  • Fast flowing or deep floodwater is likely, causing danger to life

Further Details

Rain becoming heavy and persistent during Wednesday afternoon before easing during Thursday morning. The heaviest rain is expected over north facing hills and where strong winds will enhance rainfall accumulations. Many places within the warning area will see 30-40mm of rain, with high ground of northwest England seeing 70-90 mm. While mountains of north Wales may see 100-150mm or more. 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. Stay up to date with the weather forecast for your area and follow advice from emergency services and local authorities

Reason for update

Warning area adjusted further south in parts of the east whilst trimming the southern extent in the west. End time extended to cater for heavier rain persisting for longer over North Wales and northwest England. Further updates are likely to trim the warning area as rain clears northwestwards through the period.

An area of heavy rain will affect much of England and Wales during today, slowly clearing from eastern parts of England through the day. The area of rain is likely to become heavy and persistent over parts of northern England and North Wales, particularly north facing hills, before easing during Thursday morning. Many places will see 30-40 mm of rain, while a few areas may receive 60-80 mm. There is also a chance that a few upland locations, chiefly in the separate Amber warning area, 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.

Further Details

An area of heavy rain is expected to move northwestwards across the warning area during late Wednesday afternoon and persist overnight into Thursday morning, before turning somewhat lighter and patchier. Through this period, 20-30 mm of rain may accumulate quite widely, but some north-facing high ground may see well in excess of 60 mm of rain. Strong and gusty northerly winds may exacerbate any impacts from the rain. 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.

Scattered showers and thunderstorms may lead to some disruption.

What to Expect

  • 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 homes and businesses could be lost

What should I do?

Further Details

While many places will remain dry, scattered showers are expected through Wednesday. Where these develop they are likely to be heavy at times, with a risk of hail and thunder. A few places may see 10-20mm in 1hr and perhaps 30-40mm in 2-3 hours. What should I do? 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. 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.

Reason for update

Warning area expanded westwards to include the western Central Belt, Kintyre and Arran.

An area of heavy rain is expected to move northwest across Scotland from Wednesday afternoon, with rain most persistent across northern and eastern facing high ground. For many areas, rain should gradually become more showery in nature during Thursday, but at the same time, some heavy, slow-moving downpours may develop across parts of southern and eastern Scotland. 20-40 mm may accumulate quite widely through this period, but in excess of 60 mm is quite possible over some northern and eastern facing high ground. Locally strong and gusty winds through Wednesday evening and early on Thursday may exacerbate any impacts from the rain. 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.

Heavy rain may bring some disruption to northeastern parts of Northern Ireland.

What to Expect

  • There is a slight chance of power cuts and loss of other services to some homes and businesses
  • There is a small chance that homes and businesses could be flooded, causing damage to some buildings

Further Details

An area of heavy rain is expected to move westwards into eastern parts of Northern Ireland during Wednesday. Whilst many areas may only see modest amounts of rain, there is the potential for parts of Antrim in particular to see 30-50 mm of rain quite widely and perhaps in excess of 60-80 mm over windward facing higher ground. Rainfall should tend to ease later on Thursday morning. Strong north to northwest winds, perhaps gusting to 50 mph at times, will likely exacerbate any impacts from the rainfall. 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.
