Two severe flood warnings remain in place in Gloucestershire with the Environment Agency advising people to "be vigilant" as more rain is forecast.

The warnings, indicating a danger to life, are in place on the River Severn from Gloucester to the Rodley area.

Nick Green from the agency said the warnings "relate to the times directly after each high tide".

He said: "We saw some overtopping of the flood banks on Sunday and we think we may see the same happening today."

Severn Bore Facts

  • Severn Estuary, which empties into the Bristol Channel, has the third largest tidal range in the world - about 49 feet (15m)
  • During the highest tides rising water is funnelled up the estuary into a wave that travels upstream against the river current at a speed of 8 to 13mph (12.8 to 21km/h) depending on conditions
  • A tide measuring 9m (29.5ft) or above at Sharpness will, with the right conditions, provide a visible bore wave
  • Tides measuring 9 to 9.2m (29ft 6ins to 30ft ) are given a one-star rating, while tides over 10.3m (33ft 9ins) are five-star
  • This year there are bores predicted every month except May

Over the weekend, the combination of a five-star bore and tidal surge left some homes in Minsterworth flooded and closed the nearby A48.

With eight flood warnings still in place across the county and another four-star bore expected later, the agency is advising people to "be prepared".

"As we've seen in the last couple of days it raises levels extremely quickly behind the bores and we saw some overtopping of the flood banks on Sunday," said Mr Green.

"And we think may see the same happening today, even though it's a lower star bore.

"We've got more rain forecast for the next few days and waters are high, so our advice is to be prepared, be vigilant and check for the latest updates."
