Headline

Heavy rainfall combined with some snowmelt across the hills is likely to lead to flooding.

What to expect

  • Homes and businesses are likely to be flooded, causing damage to some buildings
  • Fast flowing or deep floodwater is likely, causing danger to life
  • Delays and some cancellations to train and bus services are likely
  • Spray and flooding probably leading to difficult driving conditions and some road closures
  • A good chance some communities cut off by flooded roads
  • Power cuts and loss of other services to some homes and businesses likely

Reason for update

The area of the warning has been extended southeastwards and parts of the northern edge trimmed. Areas removed from this warning will be covered by a different NSWWS warning.

Further details

Rain developing during Monday persists into Wednesday and Thursday, this rain associated with Storm Christoph. Rain will be heaviest and most persistent across western facing hills. Over 100 mm of rain is expected across the higher ground with the potential for 150-200 mm of rain in the most exposed areas. The rain will also lead to rapid melting of any remaining lying snow across the higher peaks adding to water entering the river network. Strong winds will accompany the rain at times and may add to travelling difficulties across higher and more exposed routes.

Headline

Spells of prolonged and heavy rain may lead to flooding and disruption to travel in places.

What to expect

  • 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

Reason for update

The warning has been extended southwards to encompass more of the Midlands.

Further details

Several days of persistent, and occasionally heavy, rain are expected to affect the region as Storm Christoph affects the UK. The heaviest and most persistent rain is likely to be across Wales and the high ground of northern England. By early Thursday, 30-60 mm of rain is expected to have fallen widely across the warning area, with 100-150 mm over the high ground of Wales and northern England. Up to 200 mm is possible across parts of north Wales and northwest England. Melting snow across higher parts of the Pennines may exacerbate the potential for flooding. Strong winds will also accompany the rainfall and may add to travelling difficulties across areas higher and more exposed routes.

Headline

Spells of heavy rain may lead to travel disruption and flooding in places.

What to expect

  • Flooding of a few homes and businesses is likely
  • Bus and train services probably affected with journey times taking longer

Further details

Occasional heavy rain is expected to affect the region from Wednesday onwards into early Thursday as Storm Christoph affects the UK. The heaviest and most persistent rain is likely to be across the higher ground in the southwest. 20-30 mm of rain is expected to fall widely across the warning area with areas of 40-50 mm most likely in southwest England and along the south coast towards Hampshire. 75-100 mm is also likely over the moors in the southwest. Some stronger winds may also accompany the rainfall and may add to travelling difficulties across higher and more exposed routes.

  • Some rural communities could become cut off
  • Power cuts may occur and other services, such as mobile phone coverage, may be affected

Further details

Persistent rain over southern Scotland and the far north of England will increasingly fall as snow above around 100 m during Wednesday afternoon and overnight into Thursday. A few cm of wet snow may accumulate down to around 100 m but above 200 m 10-15 cm may settle with perhaps 20-30 cm above 400 m. Rain is more likely on lowest ground near the east coast and may bring some localised surface water flooding

  • Aberdeen

Headline

Heavy snow and strong winds will bring blizzard conditions in places leading to travel disruption on Thursday.

What to expect

  • Possible travel delays on roads stranding some vehicles and passengers
  • Possible delays or cancellations to rail and air travel
  • Some rural communities could become cut off
  • Power cuts may occur and other services, such as mobile phone coverage, may be affected

Reason for update

The warning area has been expanded and the start time of the warning has been delayed. There is also an increase in likelihood on the impact matrix.

Further details

An area of rain associated with Storm Christoph will push in from the northeast, turning readily to snow away from coasts and at even modest elevation. Snow accumulations of 5-10 cm are possible in places at low levels whilst 10-15 cm is likely above around 200 m with perhaps 30-40 cm above 400 m. Along north facing coasts and particularly north Aberdeenshire the precipitation will stay as rain with widely 20-30 mm of rain falling during the period and a few sites perhaps seeing around 50 mm. In addition strong winds will develop through Thursday with gusts of 60 mph along the north facing coasts perhaps an additional hazard. These stronger winds will also lead to very poor conditions where snow falls with blizzard conditions at times over higher ground. Inland from the coast with wet snow likely this may lead to icing on infrastructure, such as power lines.

  • There is a slight chance of power cuts and loss of other services to some homes and businesses

Further details

Persistent, and at times heavy rain, will develop across Northern Ireland, southern Scotland and the far north of England during Monday night. Rainfall accumulations of 20-30 mm are expected quite widely and some places, mostly over higher ground, could see 30-50 mm rain. This wet weather will clear eastwards early on Wednesday. Later on Tuesday rain will also turn to snow over hills, initially down to 300-400 m and then down to 100-200 m Tuesday evening and night. The most widespread snow will be over southern Scotland where accumulations of 2-5 cm are possible above 200-300 m and 5-10 cm may fall above 300-400 m.

  • 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.
