Heavy rain and thunder is forecast tomorrow morning, prompting the Met Office to issue a second warning in as many days.
A yellow warning for rain will be in force across much of the country, including the whole of Gloucestershire, South Gloucestershire and Wiltshire, from 4am-11pm on Tuesday.
According to the Met Office widespread rain is expected with some very heavy rain possible, bringing some disruption from flooding.
Transport disruption is likely and fast flowing or deep floodwater is possible, causing a danger to life.
Rainfall could reach up to 32mm/hour in places and thunder is also forecast.
Tomorrow’s forecast for the South West states: “The often heavy showers will continue, with the risk of hail and thunder. They will ease by midday, but they will be replaced by outbreaks of rain, with strong winds.”
