The first Met Office warning covers the South West and extends from the West Midlands to the South East and is in force on Friday from 12 p.m. to 8 p.m. It also encompasses a sizable portion of Wales, which includes Swansea and Cardiff.
According to the weather service, buildings will most likely sustain damage from lightning strikes during storms.
Additionally, it warned that driving may be impacted by hail, spray, and/or standing water due to the probability of up to 40mm (1.5 in) of rain in three hours. It also mentioned the likelihood of power outages and the potential for rail delays.
Early on Friday, there might be a few thunderstorms in southern and southeast England, but by the middle of the day, the Met Office predicted that the showers will spread out more inside the warning area.
Where thundery showers do arrive, they will bring frequent lightning, strong winds, possibly some large hail, and brief periods of heavy rain. Some areas will remain dry.
“A very small chance of 30-40mm falling in three hours” was mentioned for South West England.
