Neil Davies, Environment Agency Flood Risk Manager, warned people to be on their guard because of the adverse weather.
He said: "These heavy showers may lead to localised surface water flooding in some parts of England. The rainfall is accompanied by strong westerly winds, with speeds of up to 70mph in the North East later today.
"The combination of these gusty conditions with high spring tides bring a risk of spray and wave overtopping leading to a risk of localised coastal flooding along parts of the south-west, north-west and north-east coasts of England."
The north of England and Scotland will be hit by more wind and rain over the coming days, while in the south showers will be interspersed with sunny spells.
