What can residents expect?

With the yellow rain warning in place for much of the weekend, the Met Office has said that that Storm Dennis will bring ‘very heavy rain’.

There is a chance of flooding and disruption to travel over the weekend.

On its website, the Met Office says: ‘Spells of heavy and prolonged rain are expected to affect parts of England and Wales over the weekend with a higher likelihood of impacts now expected in some areas.

‘Around 20-40 mm of rain will fall widely with 50-80 mm likely across parts of northern and southern England.

‘Over the higher ground of Wales and southwest England, 120-140 mm of rain is possible in a few locations. This rain is expected to fall across areas already wet from recent rainfall.’

For the areas covered by the amber warning on Sunday, residents are warned that they could expect:

- Homes and businesses are likely to be flooded, causing damage to some buildings

- Fast flowing or deep floodwater is likely, causing danger to life

- Delays and some cancellations to train and bus services are likely

- Power cuts and loss of other services to some homes and businesses likely

While Storm Dennis is also expected to bring gusts of up to 70mph in places throughout the weekend.

The gales are expected to be strongest on Saturday afternoon heading into the evening and then picking up again in the early hours of Sunday.

Currently the Met Office is predicting that the winds will reach speeds of 59mph between 6am and 9am on February 16.
