DOUBLE weather warning for rain and gales in Cornwall

Published by Emma Carton at 7:06am 18th December 2019. (Updated at 12:09pm 18th December 2019)

Another band of gales and torrential rain is sweeping towards Cornwall.

The Met Office has issued a string of weather warnings lasting from Wednesday afternoon through until Sunday night.

We are being told that 70mph winds and downpours could spark flash flooding.

What can we expect?

The Met Office has issued two weather warnings for the Duchy on Wednesday.

The first, for strong winds, will be in force from 2pm until 3am on Thursday.

The gusts could reach 70mph on the coasts, with the risk of:

  • Some coastal routes, sea fronts and coastal communities are likely to be affected by spray and/or large waves, especially for south and southeast facing coastlines.
  • Some delays to road, rail, air and ferry transport are likely
  • Delays for high-sided vehicles on exposed routes and bridges likely
  • Some short term loss of power and other services is possible

The second, for heavy rain, originally covered an area from Plymouth to St Austell but has now been extended to cover the whole of Cornwall.

It will be in force from 2pm on Wednesday through until 12pm on Friday with the risk of:

  • Spray and flooding on roads probably making journey times by car and bus longer
  • Flooding of a few homes and businesses is likely

A third weather warning for downpours has now been issued too, lasting the whole of the weekend from midnight Saturday through until 11.59pm on Sunday, with the risk of further flooding:

  • Where flooding occurs, there is a slight chance of delays or cancellations to train and bus services
  • Spray and flooding could lead to difficult driving conditions and some road closures
  • There is a small chance that homes and businesses could be flooded, causing damage to some buildings

What is the forecast?

"Strong south-easterly winds are expected to develop during Wednesday afternoon across parts of south-west England and west Wales before spreading to Northern Ireland and parts of south-west Scotland later. 

"Winds will tend to ease from the south during Wednesday evening. 

"Most areas will also see a spell of heavy rain. 

"The strongest winds will be for exposed coastal areas and over high ground with a few places seeing gusts reaching 60-70mph. 

"Most inland sites are likely to see wind gusts peak between 45 and 55mph.

"Heavy rain is likely to move eastwards across southwestern areas later on Wednesday. 

"Some 20-30mm of rain could fall in a 6-9 hour period, with perhaps as much as 60mm over Dartmoor and the high ground of south Wales. 

"Falling on saturated ground, this will probably cause a few problems. 

"The rain should become confined to the east of the region by late evening".
