The Met Office has issued a yellow weather warning for thunderstorms, set to affect parts of Cornwall today. The warning, which covers areas including Falmouth and surrounding regions, is active from 12:00 BST until 20:00 BST. Residents are urged to be vigilant as the conditions could lead to significant disruption across the affected areas.
Forecasters predict that while not all areas within the warning zone will experience thunderstorms, those that do could see intense downpours. Rainfall amounts could reach between 20-30mm in an hour, with some localised spots potentially receiving up to 50mm over a few hours. This volume of rain carries a risk of flash flooding, particularly in urban areas and on low-lying roads, which could make driving conditions hazardous.
In addition to heavy rain, lightning strikes are a distinct possibility, posing a risk to power supplies and potentially leading to localised power cuts. Hail and strong gusty winds, potentially reaching speeds of 30-40 mph, could also accompany the storms. Such conditions can cause damage to trees and structures, as well as making driving particularly challenging for motorists.
For England, the warning is concentrated solely on parts of Cornwall, with other regions currently unaffected by similar alerts. Scotland, Wales, and Northern Ireland are not currently under any Met Office thunderstorm warnings, although localised showers remain a possibility in various areas across the UK. The Met Office advises checking local forecasts for the most up-to-date information.
Practical safety advice for those in the affected areas includes securing any loose items in gardens or on balconies that could be blown away by strong winds. It is also recommended to avoid seeking shelter under trees during a thunderstorm due to the risk of lightning strikes. Motorists should be prepared for sudden changes in road conditions, including reduced visibility and surface water, and consider delaying non-essential travel if conditions deteriorate significantly.
This warning follows a period of mixed weather across the UK, with some regions experiencing warmer temperatures while others have seen more unsettled conditions. The current forecast suggests that while this particular warning is localised, the broader weather pattern remains dynamic, with further convective activity possible in other parts of the UK in the coming days, though not currently under specific warnings.
