Following some rain on Wednesday, then a bit of a lull for most areas early Thursday morning, heavier rain is expected to return across southern counties of England from mid-morning onwards. This has potential to cause some disruption to travel, along the with the possibility of some flooding. Widely 15-25 mm is likely across the warning area, but 40-50 mm may fall in some places, most likely over the Downs. In addition, the rain will be accompanied by strong winds, with a chance of gusts approaching 60 mph on exposed southern coasts, and 40-50mph possible inland. Rain will clear to the east by the end of the day.. 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.

Heavy rain on Thursday may cause disruption to travel with some flooding possible in a few places.

An area of heavy rain will move northeast across the warning area during Thursday morning and afternoon before clearing to the east through the evening. Given recent very wet weather, there is potential for some disruption to travel and possible flooding. Much of the warning area will see 15-25 mm but some places could see 40-50 mm, with the highest totals falling over high ground of south Wales and Dartmoor. In addition, strong winds will accompany the rain, and may exacerbate some of the impacts. There is a chance of 60-70mph gusts along the exposed south coast, and perhaps 40-50mph some way inland across southwest England. What Should I Do?
