A flood alert has been issued. Groundwater levels in East Surrey and South London rose during the winter following higher than average rainfall. Levels continued rising until late March and remained high in April. The Caterham Bourne is in flow since mid-March and is still flowing in the Whyteleafe and Kenley area, and the Environment Agency is monitoring the levels and flow of the Bourne in Kenley Bourne Park. However, groundwater levels across the area have now started to fall, although some properties with deep basements in and around Purley and low-lying land near the Caterham Bourne could still experience flooding. Whilst property and garden flood risks have reduced, riparian owners are reminded to keep clear any sections of river that flow through their land. The Environment Agency is monitoring the situation alongside Surrey County Council, Tandridge District Council and the London Borough of Croydon. We will update this message on Thursday 23 May 2024, or sooner if the situation changes.

What you should consider doing now
- Monitor local water levels and weather conditions.
- Get ready to act on your flood plan if you have one.
- Move your car or other vehicles to higher ground, if it is safe to do so.
- Prepare a flood kit of essential items including a torch with spare batteries, mobile phone and charger, warm clothes, home insurance documents, water, food, first aid kit and any prescription medicines or baby care items you may need.
- Check that you know how to turn off your gas, electricity and water mains supplies.
- In rural locations, farmers should consider moving livestock and equipment away from areas likely to flood.
- Avoid walking, cycling or driving through flood water - 30 cm of fast-flowing water can move a car and 6 inches can knock an adult off their feet.
- Flood water is dangerous and may be polluted. Wash your hands thoroughly if you’ve been in contact with it.
Businesses

Whilst some places may remain mostly dry, areas of heavy rain and some thunderstorms are expected to develop from around mid-morning.
In the south of this warning area, the focus is likely to be slow-moving heavy showers and thunderstorms, perhaps with hail and lightning, which should gradually ease away later on Tuesday evening.
Meanwhile, further north in the warning area, early showers are likely to merge into more general rain, this heavy and thundery at times, and will persist onwards into Wednesday (which is covered by a separate warning).
Across the warning area, 20-30mm in 1 hour or less is possible (but perhaps most likely to the south of London), with a few places perhaps receiving 40-50mm in 2-3 hours.
What should I do?
Consider if your location is at risk of flash flooding. If so, consider preparing a flood plan and an emergency flood kit.
Prepare to protect your property and people from injury. Before gusty winds arrive, check to ensure moveable objects or temporary structures are well secured. Items include; bins, garden furniture, trampolines, tents, gazebos, sheds, and fences.
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.
If you find yourself outside and hear thunder, protect yourself by finding a safe enclosed shelter (such as a car). Do not shelter under or near trees, or other structures which may be struck by lightning. If you are on an elevated area move to lower ground.
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. For further details see https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings
