Storm Austen likely to bring some disruption and possible damaging winds on Friday morning.
Effective: Fri October 23, 2026, 3:00 AM
Expires: Fri October 23, 2026, 10:00 AM
A spell of very strong northwesterly winds is likely on Friday morning. There is a good chance that gusts of 60-70 mph will develop widely for a time with perhaps some gusts around 80 mph for exposed headlands. Very strong winds will be combined with spells of heavy rain. Remaining windy for the rest of Friday but winds will gradually ease. For further details see https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings
Driving in these conditions can be dangerous, for yourself and other road users. If you must drive, you can do this more safely by taking the following actions; drive slowly to minimise the impact of wind gusts, be aware of high-sided vehicles/caravans on more exposed roads and be cautious when overtaking, and give cyclists, motorcyclists, lorries, and buses more room than usual. Being outside in high winds makes you more vulnerable to injury. Stay indoors as much as possible. If you do go out, try not to walk, or shelter, close to buildings and trees. In advance of high winds, check for loose items outside your home and secure them. Items include: bins, garden furniture, trampolines, tents, sheds, and fences. If you are on the coast, stay safe during stormy weather by being aware of large waves. Even from the shore large breaking waves can sweep you off your feet and out to sea. Take care if walking near cliffs; know your route and keep dogs on a lead. In an emergency, call 999 and ask for the Coastguard. People cope better with power cuts when they have prepared for them in advance. It's easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items. Stay up to date with the weather forecast for your area and follow advice from emergency services and local authorities.
