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.

Areas of heavy, possibly thundery rain may cause flooding and disruption in parts of England and Wales on Saturday night and Sunday

What should I expect?

  • There is a slight chance of power cuts and loss of other services to some homes and businesses

  • Where flooding occurs, there is a slight chance of delays or cancellations to train and bus services
  • Spray and flooding could lead to difficult driving conditions and some road closures
  • There is a small chance that some communities will become cut off by flooded roads
  • There is a small chance of fast flowing or deep floodwater causing danger to life

What should I do?

Further detail

Whilst there remains some uncertainty with exact details, areas of heavy and at times thundery rain are expected to spread north, then west, across England and Wales from this evening and overnight. These areas of heavy rain may become more persistent across western areas during Sunday daytime whilst slow-moving heavy showers and thunderstorms are likely to develop further east. Rainfall amounts will vary considerably across the warning area with some locations seeing less than 10 mm of rainfall whilst others see 40-60 mm of rain. There is a lower chance that a few spots within the warning area could see 80-100 mm of rain by the end of Sunday which may fall in a fairly small period of time. These higher totals are slightly more probable in the southern half of the warning area. Given this region has also seen a lot of rain since Thursday, impacts may be more likely than would normally be expected for the time of year here. 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.
