The yellow thunderstorm warning is in effect from midnight to 10 a.m. on Saturday as a plume of warm air from the continent pushes north across the southern half of the UK, increasing the risk of thunderstorms in southern counties.
Many places within the warning area are unlikely to see a thunderstorm at all,” said Met Office Chief Meteorologist Andy Page, “but those places that do see one may well see impacts from heavy rain and frequent lightning strikes.
“A few locations may see up to 20 – 30 mm of rain in an hour, with a small chance of 50 mm in 2 to 3 hours, most likely near the south coast.” The threat of thunderstorms diminishes as Saturday morning progresses. However, as this band of warm air continues to push north across the UK, more thunderstorms and heavy downpours are possible on Sunday. We will keep an eye on this risk and may need to issue another alert if the potential consequences become clearer. Please check the forecast for your area on a regular basis for any updates.”
