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.

Further Details

A band of rain will move east across the area through Monday to bring a spell of heavy and persistent rain. Rain will reach Cornwall during Monday morning but won't reach eastern parts of the warning area until Monday afternoon. 20-30 mm of rain is expected to fall widely with as much as 40-50 mm over some hills. Conditions will likely improve across Cornwall through the afternoon, but will persist across the east of the area until the end of the day. 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. 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.

Reason for update

Warning area shrunk to parts of County Down.

Periods of rain will develop during Monday afternoon, lasting into Tuesday morning. Rain will be heavy and persistent in places, especially across areas exposed to brisk east-southeasterly winds. Widely 15-30 mm of rain is likely across the warning area, with as much as 50-60 mm across the Mournes. 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: the Met Office recommends staying up to date with the weather forecast in your area.
