Teddington RNLI is warning locals to be aware of fast-rising Thames tides after two walkers, one of them pregnant, had to be rescued in Richmond last week.

The two friends were walking along Richmond's towpath on Sunday 7 April when their path to the town centre was cut off by high tide.

One walker described the incident in a Facebook post, saying: "Our main concern at first was getting our trainers a bit wet – little did we know that by the time we made our way to the next available exit, around five minutes' walk from our bench, our feet would get more than wet. 

"The extremely cold water had risen to my knees and the top of my friend's thighs. We called the police, who told us that a lifeboat would get to us in 15 minutes.

"When they arrived, the crew really looked after both my friend and me – I couldn't be more grateful to the volunteers that day. 

"Without them we could have been done for."

Teddington RNLI have said the tidal portion of the river, downstream from Teddington Lock, can often be accompanied with "strong, fast currents".

Tim James, the RNLI helm in charge of the rescue, said: "Walking along the River Thames towpaths during a high or flooding tide can present several hazards, especially if there has been heavy rainfall. 

"The river flow will be faster and more powerful, causing sections of the towpaths to become submerged making it very difficult to see the path, creating an obvious danger near the riverbanks, which shelve off steeply.

"Remember even knee-deep water can sweep you off your feet.

"If possible, it's best to anticipate this and avoid walking through flooding or high water. Be aware of your surroundings and when the tide is likely to rise. 

Walkers are encouraged to look out for flood warnings and advice here, as well as tide times here. also check the tides here.

"If you do get trapped by flood water, stay calm and look for higher ground, do not attempt to wade through the flood water. Call 999 and ask for the London Coastguard and await rescue," added Mr James.
