A potent thunderstorm warning has been issued for Glasgow, with forecasters predicting a high risk of frequent lightning strikes, torrential downpours, and strong gusts throughout the afternoon. The warning, which takes effect from 13:00 BST today, Tuesday, June 11, will last until 20:00 BST.
The Met Office warns that severe weather could lead to significant disruption, with a risk of localised flooding in areas prone to poor drainage. This may impact homes and businesses, while travel conditions are expected to deteriorate due to surface water and reduced visibility. Additionally, public transport services may be delayed or cancelled, and there is a small chance of power cuts and other service disruptions.
While Glasgow is at the epicentre of this warning, the affected area spans central and southern Scotland, encompassing regions from Ayrshire to the Lothians. Residents in these areas are advised to secure loose outdoor items, avoid unnecessary travel during the storm's peak, and be prepared for sudden changes in weather conditions. Temperatures in Glasgow will remain around 17-19°C, but wind gusts associated with the thunderstorms could reach 20-30 mph.
The Met Office attributes this weather pattern to summer convection, where warm, moist air rapidly rises to form towering cumulonimbus clouds, leading to intense but often localised storms. Residents are urged to stay updated with the latest forecasts and warnings and take necessary precautions for their safety. This includes unplugging non-essential electrical appliances during a lightning storm and avoiding sheltering under trees.
While the most intense period is expected in the afternoon, unsettled weather may continue into the evening. Authorities will closely monitor the situation and respond to any incidents arising from the severe weather. Residents are cautioned to be aware of potential floodwaters, which can appear deeper and move faster than they seem.
