shutting the Clifton Suspension Bridge for only the second time in its 151-year-old history before it was reopened around lunchtime.
Roads have been flooded including a stretch of the M4 motorway near Cardiff, while the torrent of rain also caused a landslip at Rest & Be Thankful in Argyll Scotland closing the A83.

Lisa Pinney, an Environment Agency spokesman, said river levels had been falling but the renewed rainfall increased the risk of renewed flooding in already saturated areas like Cumbria, Lancashire and Yorkshire.
She added that persistent rainfall in Wales meant there was also now a chance of flooding in the west and south west of England.
Ms Pinney, a flood manager, said: "We're expecting more rain today and into the late afternoon, so we're encouraging people to be aware.
"Based on the forecast we've had, we're not expecting to see scenes like we've had over the past few days and not see flood defence over-topping, for example.
"But we're aware the ground across the north of England is absolutely saturated. We're not complacent."
Earlier, EA chairman Sir Philip, returning from his holiday, spoke briefly to reporters outside his flat in Marylebone in London saying he would be visiting Yorkshire later, and would be "very happy to speak" with people when he got there.
The timing of his Caribbean break had been criticised, although the EA pointed out he had visited flood victims in Cumbria earlier this month.
An agency spokesman said Sir Philip had been in "regular contact" with the organisation regarding its response to the current situation.
The agency later confirmed he had visited Yorkshire.

Earlier today, a 40-year-old was arrested on suspicion of theft in Mytholmroyd, following reports of suspicious activity around flooded homes West Yorkshire Police said.

In many areas the ground is still saturated from previous downpours and river levels remain at record highs.
Although the floodwaters have been receding, across the North, more than 6,700 homes have flooded in the past week.
