Headline

Heavy rain may cause some flooding and disruption to travel.

What to expect?

  • Some communities may be cut off by flooded roads
  • Spray and flooding could lead to difficult driving conditions and some road closures
  • Homes and businesses could be flooded, causing damage to some buildings
  • Fast flowing or deep floodwater is possible, causing a danger to life
  • Delays or cancellations to train and bus services are possible

Further details

An area of rain is expected to develop across eastern and central England and then move northwestwards to affect northern England and north Wales during Wednesday afternoon. The area of rain could then become slow moving, heavy and persistent, especially over north facing hills, before clearing during Thursday morning. There is a lot of uncertainty over exactly where the heaviest rain will occur and this warning is likely to be updated. Many places will see 30-40 mm of rain, while a few areas may receive 60-80 mm. There is also a small chance that a few upland areas could see much higher totals, in the order of 100-150 mm. What should I do? Check if your property could be at risk of 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. 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.

Some adjustments to the 'further details' section.

Further details

Slow-moving heavy showers are expected to develop, especially across central and western parts of Northern Ireland, through the late morning and into the afternoon. In some areas 20-30 mm could fall in just an hour or two, with the wettest spots perhaps seeing as much as 50-60 mm. Hail and lightning may be secondary hazards in places. Showers and storms should ease into the evening. 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.
