Further detail
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.
