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.

Heavy rain may bring some flooding and travel disruption in places on Monday night into Tuesday

What should I expect?

  • There is a slight chance of power cuts and loss of other services to some homes and businesses
  • Homes and businesses could be flooded, causing damage to some buildings
  • Fast flowing or deep floodwater is possible, causing a danger to life
  • Delays or cancellations to train and bus services are possible
  • Spray and flooding could lead to difficult driving conditions and some road closures
  • Some communities may be cut off by flooded roads
  • Possible power cuts and loss of other services to some homes and businesses

What should I do?

Further detail

Outbreaks of rain will become persistent and heavy on Monday night into Tuesday morning, and whilst the rain may be more intermittent during Tuesday daytime some occasional heavy bursts will still be possible. There will naturally be some variation in rainfall totals across the area, but accumulations of 20-40 mm are likely in quite a few places, with 60-80 mm over Dartmoor and high ground in Wales. There is a small chance of 80-100 mm falling over the most exposed, prone hills. Given the saturated nature of the ground, this is likely to lead to some flooding in places and transport disruption. Rain will also be accompanied by strengthening southerly winds, which may exacerbate impacts.

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.

Strong winds may cause some disruption on Monday night into Tuesday

What should I expect?

  • Some delays to road, rail, air and ferry transport are likely
  • Probably some bus and train services affected, with some journeys taking longer
  • Delays for high-sided vehicles on exposed routes and bridges likely
  • Some short term loss of power and other services is possible
  • It’s likely that some coastal routes, sea fronts and coastal communities will be affected by spray and/or large waves

What should I do?

Further detail

South to southwesterly winds will strengthen on Monday night and remain strong and gusty into Tuesday morning, before gradually easing through Tuesday afternoon. Peak gusts of 40-50 mph are expected fairly widely, but gusts of 60-70 mph will be possible along some exposed coasts and over/to the north of high ground. There is a small chance of gusts in excess of 70 mph over northwest Wales.

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.

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.

Peak gusts around 60 mph are possible fairly widely, and potentially in excess of 70 mph for some exposed headlands and high ground. There is a small chance of even stronger winds should the area of low pressure pass closer to western Scotland. Winds should gradually ease through Wednesday morning.

Further detail

Outbreaks of rain will become persistent and heavy on Tuesday morning, before clearing into the afternoon. Accumulations of 20-40 mm are likely over some hills, with up to 80 mm possible over high ground in Cumbria. Given the saturated nature of the ground, this is likely to lead to some flooding in places and transport disruption. Rain will also be accompanied by strengthening south to southwesterly winds, with gusts in excess of 60 mph possible over high ground, which may exacerbate impacts, especially on routes across the Pennines.
