UK braces for thunderstorms and heavy rain with new warnings issued

The UK is set to experience more unsettled weather as the Met Office issues fresh thunderstorm warnings for Thursday. These warnings cover significant portions of England and Wales, with the potential for heavy rain and localized flash flooding.

The first warning is active from early Thursday morning across southeast England, while a second, broader warning for England and Wales begins at 06:00 BST and lasts until 22:00. This prolonged period of unsettled weather could bring downpours of up to 75mm (3 inches) in the wettest areas. Accompanying the rain will be lightning, hail, and gusty winds, potentially leading to hazardous driving conditions, road closures, and power outages.

While the rainfall may offer some relief to drought-stricken areas, experts caution that it is insufficient to replenish water supplies, with months of consistent wet weather needed. The forecast for the upcoming weekend, which includes several major festivals and events like the Reading and Leeds Festivals, Manchester Pride, and Notting Hill Carnival, also indicates continued rain and windy conditions, particularly in the south.

The persistent wet weather poses a risk of flash flooding, especially where the ground is dry and hard. The Met Office advises caution due to the potential for travel disruption and communities being cut off. Hailstones of 1-2cm are also possible.
