Surrey BBC Weather predicts 10hrs of thunder or rain: Exact times storm could hit

An updated Met Office rainfall map has revealed where in Surrey the heaviest rainfall is expected on Sunday (June 18). It comes as BBC forecasters have predicted up to seven hours of thunder in areas including Horley, Staines, and Woking.

Towns such as Guildford, Farnham, and Dorking have also been forecast hours of thunder, while rain is set to dominate throughout the afternoon and into the evening. A Met Office rainfall radar map has shown a band of heavy rain moving across the county.

This is expected to bring with it up to four and even eight millimetres of rain per hour in some areas, with two millimetres per hour forecast for the majority of Surrey. A yellow weather warning for thunder remains in place.

Met Office meteorologist, Rachel Ayers, said: “As we look ahead to Sunday, we have got a couple of yellow thunderstorm warnings in force. These cover most parts of England, Wales, and Northern Ireland.

“These are because we are going to see some pretty heavy showers that could bring some localised flooding and disruption. Within these showers, we will see some pretty frequent lightning, hail, and strong winds.

“But there is a bit of uncertainty into the exact detail of where we’ll see these showers.” She added: “Those showers will really get going into Sunday evening and overnight, merging together to form longer spells of thundery rain that will push northwards.” Highs of 24C or 25C are expected in parts.
