"Several areas of heavy, thundery showers will develop over England and Wales from Friday night before moving northwards during Saturday. Not everywhere within the warning area will see thunderstorms, and indeed some spells of warm sunshine are expected at times, but where thunderstorms do form, some torrential downpours are likely with frequent lightning, large hail and locally strong gusts. Significant flooding is possible where these do occur from surface water as well as from small, fast-responding watercourses."
Torrential downpours are affecting parts of the Anglia region as hot air arrives from the continent.
The white areas on the rainfall radar indicated rain rates in excess of 32mm per hour.
