The environmental agency has issues a Flood Alert for both The Rivers Beam and Rom

This will be caused by the predicted heavy rain and thunderstorms which are forecast to affect the London area over the next 48 hour period. While uncertainty remains around exact timings and which areas will experience the heaviest rain there is a possibility that rivers could respond quickly and overtop their banks.

Flooding to low lying land, roads and riverside gardens is possible. Surface water flooding may also affect low lying areas. We recommend you monitor local weather conditions and avoid walking, cycling or driving through flood water.

We are monitoring the situation closely and have staff out on the ground checking and clearing trash screens.

We will update this message in the next 12 hours or as 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.
