Coastal communities in east Suffolk are at risk of flooding tonight as heavy rainfall and melting snow cause river levels to rise, officials have warned.

The Environment Agency says flooding is “likely” at the Chediston watercourse in Halesworth; and is “possible” at the Rivers Blyth, Deben and Lark, and Bramfield and Wrentham watercourses.

A statement on the organisation’s website reads: “This message has been issued because of the rainfall over the last three hours combined with the melting snow from the previous week. This means that river levels are expected to continue to rise over the next few hours.

“The forecast is for continued light rainfall for the next four to six hours. We are expecting river levels to remain high and responsive to further rainfall on the saturated catchment.”

Immediate action is required to tackle the flood dangers in Halesworth, the Environment Agency has cautioned.

Areas most at risk are the Thoroughfare, Chediston Street, Saxons Way and School Lane, and the A144 and the railway line.

The Environment Agency statement adds: “We will continue to closely monitor levels and update this message as necessary.”
