Heavy rain will move northwards across Northern Ireland during Thursday and may lead to some disruption in places.
What should I expect?
- There is a good chance driving conditions will be affected by spray and standing water leading to longer journey times by car and bus
- Delays to train services are possible
- Some flooding of a few homes and businesses possible
- Some short term loss of power and other services is likely
What should I do?
Further detail
An area of rain will move northwards across Northern Ireland during Thursday, before clearing during the late afternoon and evening.
The rain will be locally heavy with thunderstorms. A few places perhaps receiving 10 mm of rain or more in an hour, and 30-40 mm in 3-6 hours, leading to a risk of disruption.
Winds will also be strong at times, perhaps gusting to 40-45 mph around hills and coasts..
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.
Being outside in high winds and/or lightning makes you more vulnerable to injury. 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.
Stay up to date with the weather forecast for your area and follow advice from emergency services and local authorities.

Reason: There is a reduced likelihood of impacts from thunderstorms within the warning area given recent evidence however there remains a risk of thunderstorms developing. The area has been extended slightly eastwards and the end time also extended as there is potential for some further thunderstorm activity to develop this afternoon as the main rain area clears northwards.

Sat 14
Thunderstorms may bring some disruption during Friday evening, and overnight into Saturday.
What should I expect?
- Spray and sudden flooding could lead to difficult driving conditions and some road closures
- There is a small chance that some communities become cut off by flooded roads
- 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 homes 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
- There is a small chance of fast flowing or deep floodwater causing danger to life
What should I do?
Further detail
Thunderstorms are possible across parts of eastern and southeastern England from Friday afternoon through to the early hours of Saturday. Although many places within the warning area may not see any impacts, torrential downpours could bring 30-50mm of rain, with a risk of even greater accumulations should thunderstorms line up, and with much of the rain perhaps falling in a short space of time, leading to a risk of surface water flooding. Thunderstorms may also bring large hail, gusty winds and frequent lightning to some places which could cause damage and power cuts.
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.
