What do the warning colours mean?
Red warning
- Dangerous weather is expected and, if you have not done so already, you should take action now to keep yourself and others safe from the impact of the severe weather.
- It is very likely that there will be a risk to life, with substantial disruption to travel, energy supplies and possibly widespread damage to property and infrastructure.
Amber warning
- There is an increased likelihood of impacts from severe weather, which could potentially disrupt your plans.
- This means there is the possibility of travel delays, road and rail closures, power cuts and the potential risk to life and property.
Yellow warning
- Yellow warnings can be issued for a range of weather situations.
- It is important to read the content of yellow warnings to determine which weather situation is being covered by the warning.

Torrential rain, with thunderstorms in places, could lead to some significant surface water flooding during Saturday morning
What should I expect?
- Some communities likely to become cut off if roads flood
- Where flooding or lightning strikes occur, delays and some cancellations to train and bus services are likely
- Spray and sudden flooding probably leading to difficult driving conditions and some road closures
- Power cuts likely to occur and other services to some homes and businesses could be lost
- Flooding of homes and businesses is likely and could happen quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds
- Fast flowing or deep floodwater is likely, causing danger to life
What should I do?
Further detail
Areas of heavy rain with embedded thunderstorms will move northwards during the early hours of Saturday, with torrential downpours in places. Accumulations of 20-40 mm are possible in 1 hour, and where heavy downpours persist then as much as 70-100 mm could accumulate in just a few hours. Significant impacts are possible if this occurs over more urban areas.
The more widespread heavy rain should clear to the north during Saturday morning, but additional scattered heavy showers and a few thunderstorms could develop during Saturday afternoon and early evening, this risk covered by the much larger Yellow thunderstorm warning.
What Should I Do?
Keep yourself and others safe; prepare to avoid travelling by road during potentially dangerous road conditions. If you must travel, ensure you watch for possible danger and drive cautiously.
It is not safe to drive, walk or swim through floodwater, avoid it where possible and if you are affected by fast flowing or deep-water call 999, and wait for help.
Preparing a flood kit could save you from loss or damage due to flooding to your home or business. Include: insurance and any other important documents; a torch & spare batteries; first aid kit, prescription medicines and supplies for looking after your family members or pets such as warm, waterproof clothes, blankets, food, and water.
Being outside in high winds and/or lightning makes you more vulnerable to injury. Stay indoors as much as possible. If outside, try not to walk, or shelter, close to buildings or trees, or other structures which could be struck by lightning. If you hear thunder, and are unable to get to a safe enclosed shelter (such as a car), crouch down in a ball-like position with your head tucked in and hands over your ears making minimal contact with the ground, away from objects that conduct electricity.
Before gusty winds arrive, check to ensure moveable objects or temporary structures are well secured. Items include; bins, garden furniture, trampolines, tents, gazebos, sheds, and fences.
Consider checking on vulnerable people that you know including older people, those with underlying conditions and those who live alone; they may need support with food and medical supplies.
If you are worried about your health or that of somebody you know, ring NHS 111.
Stay up to date with the weather forecast for your area and follow advice from emergency services and local authorities.

A few scattered showers or thunderstorms may persist well into the evening
What should I expect?
- Delays to train services
- Some short term loss of power and other services
- Some damage to a few buildings and structures from lightning strikes
- Driving conditions will be affected by spray, standing water and/or hail, leading to longer journey times by car and bus
- Some flooding of a few homes and businesses, leading to some damage to buildings or structures
What should I do?
Further detail
Whilst most scattered showers and thunderstorms will fade this evening, a few may continue to develop, with the potential for up to 20 mm to fall in less than an hour in one or two places.
What Should I Do?
Consider if your location is at risk of flash flooding. If so, consider preparing a flood plan and an emergency flood kit.
Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary.
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.
