Weather Alerts
Heavy rain during Monday afternoon and evening may cause some flooding and disruption to travel.
Bands of rain and heavy showers will move east across southern parts of England and Wales during Monday afternoon and evening. 10-15 mm of rain is likely fairly widely with 20-30 mm in some places exposed to the strong south to southeasterly winds. 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.
