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.

What should I do?

Further detail

Heavy showers, perhaps merging into longer spells of heavy rain at times, are likely to reach southwest England and south Wales Thursday night, before pushing quickly east to affect other parts of southern and southeastern England into Friday morning.

Whilst not everywhere will see the heavy showers or rain, where they do occur 10-20 mm of rain in less than an hour is possible. 50-70 mm of rain is possible in a few hours where heavy showers become more prolonged, this most likely near coasts. Some flooding in these wetter areas is possible. A few showers could be accompanied by the odd rumble of thunder, again this more likely near to coasts.

Heavy showers and rain should clear into the North Sea by early afternoon.

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.
