Weather warning out for torrential rain in Cornwall

The Met Office has issued a severe weather warning for Cornwall, for torrential rain.

The yellow alert will be in force from just after midnight until 8pm on Sunday.

Forecasters say scattered and sometimes thundery showers will spread across, with the risk of heavy downpours and possible thunderstorms.

That could lead to flooding, especially on the roads, and possible power cuts as well.

What can we expect?

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

What is the forecast?

“Scattered thundery showers will move north across parts of England and Wales at times overnight, whilst areas of heavy rain will probably move northwards during Sunday.

“Although some places may stay dry, 30-40 mm could fall in 3-6 hours in a few spots.

“The rain will clear away northeastwards during the afternoon, but will be followed by heavy showers or thunderstorms in southwest England and perhaps Wales, which could give a further 20-30 mm in 1-2 hours”.
