A yellow weather warning has been issued for Southampton ahead of thunderstorms that are expected to hit the region tonight.

The Met Office says lightning strikes are likely to be accompanied by heavy rain, resulting in flooding and travel disruption.

The warning comes into force at 8pm today and is not due to be lifted until 8am tomorrow.

The  Met Office website includes advice on what to expect during thunderstorms.

It says: "Spray and sudden flooding could lead to difficult driving conditions and some road closures.

"Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services.

"There is a slight chance that power cuts could occur and other services to some houses and businesses could be lost.

"There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds."

The  website also includes advice on how to stay safe before, during, and after thunderstorms.

It says: "Lightning can cause power surges, unplug any non-essential appliances if not already using a surge protector.

"Seek shelter if possible. When you hear thunder you are already within range of where the next ground flash may occur. Lightning can strike as far as ten miles away from the centre of a storm.

"Telephone lines can conduct electricity so try to avoid using the landline, unless in an emergency

"If outside avoid water and find a low-lying open place that is a safe distance from trees, poles, or metal objects.

"Avoid activities such as golf, rod fishing, or boating on a lake.

"Be aware of metal objects that can conduct or attract lightning, including golf clubs, golf buggies, fishing rods, umbrellas, motorbikes, bicycles, wheelchairs, mobility scooters, pushchairs, wire fencing, and rails.

"If you are in a tent, try to stay away from the metal poles

"If you find yourself in an exposed location it may be advisable to squat close to the ground, with hands on knees and with head tucked between them. Try to touch as little of the ground with your body as possible. Do not lie down on the ground.

"Avoid downed power lines or broken cables

"If someone is struck by lightning, they often suffer severe burns. The strike also affects the heart, so check if they have a pulse.

"If you are caught out in thunder and lightning it is advised that you wind up the windows and stay inside your car.

"This is because, in the vast majority of cars with a metal roof and frame, the frame will act as a conductive Faraday cage, passing the current around the passengers inside and onto the ground.

"Thunderstorms can also bring a risk of sudden gusty winds, those most at risk would include cyclists, motorcyclists, and high-sided vehicles.

"Hail storms can be extremely dangerous to drive in, reducing your ability to see and be seen, as well as causing damage to your vehicle. If hail is severe, stop and pull over to a safe place and remain inside the vehicle."
