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.

Rain is expected to arrive into the region during Wednesday evening, becoming persistent overnight and turning heavier during Thursday. Rain is expected to clear away during Thursday afternoon. 30-40 mm is likely to fall quite widely, with peaks of 60-80 mm over some mountains of south Wales. 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.

Persistent and at times heavy rain, along with some snow melt, likely to lead to some disruption to travel in places.

What to Expect

  • Flooding of a few homes and businesses is possible
  • Spray and flooding on roads and perhaps railways probably making journey times longer

What should I do?

Further Details

Rain setting in on Wednesday evening, will turn heavier for a time overnight, and then again during Thursday afternoon, before clearing during the evening. 20-40 mm of rain is likely quite widely, with 50 to 80 mm possible on some of the southern fells. Snow melt from the fells is likely to boost river flow in places, and a few places might see drainage affected by recent snow ploughing, all increasing the possibility of a few flood impacts. 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 possible, allow extra time. Be prepared for weather warnings to change; the Met Office recommends staying up to date with the weather forecast in your area. Check if your property could be at risk of flooding. If so, consider preparing a flood plan and an emergency flood kit.

Rain will be accompanied by strong southeasterly winds. Further heavy rain is possible in similar areas on Friday but this aspect is currently unclear. What should I do?
