Thunder storms are on their way after a period of intense sunshine, the Met Office has forecast.
The agency says north London could peak at 30 degrees this afternoon (Tuesday, July 20) at around 4pm. Shortly after that, the rain will begin.
The most intense rain shower is set to be around 5pm when thunder and lightning has been forecast. This is set to ease within the hour, with light rain predicted for the rest of the night.
A spokesperson said: “A dry and sunny start across the region.
“However, there is a risk of heavy thundery showers developing for the afternoon, with hail and gusty winds possible. Mostly very warm or hot, but cooler towards the east coast.”
