Thunderstorms are expected to hit Worcestershire within hours, leading to possible flooding, power cuts, property damage and travel chaos.
The Met Office has issued a yellow weather warning for thunderstorms, in place from midday to 10pm this evening.
The warning covers the whole of Worcestershire as well as much of Wales, the South West and the West Midlands.
The Met Office has warned motorists that driving conditions will be affected by sea spray, standing water and/or hail.
This will result in longer journey times if you are traveling by car or bus.
There may also be delays in train services as well as short term losses of power and other services.
They also warn that the flooding could affect “a few homes and businesses”, leading to damage to buildings and structures.
Damage can also be caused by lightning.
The Met Office website says: “Heavy showers will develop throughout the morning with isolated thunderstorms in the afternoon and evening.
“These will bring the potential for lightning, hail and heavy rain, with some places receiving 10-20mm of rain in an hour and a small chance of 40mm in 2-3 hours.
“Showers are expected to weaken over parts of Wales and South West England on Thursday evening, but will persist for longer in parts of central England and the Midlands.”
