Residents living near waterways across the county are being urged to "act now" as rivers and streams flood.

Nearly half a month's rain (30mm) hit much of Sussex yesterday, causing already high waterways to rise further.

Experts have issued two flood warnings, the highest alert, for the River Cuckmere, meaning residents and business owners should "act now" to prevent the worst effects of flooding.

The warnings are in place for Alfriston, Hellingly and Horsebridge, which are both near Hailsham. 

The Environment Agency (EA) spokesman said: "Flooding will also be extensive through fields, rural roads, gardens, and access along Litlington Road may be restricted by flood water.

"Only scattered showers are forecast Wednesday, with very little rain over the rest of the week."

However, the EA also said the river is unlikely to begin to fall until 10pm tonight, at the earliest.

The river might not return nearer to a normal level until Friday, the EA said.

"River levels are expected to peak higher than they have in recent weeks," the spokesman added. 

"Flood water can be deep and dangerous, please take care if walking near the river in Alfriston. Please plan to avoid driving on routes vulnerable to flooding." 

Elsewhere in Sussex, eight flood alerts have been issued. This means flooding is possible and residents are urged to be prepared.

The flood alerts are in place for:

  • The River Cuckmere at Westdean and Arlington
  • Combe Haven, between Bexhill and Hastings
  • The River Rother at Roberstbridge
  • The Upper Ouse from Barcombe Mills to Balcombe
  • The River Uck at Uckfield
  • River Adur east branch at Burgess Hill
  • Upper River Medway at Hartfield
  • Upper River Mole at Crawley and Gatwick
  • Western Rother at Midhurst

The EA's experts are continuing to monitor river levels and weather forecasts but suggest most of the rivers will not return to normal levels until later in the week.

If a flood alert is issued, the EA says you should:

  • be ready to follow your flood plan
  • have insurance documents and any medications ready
  • avoid walking, cycling or driving through any flood water
  • move any livestock and farming equipment away from areas likely to flood
