Flash flooding led to the closure of Saltney High Street this afternoon (Saturday June 11).
Heavy rain caused a pool of water to gather under the railway bridge close to the England-Wales border.
North Wales Police has tweeted that all traffic is being diverted down Boundary Lane at the moment and warns drivers to expect delays.
Travel website Inrix says: "The A5104 High Street in both directions closed, slow traffic due to flooding between Victoria Road / Bridge Street and River Lane / Boundary Lane."
'Cars stuck in water'
The site also states that River Lane is closed in both directions as a knock-on effect from the flooding in High Street with claims four cars are stuck in the water.
Hannah Jones wrote on Twitter: "Avoid Saltney High Street. Flooding under the railway bridge by Asda several feet deep - Chester council have been informed."
Meanwhile, resident John Murray, of Queen's Park, reports that The Falcon pub in Lower Bridge Street, Chester, had to close after cellar was flooded.
Chester Fire Station confirmed no flooding-related call-outs and said the down-pour failed to dampen the spirits of those attending their open day.
The deluge will also have soaked thousands of race-goers attending Chester races this afternoon.
Today's flooding comes after large parts of Ellesmere Port including the town centre and Great and Little Sutton were yesterday (Friday, June 10)affected by a flash-flood which led to the early closure of Sutton Green Primary School in Armthorpe Drive when storm waters backed up through the toilets.
