Region: South West England

Fog patches will affect parts of central and southeast England on Thursday morning. Some areas will not see fog, but where it does form it may be dense in places with visibility below 100 metres, leading to difficult travel conditions. Fog will slowly clear from the west after dawn but may linger until mid morning in the east of the warning area. What Should I Do? Give yourself the best chance of avoiding delays by checking road conditions if driving, leaving extra journey time, or amending plans if necessary. Make sure you know how to switch on your fog lights, and check they are working before setting off on your journey. Bus and train services, as well as flights may also be affected; check for updates from your travel company and follow their advice. Be prepared for weather warnings to change: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.

Fog patches may lead to some travel disruption.

Region: South West England

A period of rain, heavy at times, especially over high ground, will move slowly east across this region during Wednesday. Coming off the back of recent very wet weather, some travel disruption and flooding is likely across much of the warning area. 10-20 mm of rain is likely to accumulate quite widely across the warning area, but 40-60 mm is possible over the high ground of Dartmoor and the hills of south Wales. Rain should clear to the east during Wednesday evening and into the early hours of Thursday. What Should I Do? Check if your property could be at risk of flooding. If so, consider preparing a flood plan and an emergency flood kit. Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary. 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. Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.
