The UK has been issued a yellow weather warning for thunderstorms today, which began at 9am BST and covers large parts of the country. Forecasters warn that heavy downpours, lightning strikes, hail, and gusty winds pose a significant risk of disruption to daily activities and infrastructure.
Central and southern England, much of Wales, and parts of Northern Ireland are expected to see rapid development of thunderstorms throughout the day. Localised heavy rainfall could bring up to 30mm in an hour and potentially 50-60mm over just a few hours in some areas - a risk that has been heightened due to surface water flooding concerns, especially in urban zones where drainage systems may be overwhelmed.
The perfect storm for these thunderstorms is created by a mix of warm air and atmospheric instability, with temperatures ranging from 18C to 22C. While winds are generally light at around 5-10mph, they could reach significantly higher gusts during intense activity, up to 30-40mph.
The public should prepare for potential disruptions, including delays on roads and railways due to poor visibility and standing water, as well as a small risk of power cuts. Residents are advised by the Met Office to secure loose outdoor items and avoid unnecessary travel when severe weather hits.
Regions like the Midlands, South East, and South West England are most susceptible to these conditions, alongside much of Wales from Cardiff to Anglesey. In Northern Ireland, Antrim and Down counties fall within the warning area, while Scotland is largely unaffected but may still see isolated showers. The current warning remains in place until later tonight before easing overnight.
