DS Risk Warning: Weather


Here's the latest from the met office all:

Today the Red warning for Wind and Snow is in place for the area I described earlier. It is to 
the West of our customer area and travel to work area, including South Wales. Around the 
Red area the Amber warning is in place for the majority of the customer area. There is also
 a concern regarding a change to freezing rain over night but less certainty about that.

Please note the timing information:

When the Red warning concludes the for the area it covers the Amber is still in place. 

When the Amber warning concludes a yellow warning remains into Saturday. 

There is then a yellow warning in place for ice until 9.00 am Saturday morning. 

Precipitation isn't forecast for Saturday but temperatures remain around freezing so the 
less cold weather isn't appearing yet. 

Snow showers may occur on Sunday morning with temperatures the same. 

Precipitation isn't forecast on Monday or Tuesday when it does become less cold.

RED warning details today:

Between 15:00 Thu 1st and 02:00 Fri 2nd
A spell of heavy snow and blizzard conditions is expected. The snow will be 
accompanied by very strong easterly winds leading to severe drifting. Some 
places could also see significant ice build up due to freezing rain from later on 
Thursday evening, most likely in the south of the area. Long delays and 
cancellations of public transport seem highly likely. Some roads are likely to 
become blocked by deep snow, stranding vehicles and passengers. Long 
interruptions to power supplies and other utilities are very likely to occur, 
along with damage to trees and other structures due to heavy snow or ice.

Chief Forecaster's assessment

Widespread snow is expected to develop through Thursday afternoon and 
evening. Around 10-20 cm is likely to fall widely, with the potential for up to 
30 to 50 cm over parts of Dartmoor, Exmoor and parts of southeast Wales. 
Snowfall will be accompanied by strong to gale easterly winds, leading to 
severe drifting of lying snow especially in upland areas. Severe cold and 
wind chill will compound the dangerous conditions, with very poor visibility. 
Towards midnight, there is a chance of snow turning to freezing rain in places, 
mainly across the south of the area, with widespread icy stretches making 
driving conditions particularly dangerous.

Amber warning details for today:

Between 14:00 Thu 1st and 08:00 Fri 2nd
A spell of heavy snow is expected. The snow will be accompanied by very 
strong easterly winds leading to blizzards and considerable drifting. From 
Thursday evening some places could also see ice build up due to freezing 
rain. Long delays and cancellations of public transport seem very likely. 
Some roads may become blocked by deep snow, stranding vehicles and 
passengers. Long interruptions to power supplies and other utilities are 
likely to occur, along with possible damage to trees and other structures 
due to heavy snow or ice. This is an update to shrink the amber area 
slightly, removing parts of  southwest Wales as well as central southern 
England. Snow amounts over upland areas have also been increased.

Chief Forecaster's assessment

Widespread snow is expected to develop through Thursday afternoon and 
evening. Around 10-20 cm is likely to fall quite widely, 30-50 cm possible 
across parts of Dartmoor, Exmoor and upland parts of southeast Wales. 
Snowfall will be accompanied by strong to gale easterly winds, perhaps 
severe gales in places, leading to drifting of lying snow especially in upland 
areas. Severe cold and wind chill will compound the dangerous conditions. 
Towards midnight, there is a chance of snow turning to freezing rain in places, 
more likely over southwest England, with widespread icy stretches making 
driving conditions particularly dangerous.

Yellow Warning tomorrow:


Between 00:05 Fri 2nd and 23:55 Fri 2nd

Further snow showers or perhaps longer spells of snow are likely at times 
through Friday. There is an increasing chance that a further spell of more 
persistent snow may move north into parts of southern England, Wales 
and central England during the day. Icy stretches are likely on untreated 
surfaces. In addition, strong winds will lead to further drifting or blowing 
around of existing snow cover. Delays and cancellations to public transport 
are possible, as are delays to travel on roads; some stranding of vehicles 
and passengers could also occur. Some rural communities could become, 
or remain cut off. Interruptions to power  supplies and mobile phone 
coverage are also possible.

Chief Forecaster's assessment

Whilst snow showers over Northern Ireland are likely to ease, further more 
persistent snow could move north into southern Britain later, giving a few cm 
in places. However, there remains significant uncertainty regarding this aspect. 
This warning has been updated to remove the west of Cornwall and the Isles of 
Scilly. A reference to blowing around of existing snow cover has been added.



All the best with your decisions and recovery plans.

DS Risk Warning: UK raises terror threat level to ‘severe’ following Vienna attack

  Home Secretary Priti Patel has confirmed the escalation of the UK terror threat level from "substantial" to "severe" following an attack in Vienna that left at least three dead. The change means that an attack on UK soil is now deemed "highly likely". The Joint Terrorism Analysis Centre has changed the UK terror threat level from substantial to severe. This is a precautionary measure and is not based on any specific threat. The potential is for UK based 'lone wolfs' to be emboldened to take action themselves which could take place anywhere in the UK. We are asked to continue to remain vigilant and report any suspicious activity to the police on 999 or the anti-terrorist hotline: 0800 789 321. If your information does not relate to an imminent threat, you can also contact MI5 . What the threat levels mean: Threat levels are designed to give a broad indication of the likelihood of a terrorist attack. LOW means an attack is highly unlikely MODERATE ...

Delegated Services Risk Warning: Weather; Wind - Storm Darragh

  The Met Office have upgraded the warning for tomorrow as follows: Red weather warning issued  Strong and damaging winds across parts of Wales and southwest England  Saturday 0300 – 1100 Our advice changes in such circumstances to, do all you can today, but any checking approach during the day tomorrow should only be considered in extremis in the red zone and very carefully indeed risk assessed. Beware too the boundaries are changing of the zones, as more data comes in. Checks may need to wait until Sunday. NB: Many are postponing anything planned for tomorrow to allow safety at home in the red zone and extreme caution in the amber. This needs to apply to your sites. We aren't aware from our systems, at present, of any education visit/DofE activities, but obviously these need to be reconsidered. Met Office Chief Forecaster, Jason Kelly, said:  “The worst impacts from Storm Darragh will be felt as we go through the early hours of tomorrow morning and throughout Satur...

Delegated Services Risk Warning: Weather; Snow and Ice

Hello all, I'd set the alarm early, then a picture fell off the wall, even earlier and ..... The forecast suggests there will be some more snow of varying intensity this morning, before it dies out around lunchtime and will become far brighter. It appears the motorways and major trunk roads, (Highways England) and majority of the local council gritted routes are open, albeit that in some locations there are lane restrictions. Elevation impacts on depth of snow and impact on the roads. The position on non cleared routes will vary markedly. Gritting and ploughing is ongoing and extra resources have been deployed. Public transport is running save for Bristol Airport at the moment. It is under review as the position for drivers getting in to the depots is a challenge. First Bus across the patch will issue an update at 6.30 am. However, Metro Bus is running in Bristol and routes along the main gritted routes are running. At present, therefore, I can't be of more...
