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.

Thunderstorms and heavy rain may lead to some disruption
What should I expect?
- Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services
- Spray and sudden flooding could lead to difficult driving conditions and some road closures
- Some communities might become cut off if roads flood
- Flooding of homes and businesses could happen quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds
- Power cuts might occur and other services to some homes and businesses could be lost
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.
Prepare to protect your property and people from injury. 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.
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.
Further detail
A broad band of thunderstorms and heavy rain will move north across England and Wales, perhaps becoming slow moving in the afternoon and evening. Accumulations of 20-30 mm in three hours can be expected fairly widely and up to 50 mm in a 12 hour period can be expected in places. There is a small chance that some places may see more than 50 mm in three hours and more than 75 mm through 12 hours, especially over east facing high ground. Lightning and hail of 1-2 cm will also be hazards and, in a very few places, strong gusts may also present a hazard, these most likely in the south of England early on Thursday morning.

Further detail
A band of heavy showers and thunderstorms is expected to move northwards during this morning. A drier, brighter interlude may follow, but with a chance of further showers and thunderstorms breaking out during the afternoon. Many places will miss these, but where they do occur they may be intense with 20-30 mm rain falling in less than an hour and perhaps 40-50 mm in 2-3 hours in a few spots, leading to some surface water flooding. Large hail and frequent lightning are also possible. The showers and thunderstorms will drift northwards and ease during the evening.
