Huddersfield was drenched by two-third of a month’s rain in just 24 hours.
And Huddersfield weather expert Paul Stevens warned: “There is more on the way”.
The town itself had 44mm or 1.7in of rain between Saturday lunchtime and Sunday lunchtime, with most falling on Saturday night.

Other parts of the region were hit even harder, with Meltham getting 60mm and parts of the Calder Valley suffering from 95mm of rain.
The average for the whole of November is about 65mm.
The heavy rain eased slightly this morning but two more bands of rain are expected to sweep through overnight .
Mr Stevens said: ”It is as bad as we predicted.
“The heavy rain started on Saturday afternoon and continued through much of the night, causing a lot of problems for the drains and the roads.
“Tonight we will see two more bands of heavy rain sweep through, with one bringing another 10 - 15mm of rain and the second about 20mm.
“Monday night there will be more rain, and that will again be repeated on Tuesday, with up to another 30mm of rain falling.
“It means by the time we get to Wednesday we could have seen well over 100mm of rain in just four days.
“That is considerably heavier than normal and it is falling on already saturated ground which is likely to mean more flooding problems on the roads”.
And there are more problems to come, said the forecaster.

“If the rain is not enough then we are in line for the first cold snap of the winter.
“By the end of the week and into the weekend, the winds are coming straight from the Arctic and bringing us temperatures down to 3°C, which is noticeably colder.
“There is also a lot of rain about so that could well fall as snow on land above 500 feet and I would not be surprised if we saw the first snow of the season in the town itself”.
