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.”
