Overall

A frontal zone will bring heavy rain throughout today (Thursday) before the winds strengthen later in the day bringing gale force winds through this evening and overnight into Friday, and possibly severe gales in a few places.

Storm Bronagh will bring wind gusts of 45-50 mph quite widely around exposed coasts and in a few spots inland, while some gusts of 60-65 mph are possible, particularly overnight into Friday across eastern England. The strong winds will be accompanied by short-lived outbreaks of squally heavy rain in places.

Met Office Chief Meteorologist Paul Gundersen said: “Although the strongest winds are expected to occur as Storm Bronagh moves offshore into the North Sea, there is a low likelihood of damaging winds in places through this evening and overnight with possible could impacts to people travelling in England and Wales. However the strongest winds are most likely along the north east coast of England in the early hours of the morning."
There is the possibility of damage to buildings, such as tiles blown from roofs or through falling trees and branches, as well as a danger to life. 

Highways England’s Head of Road Safety, Richard Leonard, said: “We’re encouraging drivers to check the latest weather and travel conditions before setting off on journeys. If you do intend to travel, then plan your journey and take extra care, allowing more time for your journey.
“In high winds, there’s a particular risk to lorries, caravans and motorbikes so we’d advise drivers of these vehicles to slow down. Drivers of other vehicles should be aware of sudden gusts of wind which can affect handling and braking, and give high-sided vehicles, caravans, and motorbikes plenty of space.”

***
Looking further ahead there is another weather system expected to bring more wind and rain across parts of the UK on Sunday and into Monday, with some possible coastal impacts. We'll keep an eye on that and update you over the weekend.

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...
