Thunderstorms in southern England brought torrential rain, large hail and flash flooding on 18 July, 2017.
Emergency services responded to flash flooding in Kent, Berkshire and Cornwall, where helicopters were used to carry out flood rescues.
Cornwall
Major flash flooding hit the coastal village of Coverack in Cornwall, on 18 July, 2017.
Torrents of water over 1 metre deep swept through the village after a period of heavy rain. Flood water and debris made roads in and out of the village impassable.
Two people trapped in their home had to be rescued by a coastguard helicopter.
Local authorities said that around 50 properties were affected and families were forced to evacuate. An emergency centre was opened in Truro’s County Hall by Cornwall County Council to respond to the flood situation.
Cornwall County Council said: “Cornwall’s emergency centre leading response to flash floods in Coverack. Members of Cornwall Council’s Localism team are supporting local residents affected by flooding in Coverack.”
According to the latest reports, all those trapped on their homes had been rescued and no casualties were reported.
Rainfall
The heavy rain was extremely localised, with none of the main weather stations in the area recording significant rainfall levels.
John Curtin, Executive Director of Flood & Coastal Risk Management, Environment Agency, said via Social Media that weather radar images show just how localised the Coverack storm was and that unverified totals look like 100mm of rain in three hours.

Further Rainfall Warnings
The Met Office issued further warnings for heavy rain on 19 July.
“Thunderstorms, with locally torrential downpours will continue to move north across England and Wales in the early hours of this morning. Although the thunderstorms will tend to ease from the south later in the night, further, possibly severe storms may break out again this afternoon, probably focused over parts of northeast Wales, central and northern England. Although some places will miss the thunderstorms, there is a chance of localised sudden flooding of homes, businesses and roads. Frequent lightning and large hail may be additional hazards, the latter bringing potential for disruption to power networks. This warning has been updated to keep the risk going over southern England through the early hours of this morning.”
