Warning to wave watchers ahead of 'storm surge'

Warning to wave watchers ahead of 'storm surge'

Published by Sarah Yeoman at 7:01am 28th September 2019. (Updated at 5:15pm 28th September 2019)

Storm watchers in Cornwall are being urged to take care as another weather warning goes out for downpours.

The Met Office yellow alert will be in force from 6pm on Saturday evening until 5pm on Sunday evening.

Forecasters say heavy downpours could spark flash flooding for areas north of Bodmin.

It is the third warning for rain in the Duchy in a week.

On top of the that, the Environment Agency has issued 'immediate action' flood warnings for the whole of the south Cornwall coast.

The Kernow Weather Team is also predicting very strong winds along with higher tides, creating a 'storm surge'.

It says conditions could be "extremely dangerous" and people are advised not to go wave watching.

"The wet and windy weather continues for the weekend, with even more heavy rain and strong winds for Saturday and Sunday.

"Not only that, we have a new moon on Saturday and a lunar perigee on Monday (the moon's closest approach to earth) this will also produce higher tides. Alongside this, we have very strong gusts of wind 50+mph on Saturday and Sunday, causing somewhat of a storm surge, putting some coastal areas at risk.

"Saturday remains unsettled, with some very heavy downpours of rain, showers could still be heavy and lengthy, this is something to keep an eye throughout the day.

"By late afternoon, another Atlantic depression moving in from the South West, will bring even more wet and blustery wind that'll be giving gusts of 50 to 55mph along parts the coasts and exposed areas by the early hours. 
"Localised gales are possible, please stay safe and drive to the road conditions. Overall temperatures 14-18c.

"These strong winds and heavy showers which could be prolonged, will continue well into Sunday. While there's still some uncertainty for Sunday, due to the speed this low weather system moves away, its currently looking to be wet, with strong winds from the west or the southwest for a while, 30-55mph once again local gales are possible, more updates on our weather soon.

"Please take extra care if you're out wave watching over the weekend. Very high tides and strong winds could make this extremely DANGEROUS, it only takes one wave and well you know what the outcome could be".

Kernow Weather Team

What can we expect?

  • Flooding of a few homes and businesses is likely
  • Spray and flooding on roads probably making journey times longer
  • Bus and train services probably affected with journey times taking longer
  • Some interruption to power supplies and other services likely

"An area of persistent, heavy rain will arrive from the south-west by Saturday evening before moving east overnight and through Sunday.

"The rain should clear from the south-west on Sunday morning but will persist over parts of north Wales and northern England through much of Sunday.

"Through the period many parts of this area will see 20 to 30mm of rain.

"Where the heaviest rain will fall remains uncertain but there is the potential for 30 to 40mm of rain to fall within a few hours in places as well as 60-70mm over the higher ground of Dartmoor, Wales and the Peak District".
