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.

Reason for update

The start time has been brought forward, whilst the end time has been put back to Friday morning. Rainfall totals have also been adjusted.

Further rain, heavy at times, is expected through Thursday. Rain will ease for a time Thursday evening, before further spells of rain or showers arrive from the south Thursday night, these clearing Friday morning. Accumulations of 15-25 mm expected widely. Some places are likely to see 25-30 mm, locally in excess of 40 mm, especially across the Antrim hills. 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

A deep area of low pressure will bring a spell of very windy weather to parts of southwest and then southern England on Thursday. Gusts of 50 mph are expected quite widely, while some exposed coastal spots may experience gusts of 60 to 70 mph, with large waves also likely. The strong winds will be accompanied by heavy, squally showers with the possibility of hail and thunder in some locations. Hail won't fall everywhere but where it does it can quickly make road surfaces slippery, while surface water and spray are likely to worsen travel conditions rather more widely. What should I do? Prepare to protect your property and people from injury. Check for loose items outside your home and plan how you could secure them. Items include; bins, garden furniture, trampolines, tents, sheds and fences. 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. If you are on the coast, stay safe during stormy weather by being aware of large waves. Even from the shore large breaking waves can sweep you off your feet and out to sea. Take care if walking near cliffs; know your route and keep dogs on a lead. In an emergency, call 999 and ask for the Coastguard. 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.
