“Properties could flood and there could be travel disruption.”

Among the rivers are risk are Upper River Mole, Ifield Brook, Gatwick Stream and Burstow Stream. This covers the Horley, Redhill and Crawley areas.

The Environment Agency said: “High river levels this morning may lead to flooding. Areas most at risk include low lying land and roads along the Upper River Mole.

"Further flooding is possible throughout today as river levels are remaining high due to heavy rainfall overnight.

“We are monitoring rainfall and river levels and clearing debris from weed screens.”

"Homes and businesses could be flooded, causing damage to some buildings.

A separate amber warning was issued for parts of the south Midlands, southern and southwest England which were ‘most likely to see the greatest’ amount of rain.

"However, anywhere within the warning area could have impactful rainfall through the course of Monday,” the spokesperson added.

“There is potential that 30-50 mm could develop in any part of the warning area, much of which could fall in six hours or less. Some locations could see 80-100 mm over the course of 12 to 24 hours.”
