The Neighourhood Watch as it was is being superseded by Community Alerts sponsored by Gloucestershire police.
You will need to sign-up again to continue to receive Alerts. So if you want local information / alerts from the Police / Council / Fire / Environment Agency https://www.yourcommunityalerts.co.uk/ is where you need to sign up.
Not all residents have the internet so maybe if you have an elderly neighbour that can’t access this service you could let them know of any relevant information.
