The Met Office said the dangerous weather phenomenon known as a sting jet – a small area of highly intense wind inside a storm – could form later on Friday.
Met Office chief meteorologist Paul Gundersen said: “After the impacts from Storm Dudley for many on Wednesday, Storm Eunice will bring damaging gusts in what could be one of the most impactful storms to affect southern and central parts of the UK for a few years.
“The red warning areas indicate a significant danger to life as extremely strong winds provide the potential for damage to structures and flying debris.”
