Forecasters say the impacted regions can expect to see frequent lightning strikes and heavy downpours.
A Met Office forecast said: "Areas of heavy rain and some thunderstorms are likely to move northwards into southwest England and Wales on Friday evening.
"Rainfall amounts and thunderstorm activity will vary across the area however there is the potential for 20 mm of rain to fall in an hour and 30-40 mm to fall in 3 hours or less in a few places.
‌
"As well as this there is a small chance of frequent lightning and hail within the rain area as additional hazards."
Members of the public have been warned that "some flooding of a few homes and businesses is likely, leading to some damage to buildings or structures".
They are warned to expect "some damage to a few buildings and structures from lightning strikes; There is a good chance driving conditions will be affected by spray, standing water and/or hail, leading to longer journey times by car and bus; Delays to train services are possible; Some short term loss of power and other services is likely".
‌
During intense thunderstorms, the advice is as follows:
"Consider if your location is at risk of flash flooding. If so, consider preparing a flood plan and an emergency flood kit.
"People cope better with power cuts when they have prepared for them in advance. It's easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items. If you find yourself outside and hear thunder, protect yourself by finding a safe enclosed shelter (such as a car).
‌
"Do not shelter under or near trees, or other structures which may be struck by lightning. If you are on an elevated area move to lower ground. Be prepared for weather warnings to change quickly."
When a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.
