Weather Alerts
Spells of heavy rain could lead to some flooding and disruption to travel during Wednesday and Thursday.
Spells of rain, some heavy, will affect southern parts of England during Wednesday and overnight into Thursday, whilst some snow is also likely over higher ground, chiefly during Wednesday night. 10-20 mm of rain is expected quite widely with a few places near the south coast seeing 20-30 mm and perhaps as much as 50 mm over Dartmoor. Strong east to northeasterly winds will accompany the rain and/or snow, which could exacerbate impacts in places. Large waves could affect some east-facing coasts, especially along the English Channel. For further details see https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings
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.
