Residents are being warned that flooding to properties and low-lying areas near a river remains “possible” after heavy rainfall.

The Environment Agency has issued another red flood warning today (February 1) for the River Colne – and residents have been “strongly urged to take action now”.

It comes after heavy rainfall across the River Colne catchment over the last few days, which has caused river levels to rise.

The red flood warning covers parts of the river closest to the Moneyhill area of Rickmansworth, Maple Cross and Batchworth.

An amber flood alert has also been issued for the River Colne for the rest of Rickmansworth and in Watford.

The Environment Agency said on its website regarding the flood alert: “The main areas of concern are the Watford and Rickmansworth areas where river levels have risen the most. A flood warning has been issued to areas in Batchworth, Money Hill and Maple Cross along the River Colne.”

A statement on the flood warning added that while river levels have now peaked at the River Colne and will start to fall, potential rainfall in the early hours of February 2 could cause them to rise again.

The Envrionment Agency said: "Heavy rain has fallen across the River Colne catchment over the last few days and has caused river levels to rise. They have now peaked and will slowly start to fall today on Monday 1 February.

"No rainfall is forecast today but some rainfall is forecast from the early hours of Tuesday 2 February, and levels may rise again following this. 

“Flooding to properties and low lying areas around the River Colne, particularly within the Batchworth, Money Hill and Maple Cross areas remains possible today on Monday 1 February.

“Flood waters may be deep and fast flowing in these areas. Residents are strongly urged to take action now. Remain safe and be aware of your local surroundings.”
