DS Risk Warning: Weather

By
Hello all,

The forecast has just worsened for Sunday over part of our customer area! There is now an AMBER warning for snow for just south of Bristol in a line down to Southampton and North across the channel into S. Wales and part of Glos. The area extends down through N. Somerset into Somerset and across into Banes. The YELLOW warning area surrounds the AMBER and is for snow and ice. 

A YELLOW ice warning extends across our whole customer area until 10.00 am on Monday 19th to add to the challenge of the return on Monday morning. It appears there might be some travel difficulty hanging over until then.

There is the potential for a spell of snow, moving west over southwest Britain on Saturday night and become locally heavy on Sunday. Strong easterly winds will lead to some drifting of snow. Travel delays on roads are likely, stranding some vehicles and passengers. Some delays and cancellations to rail and air travel are likely. There is a good chance that some rural communities could become cut off with some disruption to power supplies.

Chief Forecaster's assessment

A weather system is expected to run west along the English Channel and bring a spell of snow to southwest Britain on Sunday, clearing from the east during the afternoon. As less cold air follows from the south, snow may turn to rain along the south coast of Devon and Cornwall. There is the potential for 5-10 cm of snow to fall quite widely, and 15-25 cm over higher ground. However, there remains uncertainty in how this system will develop and its impacts.

DS Risk Warning: 28 March: Extinction Rebellion Demonstration ‘Sound the Alarms’ 10 - 4 pm

By
Hello all, Avon and Somerset Police have informed us of an ‘organised civil disobedience’ event that may take place today, Thursday 28th March, whereby members of Extinction Rebellion and possibly sympathisers are proposing to set off multiple [fire] alarms.  There is no known information on which buildings/when but the assumption is that they will target schools, institutions and public buildings. The Bristol Director Education and Skills has shared this scant information with Bristol schools and nothing more. We haven't heard that it has been distributed more widely so we do so just in case to our Agreement/SLA customers. Fire doesn't give notice of where and when it will occur so our best advice, unless you have a delay on the system that allows checking the status of the issue before the alarm sounders go live, is to take any activation seriously and evacuate. If it turns out to be a hoax, false activation, etc, why not log it as an alternative to your t...

DS Risk Warning: Health - Coronavirus/Covid 19

By
Hello all, We have been asked, and in the light of yesterday's Government announcement, please find our updated draft risk assessment to hopefully cover many of the issues you are now faced with to make provision for a restricted number of pupils in the categories described, while the majority are asked to stay at home. We appreciate this is a huge challenge and more explanation will be very helpful but it does represent an important contribution to helping flatten the curve of infection and protect the vulnerable as far as possible.  In the mix you have more issues to take into account and handle sensitively such as staff who live with the vulnerable, have vulnerabilities themselves, on top of those who indeed already have it themselves, who in the vast majority will shake it off over 7 days and will then be available for work and resistant to further infection, of course.

Delegated Services Risk Warning: Weather; Snow and Ice

By
Hello all, I have just watched the local forecast with interest and await the Met Office web site catching up with it! What was said/shown has been updated with elements of more significance. It appears that there is now potential for snow showers to start across our patch from lunchtime but without major impact. As the afternoon goes on the showers look to then merge into longer spells of snow, which then in the evening becomes persistent somewhere along the M4 ish, and to the north of it before lessening off past midnight. NB: Accumulations estimates vary significantly from the light dusting to perhaps up to 8 cm with elevation. Timings are also in flux so we are advised to check again for updates on a regular basis. I will do this and keep you posted. On this basis a prompt get away at the end of the pupil day for all would look to be appropriate. At the moment I stick with 'curtain time' early Friday morning to see whether it's business as close to normal and on a...
